This monograph contains a classification of diabetic retinopathy and numerous colored illustrations describing the various changes produced by this disease. The color reproductions are of good quality and should enable the ophthalmologist to grade a patient's fundus according to the author's classification, which is somewhat modified from the Airlie classification.
The author is a great believer in the beneficial effect of photocoagulation in the treatment of this disease. He cites a number of his own patients in whom photocoagulation of various stages of diabetic retinopathy was apparently beneficial. Since he does not have any controls or any randomized studies, this evidence is anecdotal at best. The cookbook approach to photocoagulation in diabetic retinopathy is an unwarranted oversimplification not substantiated by any evidence that the author can present.
While the author's classification is logical, reasonable, and well illustrated, his uncritical approach to the treatment is a step in the wrong direction.
