Optical 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 ...
متن کاملOptical Coherence Tomography Angiography of the Optic Disc; an Overview
Different diseases of the optic disc may be caused by or lead to abnormal vasculature at the optic nerve head. Optical coherence tomography angiography (OCTA) is a novel technology that provides high resolution mapping of the retinal and optic disc vessels. Recent studies have shown the ability of OCTA to visualize vascular abnormalities in different optic neuropathies. In addition, quantified ...
متن کاملOptical coherence tomography angiography of optic disc perfusion in non-arteritic anterior ischemic optic neuropathy.
AIM To compare the optic disc blood flow of non-arteritic ischemic optic neuropathy (NAION) eyes with normal eyes. METHODS The optic disc blood flow densities of diagnosed non-acute phase NAION eyes (21 eyes, 14 individuals) and normal eyes (19 eyes, 12 individuals) were detected via Optovue optical coherence tomography angiography (OCTA). The optic disc blood flow was measured via Image J so...
متن کاملOptical 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 کاملOptic Disc Vascularization in Glaucoma: Value of Spectral-Domain Optical Coherence Tomography Angiography
Purpose. To detect changes in optic nerve head (ONH) vascularization in glaucoma patients using spectral-domain OCT angiography (OCT-A). Material and Method. Fifty glaucoma patients and 30 normal subjects were evaluated with OCT-A (AngioVue®, Optovue). The total ONH vessel density and temporal disc vessel density were measured. Clinical data, visual field (VF) parameters, and spectral-domain OC...
