The aim of this study was to evaluate the prevalence of dry eye symptoms among lecturers. Materials and Methods: The study included 254 lecturers employed at Mersin University. The lecturers were selected by simple random sampling from lists obtained from the personnel department. Data were obtained between November 15 and December 15, 2017 using a questionnaire developed by the researchers and the Ocular Surface Disease Index (OSDI). The data were evaluated using descriptive statistics, Student's t-test, ANOVA, and correlation tests with the SPSS package program. Results: Of the lecturers who participated in the study, 52.8% were male and 47.2% were female, and the mean age was 39.29±9.41 years. According to OSDI scores, 20.5% of the participants had mild, 15% had moderate, and 36.5% had severe disease. There were significant differences in mean OSDI score based on sex (p<0.001), alcohol use (p=0.01), continuous drug use (p=0.03), wearing glasses (p=0.04), history of dry eye (p<0.001), and presence of dry eye symptoms (p<0.001). There were also significant differences between the OSDI score categories in terms of sex (p<0.001), smoking status (p=0.04), wearing glasses (p=0.03), history of dry eye (p<0.001), and presence of dry eye symptoms. The only factor significantly correlated with OSDI score was daily duration of computer usage (p=0.009). Conclusion: Our study showed that a substantial proportion of lecturers experience dry eye symptoms, and OSDI scores were associated with daily duration of computer use. Determining the factors associated with dry eye is important for the planning of preventive interventions.

Objectives: To identify the prevalence of findings in optical coherence tomography (OCT) sections before intravitreal anti-VEGF treatment in patients with diabetic macular edema (DME), and to evaluate the relationship between these findings and final visual acuity and number of injections. Materials and Methods: This retrospective study included 296 eyes of 191 patients (104 male, 87 female) who started intravitreal ranibizumab treatment after being diagnosed with DME in the retina unit between January 2013 and April 2017 were included the study. Spectral domain OCT findings at the time of presentation such as presence of serous macular detachment (SD), vitreomacular traction (VMT), and epiretinal membrane (ERM) were recorded. In addition, the regularity of the ellipsoid zone (EZ) and inner retinal layers was also studied. Results: The mean central retinal thickness measured in SD-OCT was 449±81 μm before treatment and 350±96 μm after treatment (p<0.001). SD was detected in 155 eyes (52.4%), ERM in 67 eyes (22.6%), and VMT in 9 eyes (3%). Thirty eyes (10.1%) had disorganization of the retinal inner layers (DRIL) and 54 eyes (18.2%) had EZ deterioration. The presence of ERM, EZ irregularity, and DRIL were associated with significantly lower final visual acuity (p<0.0001), while there was no relationship between pre-treatment SD and final visual acuity (p=0.11). Injection number was higher in eyes with SD and ERM compared to those without, but this difference was statistically significant only in the presence of SD (p=0.01 and p=0.59, respectively). There was no difference in injection number according to EZ irregularity or presence of DRIL. Conclusion: The coexistence of SD with DME was associated with increased need for treatment but not with final visual acuity. EZ irregularities, DRIL, and ERM are findings that negatively affect visual acuity.

A 14-year-old boy with sickle cell disease presented with preseptal cellulitis findings as proptosis, eyelid edema, and hyperemia. His best corrected visual acuity in the right eye was 20/20 and 16/20 in the left eye. He had limited ductions in vertical and lateral gazes in both eyes. Bilateral venous tortuosity was observed in posterior segment examination. Orbital bone infarction and subperiosteal hematoma were seen in magnetic resonance imaging. He was diagnosed as having orbital compression syndrome secondary to vaso-occlusive crisis of sickle cell disease and was treated with intravenous ampicilin-sulbactam and methylprednisolone.

The modified Z-suture technique is simple, fast, and was determined to be safe in terms of complications. However, long-term outcomes should be evaluated in larger patient groups.

To compare the learning curves of the specialists in two different fields without previous endoscopic endonasal dacryocystorhinostomy experience as well as to reveal the related complications with surgical success rates. Methods: We retrospectively investigated 90 patients who received consecutive endoscopic endonasal dacryocystorhinostomy with mucosa preservation by an ophthalmologist (Group 1, n=45) and an otorhinolaryngologist (Group 2, n=45) between October 2017 and October 2019. Patients who were admitted with epiphora complaints and diagnosed with primary acquired nasolacrimal duct obstruction through lacrimal irrigation test and aged >18 years with at least 6 months of follow-up were included in the study. In all cases, additional pathologies such as septum deviation were evaluated by performing maxillofacial imaging. Patients' medical records were evaluated in terms of surgery duration, complications, and functional achievements. Results: The mean surgical duration of the patients in Group-2 was 36.27 ± 11.61 min, while it was 43.62 ± 16.89 min in Group-1; the difference was statistically significant (p=0.018). Functional achievements in Group 1 was 84.4% (73.3% in the first set of 15 cases, 93.3% in the last set of 15 cases) in Group 2; this rate was 88.9% (80% in the first set of 15 cases, 93.3% in the last set of 15 cases), and the difference was not statistically significant (p=0.53). Septum intervention in addition to endoscopic surgery in both the groups (p=0.03, p=0.005, respectively) and intense bleeding during surgery (for both the groups, p<0.0001) significantly decreased the functional success. Conclusion: Endoscopic endonasal dacryocystorhinostomy, performed after the necessary training, can provide high success and low complication rates when even conducted by ophthalmologists who are unfamiliar with endoscopic surgery after an experience of 30 cases.
