A 41-year-old man presented with bilateral central “donut-shaped” scotomas and bluish/purplish
hue 5 days after consuming 3 to 4 times higher than recommended dose of sildenafil.
Vision was 20/20 with mild dyschromatopsia and normal pupils, intraocular pressure,
and motility. Trace macular mottling was noted (Fig 1A and C). Near-infrared imaging showed abnormal circumferential hyporeflectance (Fig 1B and D; red arrows). On OCT, there was bilateral paracentral ellipsoid layer mottling, loss of interdigitation
zone band, and normal choroidal thickness (Fig 1E and F; yellow arrows). A diagnosis of acute macular neuroretinopathy variant was made. The patient resumed
normal sildenafil dosing, resulting in complete resolution of symptoms and OCT abnormalities
over the next 7 months (Fig 1G and H). (Magnified version available at www.ophthalmologyretina.org).
