PURPOSE To investigate corneal healing and the factor(s) possibly responsible for refractive changes after laser in situ keratomileusis (LASIK). METHODS Twenty eyes of 10 patients who underwent LASIK for myopia were examined clinically and by real-time confocal microscopy for 6 months. Epithelial and posterior stromal thicknesses and the thickness of the keratocyte activation zone were measur...

PURPOSE: To evaluate the correlation between automated achromatic perimetry (AAP) and the output of two retinal nerve fiber layer (RNFL) analysers: scanning laser polarimetry (GDx-VCC) and optical coherence tomography (OCT). METHODS: Quantitative RNFL measurements with GDx-VCC and Stratus-OCT were obtained in one eye from 52 healthy subjects, 38 ocular hypertensive (OHT) patients and 94 glaucom...

PURPOSE To compare the macular and nerve fiber layer thicknesses as measured by optical coherence tomography (OCT) in amblyopic and fellow eyes. METHODS Fifty patients with monocular strabismic (n = 25) or anisometropic (n = 25) amblyopia (best corrected visual acuity (BCVA) ranging from 20/40 to 20/400) were included in a prospective cross-sectional descriptive study. A refractive error more...

Purpose: We aimed to compare the retinal nerve fiber layer, ganglion cell layer, inner plexiform layer, and the choroid thickness between patients with Behcet disease and healthy subjects by using spectral domain optical coherence tomography (SD-OCT). Methods: Ninety eyes of 45 healthy subjects and 104 eyes of 52 patients with Behcet disease were included in this study. Rheumatoid factor and ...

PURPOSE To measure the retinal nerve fiber layer thickness in patients with pigment dispersion syndrome (PDS) using scanning laser polarimetry and to compare these measurements with those of normal subjects and patients with pigmentary glaucoma (PG). METHODS Age-, sex-, and refractive error-matched subjects--18 patients with PDS, 18 patients with PG, and 20 healthy subjects--were evaluated by...

A histochemical staining technique for cholinesterase is reported for the study of corneal nerves in whole-thickness rabbit cornea. The technique is relatively simple, yields reproducible results, allows good definition of the nerve fiber pattern, and provides the investigator, using a binocular microscope, with the advantage of three-dimensional study. When tissue is stained for specific choli...

PURPOSE To investigate retinal changes prior to vascular signs in patients with type 2 diabetes without diabetic retinopathy or with mild non proliferative diabetic retinopathy. METHODS A cross-sectional study was performed in three groups: patients without diabetes, patients with type 2 diabetes without diabetic retinopathy, and patients with diabetes with mild diabetic retinopathy. Analysis...

BACKGROUND The purpose of this study was to investigate the correlations between microcirculation in the optic disc, average peripapillary retinal nerve fiber layer thickness cupping parameters, and visual field defects in glaucoma patients with the generalized enlargement disc type. METHODS A total of 38 eyes from 38 glaucoma patients with the generalized enlargement disc type were included....

purpose: to evaluate the correlation between retinal nerve fiber layer (nfl) thickness and visual field parameters in patients with optic atrophy. methods: this study was performed on 35 eyes of 28 patients with optic atrophy. nfl thickness was measured by optic coherence tomography (oct) and visual field analysis was performed by humphrey perimetry. the correlation between nfl thickness and vi...
