The authors studied the ERG of 51 cases of bilateral high degree myopia with unilateral retinal detachment and 50 cases of normal eyes. It was found that ERG in the former were characterized by a marked drop in the amplitude of the a-wave, particularly in the eye of retinal detachment, for which the ERG further diminished or failed to appear depending on the duration and extent of the lesion. Since a-waves originate from the sensory visual cells, the result was consistent with the pathology of high degree myopia and retinal detachment. The authors hold that periodic ERG examinations for dynamic surveillance is useful in monitoring the development of retinal detachment in high degree myopia.
作者对51例双侧高度近视伴单侧视网膜脱离患者及50例正常眼进行了视网膜电图（ERG）研究。发现前者的ERG表现为a波振幅明显下降，尤其是在视网膜脱离的眼，根据病变的持续时间和范围，该眼的ERG进一步降低或未出现。由于a波起源于视觉感觉细胞，这一结果与高度近视和视网膜脱离的病理情况相符。作者认为，定期进行ERG检查以进行动态监测，对于监测高度近视患者视网膜脱离的发展是有用的。
