[ERG study of high degree myopia with retinal detachment].
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.
