• A female infant had progressive atypical pigmentary retinopathy with type 1 hereditary oxalosis. At the age of 3 months she had a flecked retina type of retinopathy and six months later she exhibited a unique type of atypical pigmentary retinopathy. This latter abnormality was characterized by a dense parafoveal hyperpigmented ring five disc diameters in size, and composed of a confluence of small rings of hyperpigmented retinal pigment epithelium surrounding whitish highly refractile calcium oxalate crystalline deposits.
