purpose: comparing the optical coherence tomography (oct) pachymetry patterns in keratoconus suspect and normal people methods: thirty-two keratoconus suspects and 36 healthy eyes were selected within the age range of 20-30 yrs. their pachymetry pattern was obtained through oct visante in the minimum thickness spot, upper and lower corneal difference (i-s), lower temporal, and upper nasal thick...

purpose: to evaluate the rate of optical coherence tomography (oct) grid decentration in a routine practice and its effect on thickness measurements methods: topcon spectral domain oct scans from various macular diseases including age related macular degeneration, diabetic macular edema, macular pucker and central serous chorioretinopathy (cscr) were studied in all patients visited during seven...

introduction:visualization of inner ear structures is a valuable strategy for researchers and clinicians working on hearing pathologies. optical coherence tomography (oct) is a high-resolution imaging technology which may be used for the visualization of tissues. in this experimental study we aimed to evaluate inner ear anatomy in well-prepared human labyrinthine bones.materials and methods:thr...

purpose : to study optical coherence tomography (oct) findings in high myopic patients with the history of uncomplicated cataract surgery methods : the sample included 34 eyes of 24 highly myopic patients with an axial length (al) of 26 mm or more and a spherical equivalent (se) of 8.0 diopter (d) or more who had uncomplicated phacoemulsification cataract surgery. octs were done in multiple sec...

diagnosis of corneal diseases is possible by measuring and evaluation of corneal thickness in different layers. thus, the need for precise segmentation of corneal layer boundaries is inevitable. obviously, manual segmentation is time‑consuming and imprecise. in this paper, the gaussian mixture model (gmm) is used for automatic segmentation of three clinically important corneal boundaries on opt...

purpose : to report the evaluation of the treatment response in choroidal hemangioma with application of enhanced depth imaging optical coherence tomography (edi-oct) technique case report : a 73-year-old woman with a circumscribed choroidal hemangioma in the posterior pole of her left eye underwent photodynamic therapy and intravitreal injection of bevacizumab. edi-oct obtained from the affect...

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 : evaluating the effects of memantine on visual function after scleral buckling for rhegmatogenous retinal detachment (rrd) methods : in a double blind prospective randomized clinical trial, 61 patients with clinical diagnosis of less than 4 weeks macula-off rrd who had successful scleral buckle surgery had been selected and divided into two randomized groups. thirty of them received 5 ...

background: headache is one of the most disturbing symptoms with common neurological signs. variations in optic nerve perfusion quality or retinal microcirculation may end up in ganglion cell damage in patients with migraine. methods: sixty patients diagnosed with migraine and thirty normal individuals were evaluated in groups including migraine with aura, migraine without aura and controls. re...

purpose : to evaluate usefulness of anterior segment optical coherence tomography (as-oct) in evaluation of filtering bleb functionality and to correlate its findings with clinical bleb examination methods : in this cross-sectional, descriptive study 55 eyes with apparently functional bleb were evaluated. following a comprehensive ophthalmic examination, filtering bleb grading was performed bas...
