The authors evaluated the usefulness of multifocal electroretinograms (m-ERGs) in assessing for glaucoma. They recorded m-ERGs in 23 eyes of 13 patients with open-angle glaucoma, ten eyes of five patients with low-tension glaucoma, two eyes of one patient with capsular glaucoma, and 25 eyes of 21 individuals with no glaucoma, who served as controls. The amplitudes of m-ERG responses were smaller in eyes with glaucoma than in controls and the latencies were significantly longer in eyes with glaucoma than in controls. They then compared the sum of the m-ERG amplitudes and latencies with the mean sensitivity (MS) and mean defect (MD) identified using the Octopus G-1 program and compared the m-ERG amplitudes in each area with the corrected loss variance (CLV). The sum of the m-ERG amplitudes and the latencies did not correlate with MS or MD. However, the amplitudes in an area that corresponded to the Bjerrum area did correlate with the CLV.LA: Japanese
