purpose: to measure macular thickness in normal subjects with respect to age and gender using cirrus hd-oct in rasht city. methods: in this cross-sectional study, 112 normal subjects were randomly selected. both eyes of each subject were included and all subjects underwent complete eye examinations. macular thickness map protocol with macular cube 512×128 was selected, and the average thickness...

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 compare the ability of scanning laser polarimetry (gdx vcc), and optical coherence tomography (oct) to discriminate eyes with primary open angle glaucoma (poag) from normal eyes and to assess the relationship between their parameters methods : eighty-seven glaucomatous eyes of 87 patients and 25 normal eyes were enrolled. the mean age of patients and normal group were 54.96±18.34 a...

Background: Multiple Sclerosis (MS) is a neurodegenerative disease of central nervous system. Different approaches have been developed to study MS progression and cognitive dysfunction as the major symptom of the disease. The current study compared Optical Coherence Tomography (OCT) and Corpus Callosum Index (CCI) for the early evaluation of cognitive dysfunction in MS patients.  Objectives: T...

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...
