  • Preliminary clinical observation of short-pulse pattern scan laser photocoagulation treatment in diabetic retinopathy

    ObjectiveTo investigate the clinical outcome and therapeutic efficacy of short-pulse pattern scan laser (PASCAL) photocoagulation for diabetic retinopathy (DR). MethodsForty-three DR patients (70 eyes) including 19 males (32 eyes) and 24 females (38 eyes) underwent short-pulse PASCAL pan-retinal photocoagulation (PRP). There were 24 patients (42 eyes) with proliferative diabetic retinopathy (PDR) and 19 patients (28 eyes) with severe non-proliferative diabetic retinopathy (NPDR). The best corrected visual acuity was better than or equal to 0.1 in 62 eyes, worse than 0.1 in 8 eyes. Diabetic macular edema was found in 18 eyes. Short-pulse PASCAL PRP was applied with multi-spot arrays. Macular edema was treated by PASCAL macular mode (MAC A + MAC B) and/or single spot. Visual acuity and fundus examinations were analyzed at the one-year follow-up procedure. ResultsOne year after short-pulse PASCAL treatment, the final visual acuity was improved in 10 eyes, stable in 53 eyes, decreased in 7 eyes; macular edema was relieved in 38 eyes, aggravated in 12 eyes, and stable in 20 eyes. Of 42 eyes with PDR, neovascularization were regressed in 20 eyes, uncontrolled in 11 eyes which experienced additional photocoagulation (1-2 times) during the follow-up. Among the 11 uncontrolled eyes, 3 eyes (3/11) received vitrectomy due to vitreous hemorrhage. ConclusionPASCAL might stabilize the progress of diabetic retinopathy safely and effectively.
