[Ocular impairment during type II membranoproliferative glomerulonephritis].

Membranoproliferative glomerulonephritis type II (MPGN) is characterized by dense deposits within glomerular basal membrane and Bruch's membrane which result in retinal lesions similar to drusens. We observed a 50-year-old patient with chronic renal deficiency who developed central bilateral serous retinopathy with diffuse punctiforme yellow subretinal lesions. Ophthalmoscopic and angiographic aspects led to an MPGN type II diagnosis. Specific posterior segment lesions are described during MPGN type II. Dense deposits concerned both lamina densa of glomerular basal membrane and Bruch's membrane with choriocapillaris. The main ocular complications were central serous chorioretinopathy and choroidal neovascularization. We review the clinical and evolutive aspects of this disease.
