CLINICAL SCIENCES Differentiating Optic Disc Edema From Optic Nerve Head Drusen on Optical Coherence Tomography
Methods: Optical coherence tomographic images from 60 subjects (20 with ODE, 20 with ONHD, and 20 control subjects) were assessed qualitatively and quantitatively. Qualitative criteria for ODE included an elevated optic nerve head with smooth internal contour and subretinal hyporeflective space (SHYPS) with recumbent “lazy V” pattern. Optic nerve head drusen displayed a “lumpybumpy” internal op...
متن کاملDifferentiating optic disc edema from optic nerve head drusen on optical coherence tomography.
OBJECTIVE To assess optical coherence tomography in differentiating optic disc edema (ODE) due to papilledema and other optic neuropathies from optic nerve head drusen (ONHD). METHODS Optical coherence tomographic images from 60 subjects (20 with ODE, 20 with ONHD, and 20 control subjects) were assessed qualitatively and quantitatively. Qualitative criteria for ODE included an elevated optic ...
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 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 ...
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 ...
