Effects of different regimens of argon laser panretinal
photocoagulation (PRP) on contrast sensitivity were studied in 36
patients (36 eyes) having proliferative diabetic retinopathy (PDR) with
no clinically significant macular oedema.
All eyes were randomly assigned to be treated with argon green PRP
either in single session (group A), two sessions separated by one week
interval (group B) or three sessions each separated by one week interval
(group C). In each eye contrast sensitivity was evaluated using
Cambridge Low-Contrast Sensitivity Charts before laser treatment then
one week and 3 months after end of treatment. |
