Öğe Accuracy of Different Lens Power Calculation Formulas in Patients With Mature Cataracts(Springernature, 2023) Yesilkaya, Elif Ceren; Garip, RuveydeIntroduction To compare the prediction accuracy of lens power calculation formulas in patients undergoing mature cataract surgery. Methods A total of 90 operations involving the Alcon SA60AT IOL implant (Alcon, Geneva, Switzerland) were analyzed in terms of mean refractive prediction error (PE) and mean absolute prediction error (MAE) using backward calculation in a retrospective design. Results A negative PE was observed in SRK/T, Holladay 1, Holladay 2, Hoffer Q, Haigis, and Emmetropia Verifying Optical (EVO) formulas. In contrast, positive PEs were observed in Barrett Universal II (BAUII), Kane, and Radial Basis Function (RBF) formulas. Negative PE was observed with all formulas, except BAUII, in patients with a shallow anterior chamber depth (ACD). While the SRK/T, Holladay 1, BAU, Kane, and RBF formulas demonstrated positive PE, the Holladay 2, Hoffer Q, Haigis, and EVO formulas indicated negative PE. In patients with deep ACD, positive PE was observed in all formulas, barring Holladay 2 and EVO. No significant differences were identified between the formulas concerning MAE and percentages of 0.25 diopter (D), 0.50 D, 0.75 D, and 1.0 D across all study groups. Conclusion Although the new generation formulas provide very good results, achieving the best with a single formula is still impossible.Öğe Büyüme Hormonu Tedavisi Alan Çocuklarda Ön Segment Parametreleri ve Aksiyel Uzunluğun Değerlendirilmesi(2022) Garip, Ruveyde; Ozal, Sadık; Dilek, Emine; Tütüncüler, FilizAmaç: Konjenital izole büyüme hormonu eksikliği nedeniyle büyüme hormonu tedavisi alan hastaların topografik kornea ve ön segment parametrelerini değerlendirmek, bu bulguları sağlıklı gönüllüler ile karşılaştırmak ve büyüme hormonu tedavisinin gözün ön segment parametreleri üzerinde herhangi bir etkisi olup olmadığını değerlendirmek. Gereç ve Yöntem: Bu karşılaştırmalı çalışmaya konjenital izole büyüme hormonu eksikliği olan 30 hastanın 30 gözü ve 30 sağlıklı katılımcı dahil edildi. Tüm katılımcılara tam oftalmolojik muayene yapıldı. Korneal topografik ölçümler ve ön segment biyometrisi Scheimpflug topografi cihazı kullanılarak değerlendirildi. Aksiyel uzunluk, temassız kısmi koherans interferometre ile ölçüldü. Bulgular: İki grup arasında yaş ve cinsiyet açısından anlamlı fark yoktu (p=0,174 ve p=0,174). Büyüme hormonu tedavisi alan çocuklarda ortalama merkezi kornea kalınlığı ve kornea hacmi sağlıklı bireylere göre istatistiksel olarak anlamlı derecede yüksek bulundu (p=0,042 ve p=0,01). Ancak iki grup arasında keratometri değerleri, ön kamara derinliği, ön kamara hacmi, iridokorneal açı genişliği, aksiyel uzunluk ve kırma kusurları açısından istatistiksel olarak anlamlı fark bulunmadı (p>0,05). Sonuç: Merkezi kornea kalınlığı ve kornea hacmi değerleri büyüme hormonu tedavisi alan hastalarda daha yüksekti. Bulgularımız, gözün büyüme hormonu için hedef organlardan biri gibi göründüğünü göstermektedir. Farklı oküler dokularda büyüme hormonunun tam mekanizmasını tanımlamak için tanımlayıcı çalışmalara ihtiyaç vardır.Öğe Changes in intra-ocular pressure, ocular pulse amplitude and choroidal thickness after trabeculectomy(Taylor & Francis Ltd, 2023) Cicek, Ugur; Garip, Ruveyde; Solmaz, Banu; Altan, CigdemBackground The aim of this study was to investigate the IOP, ocular pulse amplitude (OPA) and choroidal thickness (CT) changes after trabeculectomy and to determine whether trabeculectomy has an effect on ocular blood flow. Methods This retrospective, comparative case series was conducted with 33 eyes of 33 patients who underwent trabeculectomy due to uncontrolled glaucoma. The fellow eyes of 20 patients who were followed up with medical therapy were included as a control group. IOP and OPA were evaluated using a dynamic contour tonometer. Subfoveal choroidal thickness (SFCT) was obtained with enhanced depth imaging (EDI) mode of Spectralis-OCT. Results The mean IOP was 21.6 +/- 6.3 mmHg at baseline and 13.8 +/- 0.9 mmHg after trabeculectomy (p < 0.001), and the mean OPA was 4.1 +/- 1.5 at baseline and 2.6 +/- 1.6 mmHg after trabeculectomy (p < 0.001). The mean SFCT was 292.2 +/- 63.2 mu m at baseline and 303.8 +/- 70.4 mu m after trabeculectomy (p = 0.024). The change in OPA was strongly positively correlated with the change in IOP (r = 0.597, p < 0.001) and SFCT change was positively correlated with OPA change (r = 0.34, p = 0.05). There was no difference between the two groups in terms of IOP, OPA and SFCT values measured after trabeculectomy (respectively, p = 0.264, p = 0.627 and p = 0.949). Conclusion The large IOP decrease following trabeculectomy causes a decrease in OPA and choroidal thickening. On the other hand, trabeculectomy has no effect on OPA change.