RESUMO
PURPOSE: To share the anatomical results and visual outcomes of intravitreal gas tamponade combined with laser photocoagulation treatment for optic disc pit maculopathy (ODPM). METHODS: Intravitreal gas tamponade combined with laser photocoagulation treatment was performed on six consecutive patients with ODPM. A 0.3 mL of 100% perfluoropropane (C3F8) gas was injected intravitreally. The patients were then asked to maintain prone position until the C3F8 gas disappeared. Laser photocoagulation was performed the day after the procedure. The outcomes were determined by spectral-domain optical coherence tomography and best-corrected visual acuity (BCVA). RESULTS: In the present study, visual improvement and reduction in serous macular detachment were observed in 83% of the ODPM patients. Complete retinal reattachment was achieved in 66% of the ODPM patients. In one patient, no regression was observed after the repeated treatment, and pars plana vitrectomy was performed. The final BCVA improved in five eyes and unchanged in one eye. No postoperative complications were observed during the follow-up period in any patient. CONCLUSIONS: Intravitreal C3F8 gas tamponade combined with laser photocoagulation procedure is an effective, minimally invasive, and cost-effective treatment method for ODPM.

PURPOSE: To investigate the correlation between the daily relative search volume (RSV) of keywords related to coronavirus and ocular symptoms, and the numbers of the daily coronavirus disease 2019 (COVID-19) new cases and new deaths in Europe using Google Trends (GT). METHODS: The RSVs of the selected keywords related to coronavirus and ocular symptoms between 24 January and 1 June 2020 in the United Kingdom, Spain, Italy, Germany and Turkey were accessed from GT. The numbers of daily COVID-19 new cases and new deaths in the same time interval in the aforementioned countries were compared with the RSVs of the keywords and terms. RESULTS: The United Kingdom, Spain, Italy, Germany, and Turkey were the most affected countries from the COVID-19 pandemic in Europe. In these countries, statistically significant and strong correlations were found between the daily RSVs of most keywords related to coronavirus and ocular symptoms, and the daily numbers of COVID-19 new cases and new deaths ranging from 0.175 to 0.807. CONCLUSIONS: Ocular symptoms are not the frequent signs of COVID-19, but the ocular surface is a possible route for the transmission of COVID-19. The preliminary outcomes of this study demonstrated that there are significant correlations with the ocular symptoms and COVID-19. The news about the relation of eye and COVID-19 in the mass media may have influenced the Google internet search activity of the public for ocular symptoms.

PURPOSE: To investigate microstructural changes in the macular inner retinal layers over time in the fellow eyes of patients with unilateral central retinal artery occlusion (CRAO). METHODS: Spectral-domain optical coherence tomography scans of 16 patients with CRAO were performed at initial examination (1st day), at 1st month, at 3rd month, at 6th month, and the central macular thickness (CMT) and inner retinal layer thicknesses in the fellow eyes of the patients were compared between each visit. The thicknesses of retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), inner plexiform layer (IPL), and inner nuclear layer (INL) were calculated in 9 quadrants according to the definition by the Early Treatment Diabetic Retinopathy Study. RESULTS: CMT decreased over a 6-month period, but the difference was insignificant among visits (p = 0.072). Also, there were no significant differences in the thicknesses of RNFL and GCL among visits (p > 0.05 for all quadrants). But there was thinning in the parafoveal superior and perifoveal superior quadrants of the IPL (p = 0.007, p = 0.01) and in the parafoveal temporal quadrant of the INL (p = 0.033) within 6 months of follow-up in the fellow eyes of the patients with CRAO. CONCLUSION: This study demonstrated subclinical alterations of the macular inner retinal layers over time in the fellow eyes of CRAO patients.

