multiple sclerosis (ms) is the most prevalent disease caused by the inflammatory demyelinating process that causes progressive nervous system degeneration over the time. optical coherence tomography (oct) is a non-invasive optical imaging technology, which can measure the thickness of retinal nerve fiber layer as well as the diameter of the macula. the purpose of the study is evaluation oct fin...

purpose: to determine peripapillary retinal nerve fiber layer (rnfl) thickness by three-dimensional optical coherence tomography (3d-oct) in a normal iranian population and to evaluate the concordance of these measurements with those obtained by the second generation of optical coherence tomography (oct ii). methods: in a cross-sectional observational study, 96 normal iranian subjects 20-53 yea...

In this retrospective cross-sectional study, we quantitatively analyzed the tomographic features in the neural tissues around the optic disc in patients with diabetic retinopathy with and without panretinal photocoagulation. We analyzed 206 eyes, comprising 33 normal eyes in subjects without diabetes (group I), 30 eyes without diabetic retinopathy (group II), 66 eyes with non-proliferative diab...

PURPOSE To evaluate the retinal nerve fiber layer measurements with time-domain (TD) and spectral-domain (SD) optical coherence tomography (OCT), and to test the diagnostic ability of both technologies in glaucomatous patients with asymmetric visual hemifield loss. METHODS 36 patients with primary open-angle glaucoma with visual field loss in one hemifield (affected) and absent loss in the ot...

purpose: to measure peripapillary retinal nerve fiber layer (rnfl) thickness in normal human eyes by optical coherence tomography (oct). methods: eighty-one eyes of 45 normal participants were studied. each person underwent a complete ophthalmic examinations, including measurement of visual aquity and intraocular pressure and evaluation of the anterior segment, optic disc, and retinal nerve fib...

Introduction The retina may reflect Alzheimer's disease (AD) neuropathological changes and is easily visualized with optical coherence tomography (OCT). Retinal thickness decrease has been correlated to AD, however, without information on amyloid status. We correlated retinal (layer) thickness to AD biomarkers in amyloid-positive early-onset AD (EOAD) patients and amyloid-negative controls. M...

purpose : this study was designed to assess and compare the thickness of the peripapillar retinal nerve fiber layer (rnfl) in amblyopic and normal eyes in unilateral strabismic ambelyopia using scanning laser polarimeter. methods : scanning laser polarimetry was performed on 17 patients with unilateral strabismic amblyopia who had an absence of neurologic diseases or glaucoma with a minimum age...

BACKGROUND We compared the parameters of retinal nerve fibre layer in patients with advanced glaucoma with the use of different OCT (Optical Coherence Tomograph) devices in relation to analogical measurements performed with GDx VCC (Nerve Fiber Analyzer with Variable Corneal Compensation) scanning laser polarimetry. MATERIAL/METHODS Study subjects had advanced primary open-angle glaucoma, pre...

PURPOSE This study was designed to assess and compare the thicknesses of the fovea and the retinal nerve fiber layer in normal children and children with amblyopia. METHODS Optical Coherence Tomography (OCT) was performed on 26 children (52 eyes total) with unilateral amblyopia that was due to anisometropia or strabismus. OCT was also performed on 42 normal children (84 eyes), for a total of ...
