Superficial and Deep Foveal Capillary Plexus Hypoperfusion on Optical Coherence Tomography Angiography in Unilateral Epiretinal Membrane

CRO (Clinical & Refractive Optometry) Journal, 2020
Purpose: To document and evaluate the presence of hypoperfusion of the foveal superficial and deep capillary plexus in a patient with unilateral epiretinal membrane (ERM) as seen on optical coherence tomography angiography (OCTA). Methods. A 73-year-old male presented for a comprehensive exam with a history of an ERM OD.

Retinal Vascular Degeneration in the Transgenic P23H Rat Model of Retinitis Pigmentosa

Frontiers in Neuroanatomy, 2018
Retinitis pigmentosa (RP) is a group of inherited retinal degenerative diseases involving a progressive degeneration of photoreceptor cells. Following the loss of photoreceptors, retinal vascularization tends to decrease, which seems to play a role in ...
