PURPOSE To evaluate the oxidative stress status and anti-oxidative defence in patients with age-related macular degeneration (AMD). METHODS A total of 22 patients diagnosed with AMD and 23 age-matched healthy controls were included in the present study. Serum levels of total oxidant status (TOS), total antioxidant status (TAS), total thiol status (TTS)(More)
AIM Investigating the retinal nerve fiber layer (RNFL), macular and ganglion cell complex thickness in eyes of migraine patients using optical coherence tomography. METHODS The study was designed as an observational cross-sectional study. 50 patients with migraine (30 patients with aura and 20 patients without aura) and 50 healthy volunteers were(More)
BACKGROUND Because hyperglycemia-induced oxidative stress may be a cause of retinopathy, this study examined the hypothesis that administration of exogenous antioxidants, stobadine (ST) and vitamin E (vitE), can restore retinal abnormalities in experimental diabetes. METHODS Normal and streptozotocin (STZ)-induced male Wistar rats received daily intraoral(More)
PURPOSE We investigate changes in macular choroidal thickness in eyes without diabetic retinopathy of patients with various durations of diabetes, using enhanced depth imaging optical coherence tomography (EDI OCT). METHODS The 134 Type-2 diabetic patients who presented without diabetic retinopathy were prospectively imaged using EDI OCT on Heidelberg(More)
OBJECTIVE Endothelial dysfunction plays an important role in the development of diabetic retinopathy. The aim of this study was to evaluate endothelial dysfunction using different approaches in patients with type 1 diabete mellitus with early stages of diabetic retinopathy. For this purpose, we investigated the serum levels of cellular adhesion molecules,(More)
PURPOSE Topical steroid use is usually avoided in cases of corneal epithelial defect. We evaluated the effect of topical steroid treatment on corneal epithelial healing after epithelial debridement in vitreoretinal surgery. METHODS Our study population included 85 eyes undergoing vitreoretinal surgeries in our clinic. We prospectively compared the(More)
PURPOSE We aimed to evaluate the dynamic function of iris muscle in asymmetric pseudoexfoliation patients by videonystagmography. METHODS 15 patients with asymmetric pseudoexfoliation and 15 control subjects were included. The function of iris muscle was assessed by the pupillometry test of the videonystagmography by calculating the percent of change in(More)
