PURPOSE The pattern electroretinogram (PERG) is reduced in early glaucoma and in some eyes with ocular hypertension (OHT). This study was designed to test the ability of the PERG to predict the development of visual field loss in OHT eyes. METHODS In 29 eyes of 18 patients with high-risk OHT, the visual fields were tested, and the PERG was recorded using counterphasing checkerboard patterns at check sizes of 0.8 degrees and 15 degrees at 16 reversals/sec. The visual fields were retested 11-31… CONTINUE READING
