Microperimetric evaluation of macula in retinopathy of membranoproliferative glomerulonephritis type II: a case report.
OBJECTIVE
To report on the microperimetric evaluation of the central visual field in a patient with retinopathy due to membranoproliferative glomerulonephritis.


METHODS
The central 20 degrees 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 corresponding window defects on fundus fluorescein angiogram.


RESULTS
Static threshold perimetry of the central 20 degrees 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.
