In retinal detachment the amplitude of the b-wave of the electroretinogram (ERG) has been observed to be characteristically reduced. It has also been found that a reduction in amplitude of the ERG is usually also present in the opposite eye of the patient with the detachment. This has been reported, by investigators all over the world, during the past 10 years.1-9

Recently, Rendahl10 has published a follow-up article on his original series, bringing the total he has studied to 250 cases. The conclusions drawn in this paper are that there is a statistically significant difference in the amplitude of the ERG between those patients who had a "successful" operative result and those who did not. Because of the great variation in individual cases, however, it was felt to be difficult to assess prognostic value to the ERG in a particular case. The author also felt, however, that in
