In an earlier paper (Karpe and Rendahl, 1952), an account was given of 100 cases of detachment of the retina, in which the course of the disease was studied with the electroretinogram (ERG). Since then, an additional 150 cases have been followed with the ERG at the same eye clinic. It has therefore been considered expedient to analyze these total 250 cases in order to complement the earlier investigation, to confirm its results, and to attempt further elucidation of a number of essential problems regarding the nature of retinal detachment.
In the aforementioned paper, it was first of all shown that, as could be expected, retinal detachment is associated with a marked deterioration in the ERG and that this deterioration runs to some extent parallel to the size of the detached area. The investigation nevertheless showed that some additional factor must exist which determines the size of the b-potential on
