Arch Ophthal84:158-165,1970).Six years ago, I applied light coagulation in apparently healthy retina to limit the anticipated spread of inferior retinoschisis in two brothers. No harmful effects have been noted, nor has there been any progression of the condition.1However, subsequent personal experience of 54 cases confirms the observation2,3 that maculopathy is invariable and is the main cause of the visual defect. In addition, except for occasional vitreous hemorrhage or exudation between the leaves of split retina usually during adolescence, it has been shown4,5 that the condition is largely stationary throughout life. This observation also seems valid. A priori, therefore, light coagulation could seldom be of value in these cases. Dr. Brockhurst has now shown that it has considerable
