Comparing Two Techniques of Panretinal Photocoagulation on Visual Acuity on Patients with Proliferative Diabetic Retinopathy

We wanted to examine which of two panretinal photocoagulation (PRP)techniques, classical panretinal photocoagulation (CPRP) and modifieldperipheral panretinal photocoagulation PPRP), causes less decline of visualacuity (VA) due to macular edema (ME) in patients with proliferative diabetic retinopathy(PRD). This clinical study includes 180 eyes with PDR with initial papillarneovascularization. The patients were divided into two groups according the RP.PPRP and CPRP showed the decline of VA in all patients, more pronounced in theCPRP group after one week. After three and six months, with CPRP and PPRP thevalues of VA was stabilized. The result suggests that eyes with PDR and startingepipapillar neovascularisation should be treated with PPRP with priority given toCPRP because it caused better VA.
