Optical coherence tomography of pneumatic displacement of optic disc pit maculopathy.
BACKGROUND The authors have previously concluded that fluid from an optic disc pit creates an inner layer separation (ILS) of the retina. An outer layer detachment (OLD) centred on the macula is a secondary phenomenon that causes a dense central scotoma. Pneumatic displacement of the OLD effects an improvement in central vision. Pathology to confirm these conclusions is lacking. Intraretinal im...
متن کاملOptical coherence tomography angiography in pediatric choroidal neovascularization
PURPOSE To report two cases of pediatric choroidal neovascularization (CNV) and the associated neo-vascular and retinal findings identified on Optical Coherence Tomography Angiography (OCTA) imaging. METHODS A 14-year-old boy with handheld laser-induced maculopathy-related CNV and a 13-year-old boy with idiopathic CNV were evaluated with visual acuity testing, slit-lamp exam, fundus photograp...
متن کاملOptical coherence tomography angiography of non-exudative choroidal neovascularization
Yan Ke Xue Bao 2016;31(4):243-245 ykxb.amegroups.com Age-related macular degeneration (AMD) has been classified in two groups, neovascular and non-neovascular, which historically has been synonymous with exudative and non-exudative, respectively. Neovascular AMD occurs when pathologic blood vessels, choroidal neovascularization (CNV), arise from the choroid and extend above Bruch’s membrane tow...
متن کاملAutomated choroidal neovascularization detection algorithm for optical coherence tomography angiography.
Optical coherence tomography angiography has recently been used to visualize choroidal neovascularization (CNV) in participants with age-related macular degeneration. Identification and quantification of CNV area is important clinically for disease assessment. An automated algorithm for CNV area detection is presented in this article. It relies on denoising and a saliency detection model to ove...
متن کاملOptical coherence tomography angiography of optic disc perfusion in glaucoma.
PURPOSE To compare optic disc perfusion between normal subjects and subjects with glaucoma using optical coherence tomography (OCT) angiography and to detect optic disc perfusion changes in glaucoma. DESIGN Observational, cross-sectional study. PARTICIPANTS Twenty-four normal subjects and 11 patients with glaucoma were included. METHODS One eye of each subject was scanned by a high-speed ...
