purpose : to evaluate the retinal nerve fiber layer (rnfl) and central corneal thickness (cct) in patients with exfoliation syndrome (xfs) methods : in this comparative case series we measures rnfl thickness and cct 30 patients with xfs and 30 age and sex matched healthy subjects who met the inclusion criteria. results : average rnfl in xfs group were significantly thinner than controls (94.36±...

PURPOSE To investigate the vascular microcirculation changes in the retinal nerve fiber layer (RNFL) in normal, glaucoma suspect, and open-angle glaucoma (OAG) groups using optical coherence tomography-based microangiography (OMAG). METHODS One eye from each subject was scanned with a Cirrus HD-OCT 5000-based OMAG prototype system montage scanning protocol centered at the optic nerve head (ON...

PURPOSE To report retinal nerve fiber layer (RNFL) defect identification and quantification in RNFL thickness maps according to the structural RNFL loss, and to evaluate diffuse RNFL defects. METHODS A total of 170 patients with glaucoma and 186 normal subjects were consecutively enrolled. We defined RNFL defects in an RNFL thickness map by the degree of RNFL loss. The reference level for RNF...

ABSTRACT Purpose: to compare the Subfoveal choroidal thickness (SFCT) and Retinal Nerve Fiber Layer Thickness (RNFL) of amblyopic normal fellow eyes. Design: Prospective, cross-sectional, observational case series. Methods: Forty patients age 12 41 years (mean 23.73 ± 6.42) with unilateral amblyopia were studied. Among them, 11(28.2%) had secondary strabismus 29(71.8 %) anisometropic amblyopia....

Retinal nerve fiber layer (RNFL) photographs from 26 patients with Alzheimer's disease and 23 normal, age-matched, control subjects were reviewed for quality and abnormalities by two observers. A higher proportion of Alzheimer's patients showed RNFL abnormalities when compared to control subjects. There was some disagreement between the two observers regarding quality and frequency of abnormali...

purpose: to examine the relationship between retinal nerve fiber layer (rnfl) measurements obtained using scanning laser polarimetry with variable corneal compensation (vcc) and central corneal thickness (cct) measurements using pentacam in myopic patients methods: the study included 45 eyes from 45 myopic patients with intraocular pressure (iop) measurements≤21 mmhg. all participants had norma...

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. ...

normal 0 false false false en-us x-none ar-sa background: this study was designed to investigate the effect of vitiligo on the retinal nerve fiber layer (rnfl) thickness. materials and methods: this prospective study was conducted in the department of ophthalmology at kä±rä±kkale university during 2010 and 2011.sixty eight eyes of 34 vitiligo patients were included in the study. eighty four eye...

PURPOSE The retinal nerve fiber layer (RNFL) exhibits birefringence that is due to the oriented cylindrical structure of the ganglion cell axons. Possible birefringent structures include axonal membranes, microtubules (MTs), and neurofilaments. MTs are generally assumed to be a major contributor, but this has not been demonstrated. In this study, the MT depolymerizing agent colchicine was used ...

PURPOSE To investigate the influence of intersubject variation in ocular parameters on the mapping of retinal locations to the retinal nerve fiber layer and optic nerve head. METHODS One hundred retinal nerve fiber layer (RNFL) bundle photographs from 100 subjects were optimized digitally and single RNFL bundles manually traced back to the ONH where their entry point was noted. A 24-2 visual ...
