The Effect of Optic Disc Center Displacement on Retinal Nerve Fiber Layer Measurement Determined by Spectral Domain Optical Coherence Tomography
PURPOSE To investigate the effect of optic disc center displacement on retinal nerve fiber layer (RNFL) measurement determined by spectral domain optical coherence tomography (SD-OCT). METHODS The optic disc center was manipulated at 1-pixel intervals in horizontal, vertical, and diagonal directions. According to the manipulated optic disc center location, the RNFL thickness data were resampl...
متن کاملcomparison of peripapillary retinal nerve fiber layer thickness measured by two different optical coherence tomography devices
purpose: to determine agreement between peripapillary retinal nerve fiber layer (rnfl) thickness measurements by two different spectral domain optical coherence tomography (sd-oct) machines. methods: both eyes of 89 subjects were evaluated using cirrus oct (carl zeiss meditec, inc. dublin, ca, usa) and topcon oct (3d oct 1000, topcon corporation, tokyo, japan). one eye was randomly selected in ...
متن کاملChanges in retinal nerve fiber layer and optic disc algorithms by optical coherence tomography in glaucomatous Arab subjects
PURPOSE To assess the difference in retinal nerve fiber layer (RNFL) and optic disc algorithms between glaucomatous and normal Arab subjects using optical coherence tomography (OCT). METHODS RNFL thickness and optic disc parameters were obtained in 65 patients aged 50.1 ± 7.7 years. Percentage differences in all parameters were calculated and analyzed between groups. RESULTS The mean RNFL t...
متن کاملEvaluation of Retinal Nerve Fiber Layer Thinning in Myopic Glaucoma: Impact of Optic Disc Morphology.
Purpose The purpose of this study was to investigate the role of optic disc torsion on the rate of progressive retinal nerve fiber layer (RNFL) thinning in patients with myopic open-angle glaucoma. Methods We included 102 patients with myopic open-angle glaucoma accompanied by glaucomatous damage confined to a single hemiretina who were followed up over a 5-year period. We divided the subject...
متن کاملfindings of optical coherence tomography of retinal nerve fiber layer in two common types of multiple sclerosis
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...
