Swept-Source Optical Coherence Tomography and OCT Angiography of Minocycline-Induced Retinal and Systemic Hyperpigmentation

Abstract

This is a report of an 80-year-old man with a history of rosacea and rhinophyma treated for 15 years with oral minocycline who developed significant minocycline-induced hyperpigmentation. He also had a history of Fuchs' endothelial dystrophy and had undergone penetrating keratoplasty in the right eye. Best-corrected visual acuity was 20/60 in both eyes. Examination revealed slate-grey hyperpigmentation of his body, face, and sclera and black, confluent pigmentation in the central maculae of both eyes. Green wavelength fundus autofluorescence demonstrated speckled hyperautofluorescence in the right eye, and swept-source OCT and OCTA demonstrated pigmented epithelial detachments and significant signal blocking without choroidal neovascularization.
