To investigate retinal and optic disc microvascular alterations using optical coherence tomography angiography (OCTA) in women with polycystic ovary syndrome (PCOS). Forty-six eyes of 23 patients with PCOS (PCOS group), and 50 eyes of 25 sex and age-matched healthy controls (control group) were included in this cross-sectional study. Foveal retinal thickness, peripapillary retinal nerve fiber layer (RNFL) thickness, vessel density in different sections of the retina and optic disc were analyzed by OCTA. The superficial parafoveal vessel densities were significantly lower in PCOS group compared to the control group (53.7 ± 4.0%, and 55.4 ± 2.7%, respectively, p = .02). The deep retinal vessel densities, foveal retinal thicknesses and RNFL thicknesses, whole image of optic disc radial peripapillary capillary densities, foveal avascular zone and flow areas were similar between the groups (p > .05 for all). OCTA analysis indicates that patients with PCOS tend to have lower superficial parafoveal vessel densities.

Purpose: To investigate the influence of topical cyclopentolate 1%, as an anti-muscarinic mydriatic agent, on the peripapillary and macular microvasculature by optical coherence tomography angiography (OCT-A) in healthy adults. Methods: A total of 41 healthy adults without any systemic or ocular disease were enrolled for this prospective consecutive study. All patients underwent OCT-A measurements (OptoVue Inc., Freemont, CA, USA) to assess optic disc status for radial peripapillary capillary network (whole image, inside disc, and peripapillary capillary densities), and superficial and deep capillary plexus whole, foveal, parafoveal and perifoveal densities, and foveal avascular zone (FAZ) densities. Foveal retinal thicknesses and all quadrant retinal fiber layer thicknesses were also assessed. The 4.5 mm × 4.5 mm peripapillary and 6 mm × 6 mm macular OCT-A images were undertaken before and 30 min after instillation of topical cyclopentolate 1% to the right eyes. Results: The mean age of subjects was 38.14 ± 14.10 years. All macular, optic disc, and FAZ densities, foveal retinal thicknesses, average, and all quadrant retinal fiber layer thicknesses were statistically similar between baseline and after administration of topical cyclopentolate 1% (P > 0.05). Conclusion: The current study demonstrated that pupillary dilation with topical cyclopentolate 1% seems to have no statistical effect on macular and peripapillary OCT-A measurements of healthy adults.

This study aimed to evaluate the demographic and clinical features of eye injury cases in the Syrian Civil War. A total of 224 eyes of 212 Syrian patients who were referred urgently to Hatay Mustafa Kemal University Faculty of Medicine Department of Ophthalmology between January 2011 and December 2018 were evaluated retrospectively. Types of trauma and clinical findings were analyzed. Patients were predominantly male (n=194, 91.5%). The mean age was 29.50±10.76 (range 1-74) years. A total of 30 (14.15%) patients were <18 years old. Most eye traumas (n=177, 79.0%) were open globe injuries, and the remaining 21.0% (n=47) were closed globe injuries. Intraocular foreign body was detected in 106 (47.32%) eyes. Primary repair was performed in 74.10% (n=166) of the cases, and evisceration was performed in 4.46% (n=10). Our study indicated that war conditions can cause serious eye injuries in civilians. These conditions often cause vision and eye loss in adults and children. In addition, all units carrying and treating patient should be strongly coordinated to minimize vision, time, and economic losses.
