Computer-enhanced studies of diabetic retinopathy: II

Data from 5,818 eyes with diabetic retinopathy were entered into a computer. Retrieval was either panoramic, encompassing the whole bank, or directed to small groups for in-depth investigation. In this study, panoramic retrieval pertains to the relative frequency of nonproliferative and proliferative diabetic retinopathy, to insulin dependence, and to the visual prognosis associated with these variables. Small-group studies examined traction detachment and vitreous hemorrhage in relation to visual prognosis and postmortem data related to age at death and "final vision".