Öğe Comparison of macular thickness change by optical coherence tomography after uncomplicated cataract surgery in eyes with and without exfoliation syndrome(Springer, 2021) Kemer Atik, Burcu; Kirmaci Kabakci, Asli; Garip, RuveydePurpose To evaluate the effect of exfoliation syndrome (ES) on macular thickness after uncomplicated cataract surgery. Methods 87 patients (87 eyes) who underwent uncomplicated cataract surgery were included in the study. Optical coherence tomography (OCT) films were taken in addition to the routine ophthalmologic examination before the surgery and at postoperative 1st week, 1st, 3rd and 6th months. Mean macular thickness, central macular thickness and macular volume values obtained from the 6 x 6 mm macular map in the OCT measurements were recorded. The cases were divided into two groups as Group 1: cases without ES and Group 2: cases with ES. The macular values obtained from the OCT measurements of the two groups were compared with statistical methods. Results Eighty-seven eyes were included in the study; while 51 had no ES (Group 1), 36 had ES (Group 2). The mean age of all cases was 66.70 +/- 9.13 years. While the mean macular thickness, central macular thickness and macular volume were similar at the preoperative visit and the postoperative 1st week of all cases (eachpvalue > 0.05); these values were higher at the postoperative 1st, 3rd and 6th month compared to the preoperative and the postoperative 1st week values (eachpvalue < 0.05). The highest values were obtained at the postoperative 1st month; while the values of 1st, 3rd and 6th months were statistically similar (eachpvalue > 0.05). No statistically significant difference was observed between Group 1 and Group 2 in terms of macular volume, central macular thickness and average macular thickness in these periods. Conclusion Exfoliation syndrome has not been evaluated as a risk factor for an increase in macular thickness after uncomplicated cataract surgery.Öğe Corneal dellen development after strabismus surgery(Taylor & Francis Inc, 2021) Sakallioglu, Ahmet Kursad; Garip, RuveydeThis study aimed to evaluate the frequency of corneal dellen development, the healing process, and associated factors that affecting the development and healing of corneal dellen formation after strabismus surgery. In this retrospective study, the records of 714 eyes of 1264 patients who underwent limbal approach strabismus surgery between January 2005 and January 2020 were examined and 47 eyes of 44 patients with corneal dellen were included in the study. Demographic features, ophthalmological examination findings, dellen occurrence and healing time, dellen localization, and the type of surgery were obtained from the medical records of the patients. Corneal dellen development rate was found to be 3.7%. A moderate positive correlation was determined between both mean dellen occurrence time (r = 0.387, p = .007), and mean dellen healing time (r = 0.376, p = .014) with age. In patients who underwent monocular two muscle surgery had significantly higher rates of dellen formation compared to patients who underwent single muscle surgery (p<0.001). Corneal dellen was significantly higher in eyes undergoing single muscle rectus resection surgery than single muscle rectus recession surgery (p < .001). It was observed that corneal dellen developed more frequently after resection surgery, developed earlier in younger patients, and heals later in elderly patients. Therefore, patients can be followed up closely, keeping in mind the development of dellen, especially after resection surgery.