background: optical coherence tomography (oct) is a simple, high-resolution technique to quantify the thickness of retinal nerve fiber layer (rnfl) and macula volume, which provide an indirect measurement of axonal damage in multiple sclerosis (ms). this study aimed to evaluate oct finding in relapsing-remitting ms patients of the northwest of iran and compare them with a normal control group. ...

Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases.  Furtherm...

purpose: to determine the effect of induced myopia and hyperopia using soft contact lenses on optic disc parameters measured by fourier domain optical coherence tomography (fd-oct) in emmetropic persons. methods: in a quasi-experimental self controlled study, 57 normal emmetropic participants 18-42 years of age were studied. each subject underwent a complete ophthalmic examinations including me...

purpose: to compare peripapillary retinal nerve fiber layer (rnfl) thickness among multiple sclerosis (ms) patients with or without a history of optic neuritis (on) and a healthy control group. methods: in this retrospective case-control study, 59 ms patients were recruited from a neurology clinic of imam hossein hospital. of which, 36 patients had at least one episode of on and 23 others had n...

purpose: to describe the association between optic disc traction and non-arteritic anterior ischemic optic neuropathy (naion). methods: eighty three eyes of 83 patients with naion were evaluated by optical coherence tomography (oct) for detecting vitreous adhesion to the optic nerve head with separation from adjacent retina (partial posterior vitreous detachment). those who were negative for su...

Aim – To compare the results of optic disc analysis using optical coherence tomography, fundus photography and stereoscopic biomicroscopy. Materials & Methods – A comparative, observational case series and interobserver variability study in which 2 groups of patients were analysed by all the 3 methods. One group had primary open angle glaucoma patients and the other group were patients undergoi...

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...

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 ...
