We investigated the relationship between the peripapillary retinal nerve fiber layer and peripapillary retinal thickness in patients with diabetic macular edema. Fifty eyes (group I) with non-proliferative diabetic retinopathy and diabetic macular edema receiving intravitreal anti-VEGF injection, and 90 eyes (group II) without diabetic macular edema were included in this case-control study. The...

PURPOSE To compare the optical coherence tomography retinal nerve fiber layer and macular thickness measurements for detection of progressive axonal loss following acute traumatic optic neuropathy in a longitudinal study. METHODS Three patients with unilateral traumatic optic neuropathy were evaluated sequentially after trauma. Macular and retinal nerve fiber layer thickness measurements were...

OBJECTIVES Evaluation of the peripapillary retinal nerve fiber layer thickness, subfoveal choroidal thickness, and retinal vessel caliber measurements in children with thalassemia minor. METHODS In this cross-sectional and comparative study, 30 thalassemia minor patients and 36 controls were included. Heidelberg spectral domain optical coherence tomography was used for peripapillary retinal n...

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...

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...

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 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...

Glaucoma is characterized by a combination of structural changes in the retina and optic nerve head and functional perimetric damage. Examination and documentation of the retinal nerve fiber layer are essential for the diagnosis and monitoring of glaucoma. Spectral domain Optical coherence tomography (OCT) is a high resolution imaging device capable of obtaining reproducible retinal nerve fiber...

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...

PURPOSE To study the correlation between local perimetric field defects and glaucoma-induced thickness reduction of the nerve layer measured in the peripapillary area with scanning laser polarimetry (SLP) and spectral domain optical coherence tomography (SOCT) and to compare the results with those of a theoretical model. METHODS The thickness of the retinal nerve fiber layer was determined in...