Öğe Diyabetik Retinopatili Hastalarda Sağlıkla İlişkili Yaşam Kalitesini Etkileyen Faktörlerin Değerlendirilmesi(2022) Sakallioglu, Kursad; Akaray, İrfan; Kaya, Sultan; Kaya, Özlem; Köse, Gizem; Garip, Ruveyde; Güçlü, HandeAmaç: Diyabetik retinopati (DRP) hastalarında sağlıkla ilişkili yaşam kalitesini (SİYK) etkileyen faktörlerin araştırılması. Gereç ve Yöntemler: Çalışmaya tip 2 diyabet nedeniyle DRP açısından takipli 400 hastanın 800 gözü katılmıştır. Hastalar oftalmolojik muayene sonrasında Kısa Form-36 (SF-36) anketini doldurmuştur. SF-36’ya göre fiziksel işlev, fiziksel rol, bedensel ağrı, genel sağlık, canlılık, sosyal işlevsellik, duygusal rol ve ruh sağlığı, fiziksel ve zihinsel bileşen özet ölçümleri hesaplandı. Hastaların demografik özellikleri hasta dosyalarından not edilmiştir. İki bağımsız grubu karşılaştırmak için normal dağılım varsayıldığında bağımsız örneklemlerde T-testi, verilerin normalliği reddedildiğinde Mann-Whitney U testi kullanıldı. İkiden fazla olan bağımsız grupların karşılaştırılmasında Bonferroni veya Tamhane’s T2 düzeltmeli ANOVA testi, sayısal değişkenler arasındaki ilişki Pearson korelasyon testi ile değerlendirildi. Anlamlılık düzeyi p<0,05 olarak kabul edildi. Bulgular: Kadınların (p<0,001), diyabet süresi 15 yıldan fazla olanların (bedensel ağrı için p=0,002; diğerleri için p<0,001) SİYK düşük saptandı. Fiziksel ve zihinsel bileşen özet ölçüm değerleri 65 yaşından büyük hastalarda düşüktü (sırasıyla p=0,046, p=0,034). Panretinal fotokogülasyon (PRFK) yapılan ve iskemi saptanan hastalarda SİYK değerleri bedensel ağrı hariç (PRFK için p=0,178; iskemi için p=0,252) anlamlı düşük saptandı (p<0,05). Proliferatif diyabetik retinopati (PDR) hastalarından DRP(-) hastalara doğru SİYK bedensel ağrı hariç anlamlı şekilde yükseldi (p<0,05). Görme keskinliği 20/40’tan az olan hastalarda ruh sağlığı (p=0,335) ve bedensel ağrı (p=0,069) hariç tüm alt grup değerleri düşüktü. Sonuç: Kadın cinsiyetin, 15 yıl ve üzerinde diyabet öyküsünün, kısmen ileri yaşın, daha fazla PRFK yapılmış olan hastaların, retinal iskemisi olan hastaların ve daha düşük görme düzeyine sahip hastaların SİYK’sının düşük olabileceği göz önünde bulundurulması, bu hastaların tedavi yönetiminde daha dikkatli olmamızı sağlayabilirÖğe Evaluation of Axial Length Changes after Combined Phacovitrectomy for Macula-off Rhegmatogenous Retinal Detachment(2019) Kupeli, Ayca; Ozal, Sadık; Ozal, Ece; Garip, RuveydeObjectives: To evaluate the reliability of optical biometry for correct intraocular lens (IOL) power calculation in eyeswith macula-off rhegmatogenous retinal detachment (RRD) via comparing the axial lengths (AL) measured with opticalbiometry preoperatively and postoperatively.Methods: This retrospective study was conducted with 25 eyes of 25 patients who underwent combined surgery (phacoemulsificationand pars plana vitrectomy (PPV)) with the diagnosis of RRD with macular involvement. Best-correctedvisual acuity (BCVA), biomicroscopic examination, intraocular pressure measurement and full fundoscopic examinationwere performed in all patients. Axial length was measured using optical biometry in all patients. The AL measurementswere repeated in the postoperative third month in the patients using gas tamponade during vitreoretinal surgery and inthe third month after the silicone oil removal in patients using silicone-oil tamponade during vitreoretinal surgery.Results: The mean age of the patients was 61.60±7.33. Fifteen patients (60%) were female, and 10 (40%) were male.Postoperative BCVA values (0.40±0.28) were significantly higher than the preoperative BCVA values (0.14±0.22) (p<0.05).The preoperative mean value of AL was measured as 24.66±1.90 and the postoperative mean value of AL was 24.67±1.91.There was no statistically significant difference between the measured AL values in the preoperative and postoperativeperiods (p=0.258).Conclusion: Combined surgery (phacoemulsification and PPV) is a frequently applied method in RRD treatment. Thecorrect AL measurement is important for the removal of refractive errors due to AL measurement in patients with macula-off RRD. Optical biometry provides accurate results in these casesÖğe Evaluation of Clinical Findings, Optical Coherence Tomography, Fundus Fluorescein Angiography, and Indocyanine Green Angiography Imaging in Patients with Polypoidal Choroidal Vasculopathy(2020) Garip, Ruveyde; Yasa, Dilek; Ozkaya, AbdullahObjectives: The aim of this study was to describe clinical findings as well as spectral-domain optical coherence tomography (SD-OCT), fundus fluorescein angiography (FA), and indocyanine green angiography (ICGA) findings of polypoidalchoroidal vasculopathy (PCV).Methods: This retrospective, observational case series included 144 eyes of 103 patients who were diagnosed with PCVbetween January 2014 and August 2016. Best corrected visual acuity, 90-diopter lens slit-lamp fundus biomicroscopyexamination findings, color fundus photography, SD-OCT, FA, and ICGA findings were evaluated at the time of diagnosis.Results: Sixty-six patients (93 eyes, 64.1%) were male and 37 (51 eyes, 35.9%) were female. Sixty-two (60.2%) patientshad unilateral involvement. The most common SD-OCT finding was retinal pigment epithelial detachment (PED). Red-orange subretinal lesions were seen in 20 eyes (13.9%). There was a single polyp in 21 (14.6%) eyes, and more than 1 polypin 123 (85.4%) eyes observed with ICGA imaging. The polyps were located in the peripapillary area in 10 (6.9%) eyes, themacular area in 91 (63.2%) eyes, and the extramacular area in 1 (0.7%) eye. A significant branching vascular network wasseen in the ICGA images of 112 (77.8%) eyes.Conclusion: In this study, the majority of patients were male, with unilateral macular polyps. A serous PED and an exudative pattern were the most common clinical manifestations. SD-OCT showed specific findings for PCV, but ICGA wasthe most useful test for diagnosis.Öğe Evaluation of Orbit Vector Relationships in Different Types of Skeletal Malocclusions(Galenos Publ House, 2022) Garip, Ruveyde; Meric, Pamir; Ozveren, Mehmet; Ozveren, NeslihanObjective: This study aimed to determine the orbit vector relationships between different types of malocclusion supported by cephalometric analysis. Materials and Methods: This retrospective study was conducted on 69 patients who were diagnosed with orthodontic malocclusion. Demographic information, such as age and gender, were provided from the medical records of the patients. Cephalometric analysis was performed by an expert orthodontist to determine the anteroposterior skeletal relationship. The orbit vector relationship was evaluated by digital patient photographs taken by the Frankfort horizontal plane by two different ophthalmologists. Results: The mean age of the patients was 14.58 +/- 3.95 (range, 8-28) years. Forty-five (65.2%) of the patients were female and 24 (34.8%) were male. Positive orbit vector patients had significantly higher SNA measures and ANB readings than negative orbit vector patients (pSNA=0.014, pANB=0.001). There was no difference in orbit vector status between Class I and II malocclusion groups (p=0.580). Negative vectors were more common in the Class III group than in the Class I (p=0.039) and Class II (p=0.004) groups. Conclusion: The majority of patients in the Class I and II groups had a positive orbit vector, whereas patients in the Class III group had a negative orbit vector relationship.Öğe Evaluation of the educational quality and reliability of YouTube videos addressing eyelid ptosis surgery(Taylor & Francis Inc, 2022) Garip, Ruveyde; Sakallioglu, Ahmet KursadPurpose: To evaluate the educational content, quality, and reliability of YouTube videos addressing anterior approach ptosis surgery. Methods: A search on YouTube using the term ptosis surgery was performed between March 20 and March 26 2021. The quality, reliability, and accuracy of the contents of 38 videos meeting the inclusion criteria were evaluated by two independent ophthalmologists using the DISCERN questionnaire and the Journal of the American Medical Association (JAMA) benchmark criteria. The Global Quality Score (GQS) and a surgical scoring system were used to assess the educational value of the content. Results: The mean DISCERN score was 32.8 +/- 10, and the mean JAMA score was 1.3 +/- 0.5, indicating poor quality; the mean global quality score was 3.1 +/- 1.1, indicating moderate quality; and the mean surgical score was 7.5 +/- 2.7, indicating moderate to good quality. The surgical, DISCERN, and GQS scores of the videos uploaded by physicians were significantly higher than those of the videos uploaded by private clinics (p = .015, p = .049, and p = .01, respectively). There was a significant positive correlation between the surgical, DISCERN, JAMA, and GQS scores (p < .001). A significant positive correlation was found between video duration and surgical score (p = .013), DISCERN score (p < 0.001), and GQS score (p < 0.001). Conclusion: Videos with known sources, uploaded by physicians, and supported by audio narration may be useful in obtaining educational information. However, the available videos are not a reliable source of educational information about ptosis surgery.