Multifocal Visual Evoked Potentials and Multifocal Electroretinograms in Papillorenal Syndrome

Arch Ophthalmol. 2002;120(6):870-871. doi:10.1001/archopht.120.6.870

A 17-YEAR-OLD patient who had received a renal transplant was evaluated for possible glaucoma. Visual acuity was 20/20 at distance with 6/6 AO/HRR color plates correctly identified in each eye. The Humphrey 24-2 visual fields displayed binasal field loss (Figure 1). There was no relative afferent pupillary defect. The intraocular pressure was 15 mm Hg OU. The results of a slitlamp examination were normal. The ocular fundus examination revealed excavated-appearing discs and an absence of the normal central retinal vascular system, with all vessels entering and exiting from the disc margin (Figure 2). No signs of retinal disease were observed. Multifocal electroretinography records for both eyes were within normal limits (Figure 3). Multifocal visual evoked potential1 responses, which were grouped in quadrants, were absent nasally in both eyes.2 The location of the diminished responses corresponded with the binasal visual field defects (Figure 4).
