Course: A Middle-aged Man With Macular Lesions and Vitritis

CME Credits: 1.00

Released: 2022-05-12

A 55-year-old US-born man with a history of cataract surgery in both eyes 3 years ago presented with worsening blurriness, photopsia, floaters, and intermittent eye redness for the past year, worse in the left eye. He was otherwise well. The referring physician was treating him with prednisolone eye drops for cystoid macular edema after recent left Nd:YAG capsulotomy. His best-corrected visual acuity was 20/20 OD and 20/30 OS with intraocular pressures of 20 mm Hg OD and 26 mm Hg OS. The anterior segments showed well-positioned posterior chamber intraocular lens implants with open posterior capsules. Dilated fundus examination revealed a small peripheral hypoautofluorescent chorioretinal scar in the right eye. In the left eye, there was trace vitreous haze and 2+ anterior vitreous cell. Multifocal chorioretinal scars extended from the left optic nerve into the macula in each quadrant (). These lesions showed variable hypoautofluorescence and hyperautofluorescence. On indocyanine green angiography (ICGA), the confluent hypoautofluorescent lesions showed loss of the choriocapillaris and prominent large choroidal vessels, whereas the mottled hypoautofluorescence and hyperautofluorescent lesions appeared to block the underlying fluorescence. Routine laboratory testing was unremarkable except for a positive interferon-gamma release assay for Mycobacterium tuberculosis. A chest radiograph was normal.