Öğe Evaluation of the Efficacy of Pneumatic Vitreolysis Treatment for Symptomatic Vitreomacular Traction Syndrome(2022) Kupeli, Ayca; Ozal, Ece; Garip, Ruveyde; Ozal, SadıkPurpose: To evaluate the posterior vitreous release rates after a single injection of expansile gas in patients with focal vitreomacular traction (VMT) syndrome. Materials and Methods: Thirteen eyes of 13 consecutive patients with focal symptomatic VMT were reviewed retrospectively. Intravitreal injection of 0.3 mL of pure perfluoropropane (C3F8) was performed. Patients were instructed to bob their head forwards and backwards similar to the head movements of a ‘drinking bird’ until VMT release. A full ophthalmic examination and optical coherence tomography (OCT) was performed at each visit. Results: The mean age of the patients was 66.23±10.01. Seven patients (53.8%) were female, and 6 patients (46.2%) were male. VMT was released in 12 patients (93.7%), and the mean release time was 7.58 days (1-14 days). In two eyes (15.4%) with VMT associated with the full thickness macular hole (FTMH), the macular hole was not closed despite the posterior hyaloid release. The mean pre-treatment best-corrected visual acuity (BCVA) improved significantly from 0.71±0.34 LogMAR to 0.54±0.28 LogMAR after the treatment (p=0.045). The mean central macular thickness (CMT) decreased significantly from 338.46±65.00 ?m to 282.77±62.26 ?m (p=0.013). In the preoperative period, the mean horizontal length of vitreomacular adhesion (HLVMA) was 691.92±268.24 ?m. No correlation was found between HLVMA and release time (p=0.828). No complications were observed. Conclusions: Pneumatic vitreolysis is a relatively safe, minimally invasive and effective treatment option for symptomatic focal VMT syndrome.Öğe Mucormycosis in a Patient with Uncontrolled Diabetes Mellitus(Galenos Yayincilik, 2022) Inal, Mehmet Turan; Memis, Dilek; Hanci, Pervin; Gunbay, Gokhan; Keles, Samet; Mert, Habibe Tulin Elmaslar; Garip, RuveydeMucormycosis; is a rapidly progressive fungal infection due to filamentous fungi of the mucoraceae family. In this case report, we aimed to present the diagnosis and treatment modalities of a patient who developed rhinoorbital mucormycosis. A 54-year-old patient with a history of hypertension applied to the emergency department with a complaint of wound in the mouth that started four days ago. In the examinations performed here, the patient was diagnosed with diabetic ketoacidosis. In the examination of the patient, it was found that there was a necrotic wound on the left hard palate, a necrotic wound extending from the left inferior turbinate to the nasopharynx, and hyphae in the nasal passage. The patient underwent an aggressive debridement operation on the third day, due to the growth in the fungal culture. In the following clinical examination of the patient, ketone in the urine became negative, and his acidosis status improved. On the same day, the patient was treated with a positive coronavirus disease-2019 (COVID-19) polymerase chain reaction. After 15 days of treatment, the patient died due to COVID-19 pneumonia. Mucormycosis should be doubtful in patients presenting with uncontrolled diabetes mellitus and severe sinoorbital infection. All physicians following diabetic ketoacidosis should be vigilant against this rapidly progressing disease with high mortality.Öğe NATURAL COURSE OF VITREOMACULAR TRACTION IN EYES WITH DIABETIC RETINOPATHY AND FACTORS ASSOCIATED WITH SPONTANEOUS RELEASE(Lippincott Williams & Wilkins, 2021) Garip, Ruveyde; Cinar, Ayca Kupeli; Cinar, Abdulkadir Can; Gurlu, VuslatPurpose: The aim of this study was to determine the natural course of vitreomacular traction (VMT) in patients with diabetic retinopathy and to evaluate the factors associated with VMT relief. Methods: Seventy-four eyes of 65 patients with VMT accompanying diabetic retinopathy were evaluated retrospectively. The presence of intravitreal injection and the presence of panretinal photocoagulation were obtained from the medical records of the patients. Spontaneous release of VMT, the horizontal length of vitreomacular traction, the presence of hyperreflective retinal spots, the