Summary

A 70-year-old woman was examined with a 10-day history of photopsia and floaters in her left eye. Her best-corrected visual acuity was 20/25 in both eyes, with a normal intraocular pressure and some nuclear sclerosis. Spectral-domain optical coherence tomography revealed a separated posterior vitreous, with a rolled internal limiting membrane flap and inner retinal dimples in the left eye. Optical coherence tomography angiography demonstrated reduced vessel density in both the superficial and deep capillary plexuses of the left fundus. Sixteen months earlier, she had received a single intravitreal Dexamethasone implant injection, due to inferotemporal branch retinal vein occlusion-related macular edema. A diagnosis of internal limiting membrane tear following an uneventful posterior vitreous detachment was reached and no treatment was recommended.
