Purpose: To investigate platelet-to-lymphocyte ratio (PLR) in retinal vein occlusion (RVO) patients. Methods: In this study, we retrospectively reviewed data of 32 patients with RVO (RVO group) and 32 age- and sex-matched participants without RVO (control group) between January 2017 and March 2019. The PLR was determined by dividing the platelet count by the lymphocyte count. Results: Age and gender were comparable between the groups ( p = 0.204 and p = 0.800, respectively). PLR was significantly elevated in the RVO group compared with the control group (137 (113–164) vs 101 (86–129), p = 0.001)). In the receiver operator characteristics curve analysis, the optimal cut-off value of PLR for predicting RVO was 123, with 69% sensitivity and 72% specificity. Conclusion: We report that PLR are elevated in RVO, suggesting that PLR may be a useful marker for RVO.

Objective:To evaluate the physiologic changes in intraocular pressure associated with pregnancy in healthy Syrian refugee women in Turkey.Materials and Methods:In this cross-sectional study, intraocular pressures were measured using a Goldmann tonometer in 235 patients in the first, second, and third trimester of pregnancy and puerperium among Syrian refugees in Turkey.Results:Mean intraocular pressures values of the right eye were 15.5±2.5 mmHg, 14.4±1.4 mmHg, 13.9±1.6 and 14.7±1.9 mmHg in the three trimesters and puerperium, respectively. Mean intraocular pressures values of the left eye were 15.3±1.6 mmHg, 14.3±1.4 mmHg, 13.9±1.6 and 15.3±2.2 mmHg in the three trimesters and puerperium, respectively. The mean intraocular pressures values measured from both eyes were significantly higher in first trimester and puerperal period than in the third trimester (p<0.001).Conclusion:Changes in the intraocular pressure in pregnancy are common and temporary. This study shows the baseline changes in the intraocular pressure during pregnancy in healthy women. Therefore, we cannot extrapolate the results to the whole eye. A decrease in intraocular pressures was shown in healthy pregnant women.

Silicone-hydrogel (SiH) contact lenses are frequently used as a bandage after anterior segment surgical procedures. Several types of lenses may exhibit clinical performances with different characteristics. This study aims to evaluate the efficacy of two SiH contact lenses following corneal crosslinking (CXL). Forty-nine keratoconus patients scheduled for consecutive CXL surgery in both eyes were included in this comparative, double-blind, prospective study. A Balafilcon A

Objective: To compare clinical outcomes of cataract surgeries with 2.4 mm and 2.8 mm clear corneal incisions. Materials and Methods: This retrospective study comprised 2 groups of cataract surgery cases with different wound lenghts of group 1; 2.4 mm and group 2; 2.8 mm. We evaluated 80 eyes of 72 patients with 3-month follow-ups. Procedures carried out using the temporal self-sealing incision technique. Measured intraoperative parameters included phacoemulsification time, mean cumulative dissipated ultrasound energy and total volume of balanced salt solution used. Keratometric data, specular microscopy and macular thickness were measured preoperatively, and postoperative 1 and 3 months. Vector analysis calculated the surgically induced astigmatism. SPSS 15.0 were used for statistical analysis. Results: There were no significant differences in intraoperative ultrasound energy, total phacoemulsification time and volume of balanced salt solution analyzed between two groups (p>0.05). There were no statistically significant difference between two groups in macular thickness alteration and endothelial cell loss (ECL) (p>0.05). The mean surgically induced astigmatism was significantly less in group 1 in each visit (p<0.05). Conclusion: Phacoemulsification surgery through a 2.4 mm incision size appeared to be safe and less surgically induced astigmatism.