presence of the epiretinal membrane, and the grade of VMT were evaluated from the spectral-domain optical coherence tomography images. Factors associated with the spontaneous release of VMT were evaluated by logistic regression analysis. Results: Spontaneous release was observed in 28 eyes (37.8%). The horizontal length of VMT was lower in the release of the VMT group compared with the persistent VMT group (P = 0.03). The persistent VMT group had a higher rate of hyperreflective retinal spots and epiretinal membrane compared with the release of the VMT group (respectively; P = 0.003 and P = 0.031). No statistically significant difference was observed between the release of VMT and persistent VMT groups in terms of intravitreal injection and panretinal photocoagulation treatment (respectively; P = 0.938 and P = 0.36). The absence of hyperreflective retinal spots was the most important prognostic factor for the spontaneous release of VMT (P = 0.029). Conclusion: Spontaneous release of VMT observed higher rates of patients without hyperreflective retinal spots, epiretinal membrane, and patients with lower horizontal length of VMT.Öğe Prognostic factors associated with the course of vitreomacular traction in eyes with age-related macular degeneration(Elsevier, 2022) Garip, Ruveyde; Cinar, Ayca K.; Cinar, Abdulkadir C.; Sakallioglu, Ahmet Kursad; Guclu, Hande; Gurlu, VuslatClinical relevance: Vitreomacular traction(VMT) is a clinical syndrome that can cause decreased vision and may affect the treatment response in cases of age-related macular degeneration(AMD). Factors affecting the course of VMT in AMD cases will guide the clinician in terms of patient management.Background: The aim of this study was to determine the prevalence of VMT in patients with AMD, to evaluate the natural course of VMT, and to investigate factors associated with the prognosis of VMT in eyes with AMD.Methods: This retrospective case series was conducted with 55 eyes of 46 patients who were diagnosed as having AMD accompanying with VMT. Demographic data, complete ophthalmologic examination findings, type of AMD, receiving an intravitreal injection(IVI), number of IVIs, and the presence of complete spontaneous release were obtained from the medical records of the patients. The horizontal length of VMT(HLVMT), central macular thickness(CMT), the horizontal length of choroidal neovascularization(HLCNV) were evaluated from spectral -domain optical coherence tomography(SD-OCT) images.Results: Spontaneous release was observed in 7(28%) eyes of the exudative AMD group and 10(33.3%) eyes of the nonexudative AMD group. On the last visit, the HLVMT was increased in 22(40%) of the eyes and a decrease in HLVMT was observed in 8(14.5%) of the eyes. In the remaining 12(21.8%) eyes had unchanged HLVMT. In all eyes with CNV, the area of VMT corresponded in 100% with localization of the CNV complex. No significant difference was found between the eyes with spontaneous release and persistent traction in terms of the type of AMD, IVI, HLVMT, age, gender, and crystalline lens status. Conclusion: In this study, VMT was observed at higher rates in eyes with exudative AMD compared to the eyes with nonexudative AMD. However, spontaneous release rates were found close to those with idiopathic VMT independently of the type of AMD, HLVMT, and IVI.Öğe The reliability of trabeculectomy surgical videos on the internet for educational purposes in the changing world(Royal College Surgeons Edinburgh, 2022) Sakallioglu, Ahmet Kursad; Garip, RuveydeBackground and purpose of the study: The use of social media that facilitates access to surgical training is increasing among general practitioners/surgeons. The present study aimed to evaluate the educational quality of videos on social media and the medical education websites in terms of trabeculectomy surgery.Methods: In this cross-sectional and register-based study, the term trabeculectomy has been searched on 22 websites containing medical surgery training videos. Demographical features and descriptive statistics of videos are noted. All videos were evaluated independently by two ophthalmologists according to DISCERN, Journal of American Medical Association, and Global Quality scoring system. The main 11 steps of trabeculectomy surgery were taken into consideration in each video and Video Quality Score was determined based