Microperimetric evaluation of macula in retinopathy of membranoproliferative glomerulonephritis type II: A case report

PURPOSE. To report on the microperimetric evaluation of the central visual field in a patient with retinopathy due to membranoproliferative glomerulonephritis. METHODS. The central 20 visual field was evaluated using fundus-related perimetry with (Nidek MP1) microperimeter in a patient with proven membranoproliferative glomerulonephritis type II, who had multiple drusen-like lesions involving the posterior pole of both eyes, with cor responding window defects on fundus fluorescein angiogram. RESULTS. Static threshold perimetry of the central 20 using a 10 dB threshold, Goldmann size II stimulus, with (Nidek-MP1) microperimeter showed reduction in retinal sensitivity in the parafoveal and in the temporal paramacular areas in both the eyes that had drusen-like lesions. CONCLUSIONS. Early loss of function in retinopathy of membranoproliferative glomerulonephritis type II can probably be detected by fundus-related microperimetry. (Eur J Ophthalmol 2006; 16: 634-6)
