Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases.  Furtherm...

Convolutional neural networks are powerful tools for image segmentation and classification. Here, we use this method to identify and mark the heart region of Drosophila at different developmental stages in the cross-sectional images acquired by a custom optical coherence microscopy (OCM) system. With our well-trained convolutional neural network model, the heart regions through multiple heartbe...

purpose : to describe the macular thickness map of iranian adult with normal retinal status as measured by cirrus’ optical coherence tomography (oct) instrument methods : in this cross-sectional study, one eye of subjects with normal ocular examination and retinal status of at least one eye were recruited. the 512×128-scan pattern and scan area of 6×6 mm2 with software version 4 protocol in cir...

purpose : to evaluate the effectiveness of intravitreal triamcinolone acetonide on visual acuity and macular thickness using optical coherence tomography in macular edema associated with nonischemic central retinal vein occlusion (crvo). design : a prospective interventional case series. patients & methods : twenty eyes of 25 patients with nonischemic crvo and macular edema with visual acuity o...

Our aim was to study optical coherence tomographic findings in a case of Toxocara granuloma. A patient with a cicatricial macular lesion, diagnosed as ocular toxocariasis, was examined with optical coherence tomography. In optical coherence tomography images, the macular granuloma appeared as a highly reflective round mass protruding above the retinal pigment epithelium with two other surroundi...

Optical coherence tomography is a powerful tool that can e ectively provide detail information of biological tissue structure. The axis resolution of optical coherence tomographyhas achieved sub-micrometer andweare interested in its ultrahigh resolution that can be practically utilized for clinical application. In this article, the basic system calibration is discussed; we systematically demons...