on these steps.The main findings: In total, 731 videos were watched and 634 were excluded and 97 videos were included in the study. The total quality of all videos according to DISCERN, JAMA, GQS, and VQS scores were 31.6 +/- 9.1 (poor quality), 1.3 +/- 0.4 (poor quality), 2.6 +/- 0.9 (fair quality), and 6.9 +/- 2.1 (poor quality) respectively. Only 6 of the 97 evaluated videos included all the steps of trabeculectomy surgery. Videos have longer duration, videos with narration or videos with descriptive subtitles were found to be significantly higher quality than those are not.Conclussion: The educational quality of internet videos may be far from the quality it should be and it is indisputable that it is necessary to be able to access surgical educational videos that are peer-viewed and whose quality is not doubted.(c) 2021 Published by Elsevier Ltd on behalf of Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.Öğe The role of inflammatory biomarkers in predicting primary acquired nasolacrimal duct obstruction and postoperative recurrence(Nagoya Univ, Sch Med, 2023) Garip, Ruveyde; Sakallioglu, Ahmet KursadThis study aims to determine the relationship between systemic inflammatory biomarkers and primary acquired nasolacrimal duct obstruction and to evaluate whether they can be used as indicators in determining the risk of recurrence after dacryocystorhinostomy. This retrospective, comparative case series was conducted with 57 primary acquired nasolacrimal duct obstruction patients and 58 age-and gender-matched controls. All subjects underwent a complete ophthalmologic examination and complete blood count measurements. The mean neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammation index were significantly higher in patients with primary acquired nasolacrimal duct obstruction (p = 0.005, p = 0.01, and p = 0.003, respectively). In recurrent patients, the neutrophil-to-lymphocyte ratio was significantly higher than in those who did not develop a recurrence (p = 0.029). The area under the curve was determined as 0.775 (p = 0.029) for the neutrophil-to-lymphocyte ratio in predicting recurrence. The neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammation index levels were significantly higher in patients with primary acquired nasolacrimal duct obstruction compared to healthy controls. The neutrophil-to-lymphocyte ratio might be used as a simple and inexpensive indicator for predicting recurrence in patients with primary acquired nasolacrimal duct obstruction.Öğe What Hundreds of Millions of Patients With Dry Eye Will Find on YouTube: A Quality and Reliability Research of the YouTube Videos(Lippincott Williams & Wilkins, 2022) Sakallioglu, Ahmet Kursad; Garip, RuveydePurpose: The aim of this study was to evaluate the demographic features, quality, and reliability of YouTube videos addressing dry eye disease (DED). Methods: The term dry eye disease has been searched on YouTube. The first 500 videos that emerged using the defined search term were evaluated. Duplicated-split videos, videos shorter than 60 seconds, videos with a language other than English or videos with an unintelligible English accent, and videos unrelated to DED were excluded. Video uploaders, types, origins, durations, and viewer interactions of the videos were noted. DISCERN, the Global Quality Score, and the Video Quality Score (created by the authors) were used to evaluate the video quality. Results: Of the 500 videos, 262 videos were excluded, and the remaining 238 videos were evaluated. Videos were of moderate quality on all 3 scoring systems. The medical institute and academic society videos had the highest quality (P < 0.05). The quality of videos uploaded by physicians was significantly lower than medical institute and academic society videos and was higher than the others (P < 0.05). User interactions and video duration were weakly positively correlated with the video quality (P < 0.05). Conclusions: Among YouTube videos on DED, only a minority are of good or excellent quality. Videos uploaded by medical institutes or academic societies scored higher in quality than those uploaded by physicians, which, in turn, scored higher than those uploaded by all others. User interactions were weakly correlated with quality values, suggesting user interactions are not good indicators of the quality of YouTube videos on DED.
