R.-R.O.P. StudyBackground To evaluate the prevalence, risk factors and treatment of retinopathy of prematurity (ROP) in Turkey and to establish screening criteria for this condition. Methods A prospective cohort study (TR-ROP) was performed between 1 April 2016 and 30 April 2017 in 69 neonatal intensive care units (NICUs). Infants with a birth weight (BW)=1500 g or gestational age (GA)<= 32 weeks and those with a BW> 1500 g or GA> 32 weeks with an unstable clinical course were included in the study. Predictors for the development of ROP were determined by logistic regression analyses. Results The TR-ROP study included 6115 infants: 4964 (81\%) with a GA <= 32 weeks and 1151 (19\%) with a GA>32 weeks. Overall, 27\% had any stage of ROP and 6.7\% had severe ROP. A lower BW, smaller GA, total days on oxygen, late-onset sepsis, frequency of red blood cell transfusions and relative weight gain were identified as independent risk factors for severe ROP in infants with a BW=1500 g. Of all infants, 414 needed treatment and 395 (95.4\%) of the treated infants had a BW <= 1500 g. Sixty-six (16\%) of the treated infants did not fulfil the Early Treatment for Retinopathy of Prematurity requirements for treatment. Conclusions Screening of infants with a GA <= 34 weeks or a BW<1700 g appears to be appropriate in Turkey. Monitoring standards of neonatal care and conducting quality improvement projects across the country are recommended to improve neonatal outcomes in Turkish NICUs.Item Structure-Function Mapping Using a Three-Dimensional Neuroretinal Rim Parameter Derived From Spectral Domain Optical Coherence Tomography Volume Scans(ASSOC RESEARCH VISION OPHTHALMOLOGY INC, 2021-01-01) Celebi, Ali Riza Cenk; Park, Elli A.; Vercellin, Alice Chandra Verticchio; Tsikata, Edem; Lee, Ramon; Shieh, Eric; Antar, Hussein; Freeman, Madeline; Zhang, Jing; Que, Christian; Simavli, Huseyin; McClurkin, Michael; Guo, Rong; Elze, Tobias; de Boer, Johannes F.; Chen, Teresa C.Purpose: To assess the structure-function relationship in glaucoma using Humphrey visual field (HVF) perinnetry and a three-dimensional neuroretinal rim parameter derived from spectral domain optical coherence tomography (SD-OCT) volume scans. Methods: Structure-function correlation was analyzed globally and regionally (four quadrants and four sectors). Structural data included peripapillary retinal nerve fiber layer (RNFL) thickness and minimum distance band (MDB) neuroretinal rim thickness, defined as the shortest distance between the inner cup surface and the outer retinal pigment epithelium/Bruch's membrane complex. Logarithmic regression analyses were performed and Pearson correlation coefficients determined to assess relationship strength. Results: The study consisted of 102 open-angle glaucoma patients and 58 healthy subjects. The Pearson correlation coefficient for global MDB thickness (R = 0.585) was higher than for global RNFL thickness (R = 0.492), but the difference was not statistically significant (P = 0.18). The correlation coefficients for regional MDB thicknesses and corresponding HVF sensitivities were higher than those for regional RNFL thicknesses and HVF in six out of eight regions (P = 0.08 to 0.47). In the remaining two out of eight regions, the correlation coefficients were higher for RNFL thickness than for MDB thickness (P = 0.15 to 0.20). Conclusions: Three-dimensional MDB neuroretinal rim thickness relates to visual function as strongly as the most commonly used SD-OCT parameter for glaucoma, two-dimensional peripapillary RNFL thickness. Translational Relevance: This paper illustrates the potential for 3D OCT algorithms to improve in vivo imaging in glaucoma.Item Predictive value of ectopic inner foveal layer without internal limiting membrane peeling for idiopathic epiretinal membrane surgery(SPRINGER, 2022-01-01) Karasu, Bugra; Celebi, Ali Riza CenkPurpose To investigate the clinical importance of ectopic inner foveal layer (EIFL) grading (mild to severe) in patients diagnosed with idiopathic epiretinal membrane (iERM) and had pars plana vitrectomy (PPV) with solely ERM peeling. Materials and methods Patients diagnosed with iERMs who had undergone PPV including only ERM peeling were enrolled in the study, and follow-up findings were recorded at