• Ocular involvement from primary hyperoxaluria developed in one infant and one teenaged patient. Autopsy procedures in the first case used special histopathologic staining techniques to demonstrate a wider deposition of calcium oxalate crystals within the eye than was previously suspected. Clinical photographs and fluorescein angiograms in the older patient demonstrated a widespread retinal distribution of crystals with a periarterial predilection. This patient also demonstrated a unique acquired black macular lesion.
