Purpose: To investigate the effect of focal and grid pattern PASCAL photocoagulation treatment in diabetic macular edema patients.
Methods: A total of 72 patients (75 eyes) who were diagnosed as diabetic macular edema were retrospectively analyzed. The patients were divided into 3 groups as follows: group 1 (31 patients, 31 eyes) received an intravitreal bevacizumab injection, group 2 (17 patients, 20 eyes) underwent focal and grid pattern PASCAL photocoagulation treatment, and group 3 (24 patients, 24 eyes) underwent focal and grid pattern argon photocoagulation treatment. Macular thickness and visual acuity (logMAR) of 75 eyes were compared among groups before and after treatments.
Results: Visual acuity improved in 13 eyes (65.0%) in group 1, 16 eyes (51.6%) in group 2, and in 10 eyes (41.6%) in group 3; however, there was no statistical significance. Macular thickness reduction occurred in 24 eyes (77.4%) in group 1 and 13 eyes (65.0%) in group 2 which were statistically significant decreases at only 1 month after treatment (p < 0.05).
Conclusions: Focal and grid pattern PASCAL photocoagulation is a good therapeutic option for diabetic macular edema. Focal and grid pattern PASCAL photocoagulation is as effective as intravitreal bevacizumab injection or focal and grid pattern argon photocoagulation treatment.
