A 60-year-old Vietnamese man presented with a 2-week history of progressive bilateral vision loss associated with bilateral hearing loss. He had a history of well controlled diabetes and ischemic heart disease. There was no other relevant ocular history, and he was otherwise in good health. Best-corrected visual acuity was 20/60 in both eyes. Slit-lamp examination showed bilateral anterior uveitis, vitritis, disc swelling with nerve fiber layer hemorrhages (Figures 1 and 2), and multifocal subretinal exudative detachments (Figure 3).
