Phenylephrine Affects Peripapillary Retinal Vasculature—an Optic Coherence Tomography Angiography Study
Purpose: To evaluate and compare the effect of topical mydriatic eye drops (0.5% tropicamide alone, and a 0.5% tropicamide/0.5% phenylephrine mixture) on the retinal perfusion using optic coherence tomography angiography (OCTA). Methods: The perfused vessel density in the macular and peripapillary areas of both eyes was measured in eight healthy subjects using OCTA and a split-spectrum amplitud...
متن کاملOptical coherence tomography angiography of the peripapillary retina and optic nerve head in dominant optic atrophy.
Peripapillar and nerve head vessel density (VD) was measured in 10 patients affected by Dominant optic atrophy (DOA) using optical coherence tomography angiography (OCT-A) and compared to the measurements of 15 age- and gender-matched controls. DOA patients showed VD reduction, mostly in the temporal and inferotemporal peripapillary sectors, according to the preferential involvement of the papi...
متن کاملOptical coherence tomography angiography changes in radial peripapillary capillaries in Leber hereditary optic neuropathy
Purpose To present a report of longitudinal changes in radial peripapillary capillaries (RPC) and changes in retinal full thickness (RFT) and peripapillary retinal nerve fiber layer (RNFL) in a patient with Leber hereditary optic neuropathy (LHON). Observations A 42-year-old man presented with acute- and presymptomatic-stage LHON in the left (OS) and right (OD) eyes, respectively, at the init...
متن کاملOptical Coherence Tomography Angiography of the Peripapillary Retina in Glaucoma.
IMPORTANCE Vascular factors may have important roles in the pathophysiology of glaucoma. A practical method for the clinical evaluation of ocular perfusion is needed to improve glaucoma management. OBJECTIVE To detect peripapillary retinal perfusion in glaucomatous eyes compared with normal eyes using optical coherence tomography (OCT) angiography. DESIGN, SETTING, AND PARTICIPANTS Prospect...
متن کاملOptical Coherence Tomography Angiography of Peripapillary Retinal Blood Flow Response to Hyperoxia.
PURPOSE To measure the change in peripapillary retinal blood flow in response to hyperoxia by using optical coherence tomography (OCT) angiography. METHODS One eye of each healthy human participants (six) was scanned with a commercial high-speed (70 kHz) spectral OCT. Scans were captured twice after 10-minute exposures to normal breathing (baseline) and hyperoxia. Blood flow was detected by t...
