  • Abstract
  • Look Inside

We compared the effects of focal photocoagula-tion with panretinal photocoagulation (PRP) in 108 eyes, 58 patients, with diabetic retinopathy of vary-ing severities. The eyes were classified into 6 groups by grading the extent of capillary nonper-fusion into 3 subgroups and the intensity ofextravasation of dye into 2 when seen by fluores-cein angiography.

Focal photocoagulation resulted in lesser rate of progression of retinopathy in eyes with localized capillary nonperfusion involving less than 3 guan-drants of the fundus and in those with mild extravasation. Retinopathy progressed at a higher incidence in eyes with extensive capillary nonper-fusion and profuse extravasation.
