OBJECTIVE The exact pathogenic mechanism underlying the thrombotic tendency in retinal vein occlusion (RVO) is still not fully established. We investigated relationship between platelet indices including mean platelet volume (MPV) and platelet count in RVO patients compared to control group. PATIENTS AND METHODS Forty six patients (19 female, 27 male)(More)
PURPOSE To investigate the effect of short-term brinzolamide application on human central corneal thickness (CCT). METHODS Seventeen eyes of 16 patients who underwent neodymium:YAG laser posterior capsulotomy were included in the study group. Twenty-two subjects served as controls. Brinzolamide twice daily and fluorometholone four times daily were(More)
A 43-year-old woman presented with a visual acuity of 1/10 in the right eye and 3/10 in the left eye. Ophthalmologic examination disclosed optic disc swelling on both sides with mild nonproliferative diabetic retinopathy. The pupils were equal and reactive without an afferent pupillary defect. Visual field testing showed no significant defect in both eyes.(More)
BACKGROUND Mini-mental state exam (MMSE) was used several times but no study has examined cognition on the Montreal Cognitive Assessment (MoCA) in diabetes and diabetic retinopathy (DR). In this study, we compared MMSE with MoCA in patients with DR and searched for an association between the severity of DR and cognitive impairment (CI). METHODS This(More)
PURPOSE To determine the effect of intravitreal bevacizumab on retrobulbar blood flow of patients with diabetic macular edema. METHODS Peak systolic velocity, end-diastolic velocity, resistance, and pulsatility indices of central retinal artery (CRA), nasal posterior ciliary artery (NPCA), temporal posterior ciliary artery (TPCA), and ophthalmic artery(More)
The aim of this study was to evaluate plasma adropin levels in patients with pseudoexfoliation (PEX). This retrospective case–control study included 35 patients with PEX and 35 individuals without PEX who served as controls. Plasma adropin levels with triglycerides, total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and(More)
Objective: To investigate the retinal nerve fiber layer (RNFL) thickness in essential tremor (ET). Methods: Twenty-seven eyes of 27 patients with essential tremor were included in this study. Twentyseven eyes of 27 healthy volunteers served as controls. All eyes were examined with spectral domain optical coherence tomography (OCT) (Retinascan Advanced(More)
Aim. To describe a case of branch retinal artery occlusion following dental extraction and to point out the ophthalmic complications of dental procedures to ophthalmologists and dentists. Case.
