　さき^1）に網膜剥離復位後のERPについて報告し，術前に比べ多くの症例で有意の振幅増大がみられることより，人間においても剥離後損傷された視細胞外節が再生修復される可能性があるむねを指摘した。

　今回さらにERG検査所見とあわせ，その修復状態について検討を加えたので，ここに報告する。

I examined 61 eyes with idiopathic retinal detachment before and 2 months after successful surgery by means of electrorctillography with particular attention to the early receptor potential(ERP). The ages of the patients ranged from 15 to 75 years. The detachment, involved more than three-fourths of the whole retinal area and had persisted less than one month after the apparent onset.

The results obtained were as follows:

1) The mean ERP amplitude after the opera-tion (75.4±25.1μV) was statistically, greatly increased (p <0.001), as compared with the mean value prior to surgery (55.1±24.4 μV).
