In this report, 31 cases of Coats disease are reviewed. The location of vascular abnormality and exudation was found to be distinctly more common in the temporal retina (especially superiorly) and in the macular and perimacular areas. Xenon arc photocoagulation or cryotherapy or both as well as a scleral buckling procedure in cases of retinal detachment appeared to be helpful modes of therapy, especially if two or less quadrants were involved. The possibility of recurrence of the disease was emphasized by the fact that three patients developed new lesions several years after completion of treatment.
