BACKGROUND AND OBJECTIVE To evaluate the intrasession reproducibility of the peripapillary retinal nerve fiber layer (RNFL) thickness measurements obtained by spectral-domain optical coherence tomography (SD-OCT) in eyes with keratoconus and normal eyes. PATIENTS AND METHODS Peripapillary RNFL thickness measurements with SD-OCT were repeated three times during the same visit using the eye tra...

The aim of this study is to investigate early findings of the choroidal effusion induced by topiramate use which is thought to be responsible for bilateral acute angle closure glaucoma. Enhanced depth imaging (EDİ) spectral domain optical coherence tomography (SD-OCT) recordings of 34 patients who has been used topiramate for the prophylaxis of migraines, before and after 2 weeks of drug use we...

Purpose To investigate radial peripapillary capillary (RPC) network in patients affected by retinitis pigmentosa (RP). Methods Eleven patients (22 eyes) with previous diagnosis of RP and 16 age-matched healthy subjects (16 eyes) were enrolled. The diagnosis of RP was made based on both clinical features and electrophysiological examination. All patients underwent a complete ophthalmologic exa...

PURPOSE To determine the interocular retinal nerve fiber layer (RNFL) thickness difference of normal subjects. METHODS Both eyes of 230 normal adults received peripapillary RNFL thickness measurements using OCT. The effect of ocular cyclotorsion on the RNFL thickness profile was mathematically corrected. The fractional and absolute interocular RNFL thickness differences at 256 points of perip...

OBJECTIVE To assess optical coherence tomography in differentiating optic disc edema (ODE) due to papilledema and other optic neuropathies from optic nerve head drusen (ONHD). METHODS Optical coherence tomographic images from 60 subjects (20 with ODE, 20 with ONHD, and 20 control subjects) were assessed qualitatively and quantitatively. Qualitative criteria for ODE included an elevated optic ...

PURPOSE This pilot study investigated whether high-resolution spectral-domain optical coherence tomography (SD-OCT) could detect differences in inner retinal layer (IRL), peripapillary retinal nerve fiber layer (RNFL), and macular thickness between patients with Parkinson's disease (PD) and controls. METHODS Both eyes of patients with PD and age-matched controls were imaged with the Heidelber...

INTRODUCTION To evaluate the relationship between retinal nerve fiber layer (RNFL) thickness measured by Cirrus high-definition (HD) optical coherence tomography (OCT) and the axial length and refractive error of the eye. MATERIALS AND METHODS A total of 100 eyes of 100 healthy subjects (age 20-34 years with M/F ratio of 57/43), comprising 50 eyes with emmetropia [spherical equivalent (SE) 0 ...
