purpose: to evaluate the effects of smoking on the central corneal thickness (cct). methods: in a historical chohort analytic study, referred cases have been divided into two groups (cigarette smokers, and non–cigarette smokers).  laboratory tests including fasting blood sugar (fbs), blood urea nitrogen (bun); and blood pressure were checked. complete eye examination was performed. cct was meas...

PURPOSE To evaluate the macular thickness changes in diabetic macular edema after meal. METHODS In this prospective case series, macular thicknesses of diabetic patients with clinically significant macular edema (CSME) were measured after 7 h of fasting and repeated 2 h after breakfast. RESULTS Thirty six eyes of 20 diabetic patients were evaluated. The mean central subfield thickness (CST)...

BACKGROUND The purpose of this study was to evaluate nepafenac ophthalmic suspension 0.1% (Nevanac(®); Alcon Research Ltd) in the prevention of macular edema following cataract surgery in diabetic retinopathy patients. METHODS This was a multicenter, randomized, double-masked, vehicle-controlled study of 263 adult diabetic patients with nonproliferative diabetic retinopathy requiring cataract...

PURPOSE To assess the effectiveness and safety of intravitreal ranibizumab compared with bevacizumab for the treatment of macular edema associated with branch retinal vein occlusion (BRVO). METHODS This was a retrospective study of 80 eyes with macular edema associated with BRVO. Patients received either 0.5 mg of ranibizumab (n = 24) or 1.25 mg of bevacizumab (n = 56) intravitreally. Both gr...

purpose: to evaluate corneal thickness changes after soft contact lens (scl) removal in lasik candidates. methods: fifty lasik candidates (100 eyes) with history of daily wear scl for at least 6 months were enrolled in this descriptive study. central corneal thickness was measured by ultrasonic pachymetry immediately after lens removal and then repeated daily at the same time, until the thickne...

PURPOSE To explore the correlation between outer retinal substructures and visual acuity in dry age-related macular degeneration (AMD). METHODS Analysis of spectral domain optical coherence tomography datasets from 100 eyes of 100 consecutive patients with dry AMD was performed. The internal limiting membrane, outer nuclear layer (ONL), external limiting membrane (ELM), inner segment-outer se...

PURPOSE To estimate genetic influences accounting for macular thickness in the Korean population. METHODS Study subjects were 830 healthy Korean adults (117 monozygotic twin pairs and 523 family members) from the Healthy Twin study. Macular thickness was measured with optical coherence tomography for nine subfields including the fovea, four inner quadrants (within 1 to 3 mm of the center), an...

purpose : to evaluate central corneal thickness (cct) in patients with juvenile glaucoma and compare it with that of normal individuals methods : a prospective, case-control study was performed on 80 eyes with juvenile glaucoma who attended glaucoma clinic in farabi eye hospital, tehran, iran and 107 clinically normal healthy eyes. standard automated perimetry (sap) was performed for all the pa...

PURPOSE To show a case in which the shape of the fovea changed after an asymptomatic macular posterior vitreous detachment (PVD). METHODS The foveal shape was determined from the spectral-domain optical coherence tomography (OCT) images before and after a spontaneous macular PVD. RESULTS A 66-year-old man with a unilateral macular hole in the right eye presented with a perifoveal PVD in the...

Purpose To quantify macular vascular density using optical coherence tomography angiography (OCTA) and to investigate its relationship with retinal thickness in myopic eyes of young adults. Methods In this cross-sectional study, 268 myopic eyes without pathological changes were recruited and divided into three groups: mild myopia (n = 81), moderate myopia (n = 117), and high myopia (n = 70). ...
