Eye Research Institute, Boston, Mass.

The electrooculograms (EOGs) of 24 patients with central retinal vein obstruction (CRVO) were correlated with fundus appearance and with the electroretinogram (ERG) b/a wave ratio. Of the 24, 17 (70.8%) showed abnormal EOGs [light peak versus dark trough ratio (Lp/Dt) of less than 1.85]. The EOG Lp/Dt ratio was abnormal in 64.7%, although the ERG b/a ratio was within normal limits. Though the exact mechanism is still not entirely clear, the EOG became abnormal in most patients with CRVO and correlated well with the severity of the disease.