baseline, and at 3, 6, 12 months and final examinations. EIFL was categorized into four grades, from mild to severe. Pre- and postoperative anatomical changes were measured using spectral domain optical coherence tomography (SD-OCT) imaging. The association between EIFL and other SD-OCT parameters with best-corrected visual acuity (BCVA) was assessed before and after PPV surgery. Results One-hundred thirty-eight eyes of 106 patients with mild to severe EIFL were included in the study. Higher EIFL thickness was significantly correlated with lower baseline (r = 0.575, p = 0.020) and final BCVA (r = 0.748, p = 0.001). Although EIFLs continued in advanced-stage cases (stage 3 and 4) (64 eyes {[}82\%]) at the final visit, it was observed in 8 eyes (23\%) in the early stage (stage 2) of iERMs. A strong positive correlation was found between EIFL thickness and recurrence rate of ERM (r = 0.876, p < 0.001). Recurrence of ERM was detected in 27 eyesItem Comparison of success between external and endonasal dacryocystorhinostomy in primary acquired nasolacrimal duct obstruction in Turkish cohort(KARE PUBL, 2020-01-01) Karasu, Bugra; Kiray, Gulunay; Eris, Erdem; Perente, Irfan; Celebi, Ali Riza CenkOBJECTIVE: To evaluate the results and recurrence rates of external and endonasal dacryocystorhinostomy (DCR) surgery in patients with primary acquired nasolacrimal duct obstruction (PANDO) in Turkish Cohort. METHODS: Medical records were reviewed in all patients who underwent surgery for PANDO between January 2010 and September 2014 in a tertiary university hospital retrospectively. The patients were followed up on the first day, first month, third month and sixth month postoperatively. Lacrimal drainage system and recurrence rates were recorded. RESULTS: This study was conducted in 81 patients, 27 of whom were men (33.3\%) and 54 were women (66.7\%). The mean follow-up time was 30.1316.42 months (range 6-62 months). The mean age was 50.51 +/- 12.47 years (range 16 to 77 years). External DCR was used in 44 (66.7\%) of the cases and endonasal DCR was used in 37 (45.7\%) of the cases. Surgical results of DCR were divided into three groups based on the integrity and openness of the lacrimal drainage pathway in all PANDO patients. Operation success rates of these data revealed that 45 (55.6\%) cases were recorded as successful, 20 (24.7\%) of the cases were accepted as partially successful and 16 (19.8\%) of the cases were deemed as unsuccessful. Based on these data, surgical success rates were found in 38 (86.4\%) patients in external DCR and 27 (73\%) patients in endonasal DCR. Surgical failure rates were six (13.6\%) in external DCR and 10 (27\%) in endonasal DCR. There was no statistically significant difference between success rates and recurrences in both groups (p>0.05). CONCLUSION: Endoscopic DCR produced simple, minimally invasive and preferable results compared to external DCR in the Turkish population. Although the success of external DCR is higher and the recurrence is lower than endoscopic DCR, with the outcomes of this study, endoscopic DCR can be tried as the first choice to protect the patient from major surgery and anesthesia in PANDO.Item The role of anterior segment optical coherence tomography in the management of an intra-corneal foreign body(SPRINGER INTERNATIONAL PUBLISHING AG, 2016-01-01) Celebi, Ali Riza Cenk; Kilavuzoglu, Ayse Ebru; Altiparmak, Ugur Emrah; Cosar, C. Banu; Ozkiris, AbdullahIntroduction: Corneal foreign bodies are reported to be the second most common type of ocular injury. Anterior segment optical coherence tomography (AS-OCT) is a valuable tool for the early diagnosis and monitoring the progress of treatment in cases of ocular trauma. Herein we aimed to report on a patient with an intra-corneal foreign body and the role of AS-OCT in management. Case presentation: A 34-year-old male presented with foreign body sensation in his left eye. Slit-lamp biomicroscopic examination revealed a peripherally located intrastromally embedded foreign body with a free anterior edge extending outwards from the cornea. It was not possible to visualize the foreign body's entire route through the cornea because of localized corneal edema. AS-OCT showed shadowing of the corneal layers corresponding to the location of the