OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FINDINGS IN ACUTE RETINAL NECROSIS.
Retinal Cases & Brief Reports 2018 July 26
PURPOSE: To report clinical features of acute retinal necrosis (ARN) using optical coherence tomography angiography.
METHODS: A 59-year-old female patient presented with blurred vision in the left eye for 1 day. The patient presented posterior uveitis with multiple peripheral areas of retinal pallor with presumed acute retinal necrosis. Herpes simplex virus Type 1 infection was confirmed after serologic tests, and the polymerase chain reaction analysis of the aqueous humor tested positive.
RESULTS: The left eye examination revealed anterior chamber reaction, mild vitritis, optic disk swelling, and yellowish white retinal lesions with discrete borders along the superotemporal arcade and temporal periphery. Baseline optical coherence tomography angiography revealed decreased vascular density of superficial and deep plexuses of superotemporal macular region. One month after oral valacyclovir 2,000 mg twice daily, visual acuity and retinal lesions improved, and optical coherence tomography angiography images showed improvement of vascular density.
CONCLUSION: Occlusive arterial vasculopathy is one of the main clinical characteristics of acute retinal necrosis. We herein describe for the first time the features of retinal vasculature in acute retinal necrosis revealed by optical coherence tomography angiography, showing decreased vascular density of superficial and deep plexuses.
