Comment on: Optical coherence tomography angiography in acute unilateral nonarteritic anterior ischemic optic neuropathy: A comparison with the fellow eye and with eyes with papilledema

Abstract

Sir, I was interested to read the article by Gandhi et al.,[1] who reported the presence of peripapillary choroidal filling defect in acute nonarteritic anterior ischemic optic neuropathy (NA‐AION) seen on optical coherence tomography angiography. In 1974, I described, for the first time, the clinical entity of “anterior ischemic optic neuropathy.”[2] Since then, I have exhaustively investigated, both experimentally and clinically, the pathogenesis and various aspect of NA‐AION, including doing fluorescein fundus angiographic (FFA) studies in over a thousand patients with acute NA‐AION. I have described my findings extensively in numerous of publications for more than 40 years and recently summarized those in my book entitled “Ischemic Optic Neuropathies.”[3] In the light of those studies, I have the following comments about the article by Gandhi et al.[1]
