영문 초록

Purpose: To investigate the clinical effect and complications of patterned scanning laser photocoagulation with short exposure time in diabetic retinopathy. Methods: A prospective study was performed on patients with diabetic retinopathy who required panretinal photocoagulation (PRP). Twenty-nine eyes of twenty five consecutive patients underwent patterned scanning laser photocoagulation with exposure time of 0.02 sec over the entire retina. Pain score at treatment, best-corrected visual acuity, the development of macular edema, regression of neovascularization in fluorescein angiography, and related complications were monitored during a three-month follow-up. Results: Treatment time for PRP was much reduced to 6.1 min on the entire retina. Pain during the photocoagulation was moderate, and enabled patients to finish PRP with ease. During a three-month follow-up, visual acuity was well preserved. Foveal minimum thickness increased at 1 month after treatment and maintained in a study period of three months. Macular volume showed significant increase (3.6%) at 1 month after treatment, maximum increase (9.8%) at 2 months, and persistent increase (4.9%) at 3 months. In every patient with very severe nonproliferative diabetic retinopathy, retina was maintained, and in 10 of 18 eyes with proliferative diabetic retinopathy, neovascularization regressed during follow-up period. No significant complication occurred except a transient vitreous hemorrhage in one eye. Conclusions: Patterned scanning laser photocoagulation with short exposure time may induce transient macular edema, but the visual acuity was preserved without any other significant complication. It is considered to be a safe and efficient treatment method in diabetic retinopathy.
