Changes in visual acuity and contrast sensitivity following macular photocoagulation for clinically significant macular edema: Four month outcomes
Journal Title: Indian Journal of Clinical and Experimental Ophthalmology - Year 2018, Vol 4, Issue 1
Abstract
Threshold severity of diabetic macular edema DME at which initiation of laser treatment is justified was defined as lsquoclinically significant macular edemarsquo CSME by ETDRS Early treatment of diabetic retinopathy study ETDRS showed that macular photocoagulation decreased persistent macular edema and risk of moderate visual loss by 50 in CSME Benefit of treatment generally observed in 34 monthsObjectives To estimate the improvement in visual acuity VA and contrast sensitivity CS at four months following macular photocoagulation in a single arm of Type 2 diabetes patients diagnosed with CSME in a semiurban population of South KeralaMethodology It was a prospective study Descriptive 250 eyes of Type 2 diabetics with CSME were included Focalgrid pattern macular photocoagulation using frequency doubled Nd YAG laser was administered to all participants Improvement in VA was defined as gain by one linemore and decrease by more than two lines was considered as worsening Any dropgain in CS was considered significant Analysed using SPSS 160Results 148 eyes 592 received focal and 102 eyes 408 received grid pattern lasers 242 eyes were included in final analysis VA in 77 eyes 308 was stable improved by one linemore in 134 eyes 536 decreased by lt2 lines in 22 eyes 88 and decreased by gt2 lines in 9 eyes 36 Paired sample ttest to compare VA and CS before and after therapy showed significant improvement plt0001 and plt0001 respectivelyConclusion VA as well as CS showed statistically significant improvement at 4 months following focal grid pattern of macular photocoagulation in CSMEKeywords Clinically significant macular edema Diabetic Retinopathy Photocoagulationnbsp
