M. Striga et M. Ivanisevic, COMPARISON BETWEEN EFFICACY OF FULL-SCATTER AND MILD-SCATTER (PANRETINAL) PHOTOCOAGULATION ON THE COURSE OF DIABETIC RUBEOSIS IRIDIS, Ophthalmologica, 207(3), 1993, pp. 144-147
The study enrolled 59 eyes with rubeosis iridis and proliferative diab
etic retinopathy. The efficacies of two types of panretinal photocoagu
lation ('full' and 'mild' scatter) on the course of diabetic rubeosis
iridis were compared. The mean posttreatment follow-up period was 22+/
-4.8 months. After application of full-scatter photocoagulation (1,200
-1,600 spots) in 27 eyes, rubeosis iridis regressed in 70.4% cases, re
mained unchanged in 14.8% and deteriorated in 14.8%. After mild-scatte
r photocoagulation (400-650 spots) in 32 treated eyes, rubeosis iridis
regressed in 37.5% cases, 34.4% was unchanged, while deterioration wa
s found in 28.1%. A better therapeutic effect of panretinal photocoagu
lation in regression of diabetic rubeosis iridis was obtained, if the
total dose of the applied laser spots was higher.