Objectives: The aim of this study was to investigate the frequency of blindness and the pathologies that cause blindness in the Konya province of Turkey. Materials and Methods: The records of individuals over 18 years of age who applied to the health committee of Meram School of Medicine Hospital between January 2015 and December 2018 were evaluated retrospectively. Results: After reviewing the records of 4,268 applicants, a total of 222 applicants were included in the study (159 patients with monocular blindness, 63 patients with binocular blindness). The most common causes of monocular blindness were optic atrophy (13%), amblyopia (11%), and phthisis bulbi (10%). The most common causes of binocular blindness were retinitis pigmentosa (28%), proliferative diabetic retinopathy (13%), and unoperated cataract (11%). The frequency of monocular blindness was 3.7% (95% confidence interval [CI]: 3.2-4.3%) and binocular blindness was 1.5% (95% CI: 1.1-1.9%) in the sample. The frequency of blindness increased with age, with a positive correlation between mean age and blindness (p=0.002). Monocular blind applicants had a significantly lower mean age than binocular blind applicants (48.8±13.3 vs. 55.0±13.1 years, p=0.002) and binocular blind women had a significantly higher mean age than binocular blind men (62.7±16.0 vs. 53.2±11.7 years, p=0.023). The prevalence of monocular and binocular blindness was significantly higher in men than women (p=0.032). Conclusion: The results of this study show that many of the pathologies that cause blindness are preventable or treatable, and that blindness is associated with age.

Purpose: To evaluate the association between monocyte count/high-density lipoprotein (HDL) ratio (MHR) and lymphocyte count/monocyte count ratio (LMR) with pseudoexfoliation syndrome (PEXS) and pseudoexfoliation glaucoma (PEXG).Materials and Methods: A total of 63 participants included in the study. Participants were divided into three groups. Twenty-one patients with PEXS regarded as group 1, 21 patients with PEXG regarded as group 2 and 21 participants without PEXS or PEXG regarded as the control group. Blood parameters were accessed from file records and database retrospectively.Results: The mean MHRs were significantly higher in group 1 and group 2 (p = 0.003, p = 0.036) than the control group, whereas there was no difference between group 1 and group 2 (p = 0.686). The mean LMRs were lower in group 1 and group 2 than the control group but the difference was insignificant (p = 0.232).Conclusion: We found that there is an association between higher MHR and lower LMR with PEXS.

Purpose: The purpose of this article was to evaluate monocyte count and high-density lipoprotein (HDL) cholesterol levels and their ratio (monocyte/HDL ratio [MHR]) in patients with branch retinal vein occlusion (BRVO).Materials and Methods: A total of 50 participants were included in the study. Participants were divided into two groups: Twenty-five patients diagnosed with BRVO and 25 participants as the control group. Ocular examination findings and hematologic parameters were accessed from the file records and database, retrospectively.Results: The mean MHR was significantly higher in BRVO group compared to the control group (13.4 ± 5.2 vs. 8.1 ± 2.2, p < 0.001). In receiver operating characteristics analysis, the area under the curve for MHR was 0.862, and an MHR of >9.5 predicted BRVO with a sensitivity of 76% and specificity of 70.8%.Conclusion: The present study showed that elevated MHR is significantly associated with BRVO. Therefore, MHR may be a useful marker for the emergence of BRVO.

OBJECTIVE: This study aimed to evaluate the frequency and primary causes of blindness in adults aged 18 years and more in Sarikaya rural region of Yozgat, Turkey, to contribute to the epidemiologic information about blindness in our country. MATERIALS AND METHODS: Patients who were examined between October 2016 and March 2017 in Sarikaya State Hospital, Clinic of Ophthalmology, were prospectively investigated. Demographic and ophthalmic examination data, presented visual acuities (VA), primary causes of blindness, and monocular blindness were recorded. Blindness was defined as presented visual acuities (VA) definition of World Health Organization criteria. RESULTS: A total of 3423 participants, aged 18-96 years, were examined. Among them, 1887 participants (55%) were female and 1536 (45%) were male. The frequency of blindness was 1.5% (95% CI: 1.1%-2.0%); and cataract was the primary cause of blindness (42%). Age-related macular degeneration (21%) and uncorrected refractive error (13%) were the next main causes of blindness. The frequency of monocular blindness was 4% (95% CI: 3.8%-5.2%), and cataract (27%) followed by phthisis bulbi/evisceration (13%) and glaucoma (12%) were the leading causes of monocular blindness. CONCLUSION: In this rural region of Central Anatolia, the primary cause of blindness and monocular blindness was an unoperated cataract. The patterns of age-specific causes of blindness are variable, but most of them are avoidable or treatable. Thus, awareness should be increased in societies, and people should be prevented from blindness with health-care programs in rural regions of developing countries.
