Pattern-reversal electroretinograms (ERGs) were recorded from seven patients, aged 50 to 69 years, with clinical diagnosis of unilateral ocular hypertension. In four of the seven patients the pattern ERG amplitude from the hypertensive eye was reduced below the normal level of variability, when compared with the amplitude from the opposite normotensive eye (ratio less than 0.8). In three of these four cases excavation of the optic disk in the hypertensive eye was observed 6 to 15 months after the recording of reduced pattern ERG. The finding suggests that pattern ERG may be an useful objective method for early detection of functional damage in eyes with increased intraocular pressure.
对7例年龄在50至69岁之间、临床诊断为单侧高眼压的患者进行了图形翻转视网膜电图（ERG）记录。与对侧血压正常眼的振幅相比，7例患者中有4例高血压眼的图形ERG振幅降低至正常变异性水平以下（比值小于0.8）。在这4例患者中的3例，在记录到图形ERG降低后6至15个月，观察到高血压眼视盘凹陷。这一发现表明，图形ERG可能是早期检测眼压升高患者眼部功能损害的一种有用的客观方法。
