OBJECTIVE: To report on a case of retinal pigment epithelium (RPE) toxicity apparently associated with ritonavir. METHODS: We describe a case of gradual-onset blurry vision in both eyes in a 30-year-old HIV-positive male on Highly-Active Antiretroviral Therapy (HAART) including ritonavir Results: The patient presented with a visual acuity of 3/10 in each eye, and fundoscopy revealed paracentral pigment mottling. Computerized perimetry showed a ring-scotoma in both eyes. Fluorescein angiography revealed an anular RPE defect in both eyes, congruent with hyperautofluorescent changes on autofluorescence imaging. Full-field ERG was normal. CONCLUSIONS: Since ritonavir has previously been linked with toxicity to the RPE, we consider this report as further evidence of this association.
