Clinical observation of one time short-pulse pattern scan laser pan-retinal photocoagulation for proliferative diabetic retinopathy

Abstract

AIM: To investigate the clinical efficacy and benefit of short-pulse pattern scan laser(PASCAL)photocoagulation for proliferative diabetic retinopathy(PDR).METHODS:Twenty-eight PDR patients(42 eyes)underwent short-pulse PASCAL pan-retinal photocoagulation(PRP)were analyzed.The best corrected visual acuity was ≥0.1 in 36 eyes, RESULTS: All the cases had no pain during the short-pulse PASCAL treatment.One year after treatments,the final visual acuity was improved in 6 eyes,kept stable in 28 eyes and decreased in 8 eyes; neovascularization were regressed in 18 eyes(43%), stable in 12 eyes(29%), uncontrolled in 12 eyes(29%). Five eyes(12%)received vitrectomy due to vitreous hemorrhage.Compared with before operation, retina thickness in central fovea of macula and visual field had no obvious change after one-time PASCAL PRP(P>0.05). CONCLUSION:The one-time short-pulse PASCAL PRP could stabilize the progress of PDR safely, effectively and simply.
