Late-onset retinal oxalosis in primary hyperoxaluria type 2.

Purpose: To report a previously undescribed case of late-onset vision loss due to retinal oxalosis in a patient with primary hyperoxaluria type 2 (PH2).

Observations: An 82-year-old female with a history of biopsy-proven oxalate nephropathy developed vision loss 8 months after end stage kidney disease. She developed progressive retinal ischemia secondary to crystal deposition.
