網膜剥離におけるERGの意義

ERG in detachment of the retina

緒言

　網膜剥離のERGについてはKarpe,Rendahlをはじめ数人の臨床的ERG研究者の発表があり，我教室からも1957年既に一度報告したが其後ERG描記方法に多少改良を加え症例も或程度の数を得たので此処に再び本症におけるERGの意義について主として統計的な立場から検討を加えて見たい。

An electroretinographical study was performed on 98 cases with retinal detachment, 77 of whom were idiopathic.

As light stimulus the authors used a series of stroboscopic light flashes, and measured the a+b potential to the lowest stimulus intensity (I 12, 5 arbitrary unit) and a, potential to the highest stimulus intensity (I 100) in the scotopic condition.

The data was statistically evaluated.

The results obtained are as follows.
