Color fundus photograph of the right eye of a 55-year-old man with primary hyperoxaluria and oxalosis. Characteristic crystalline retinopathy (flecked retina), black geographic maculopathy, and partial optic atrophy are visible. In addition, occluded branches of central retinal artery due to calcium oxalate deposition are visible.
