This study examines the influence of diabetic and laser photocoagulation on the reflection spectra of the macula. In the investigation 43 patients with type II diabetes mellitus and 33 normals were included. It was shown that the optical density in diabetics is increased compared to normals. After laser photocoagulation the reflection spectra have changed, suggesting a decrease in optical density. It is proposed that the therapeutic effect of photocoagulation in diabetic retinopathy is related to an alteration in blood flow in the choroid.