corneal foreign body. A hyper-reflective lesion was observed close to the inside edge of the foreign body in the cornea, indicating that the foreign body had not completely penetrated the cornea. The foreign body was removed via the external route, as it had not completely penetrated the cornea. During the postoperative period the patient was asymptomatic, although the left eye's cornea healed with scar tissue. Discussion and Evaluation: AS-OCT facilitates non-invasive rapid imaging of ocular tissue at various depths, thereby providing accurate assessment of foreign body characteristics. The location of an intracorneal foreign body and the status of the surrounding ocular structure dictate the optimal surgical technique to be employed. Conclusions: AS-OCT in the present case facilitated localization and determination of the size of a corneal foreign body. In addition, AS-OCT findings assisted in selection of the appropriate surgical intervention.Item Retinal tear: an unusual complication of ocular toxoplasmosis(DE GRUYTER OPEN LTD, 2015-01-01) Celebi, Ali Riza Cenk; Kilavuzoglu, Ayse Ebru; Altiparmak, Ugur Emrah; Cosar, Cemile Banu; Ozkiris, AbdullahPurpose: It is aimed to report on a 16-year-old patient with acquired ocular toxoplasmosis complicated by a retinal tear. Methods: Retrospective medical chart review Results: A 16-year-old Caucasian female presented with vision loss in her right eye. In addition to a white active lesion between the fovea and the optic nerve head, marked vitreous opacification was noted. She was diagnosed with ocular toxoplasmosis. The patient was treated with oral azithromycin, clindamycin, and trimethoprim-sulfamethoxazole. One month later, retinochoroiditis resolved and vitreous cleared. Three months after onset, patient presented with floaters in the right eye and a retinal tear was located at the temporal region of the retina. Prophylactic argon laser treatment that encircled the retinal tear was performed. No other abnormalities were noted during 6 months of follow-up. Conclusions: Retinal tear associated with ocular toxoplasmosis is rareItem Assessment of risk factors on eye dryness in young adults using visual display device in both contact lens wearers and non-wearers(SPRINGER, 2022-01-01) Altinbas, Ekin; Elibol, Alperen; Firatli, Goktug; Ayhan, Cemre; Celebi, Ali Riza CenkPurpose Researchers are interested in examining the impact of visual display devices (VDDs) on the development of dry eye illness because their use is becoming more common among college students. The goal of this study was to see if there was a link between certain risk factors and the development of eye dryness in VDDs using young adults who wore contact lenses and those who did not. Methods The self-administrated survey was hosted in Google Forms, sent via e-mail to the participants. It consisted of two parts of assessing different risk factors (i.e., environmental conditions, angle of gaze, and years of VDD use) with contact lens use and Ocular Surface Disease Index (OSDI) questionnaire. The OSDI scores of the entire sample who suffer from dry eye and the subgroup using contact lenses were calculated. The relationship between different risk factors with the OSDI scores was also assessed. Results A total of 274 young adults from college students and academic staff (216 female, 58 male) were suffering from eye dryness. Eighty-eight of the 274 participants wore contact lenses. The mean OSDI scores of the 274 young adults were 32.92. Mean OSDI scores in contact lens wearers and non-wearers were 34.36 and 32.24, respectively (p < 0.01). There was a statistically significant relationship between OSDI score and indoor environmental conditions in computer using VDD group. Using a computer in a dark environment and above the line of sight resulted in a higher OSDI scores. Females who wore contact lenses while using a computer for more than three years had significantly higher OSDI scores than non-wearer females. Tablet type VDD use increased the mean ODSI scores of the contact lens wearers significantly. Conclusions Dry eye symptoms were shown to be increased in the contact lens wearer group with the increased duration of computer VDD use, decreased indoor environmental brightness conditions, and above the line of sight.
