Abstract:
Background Retinal photocoagulation iconsidered to be an effective therapy fodiabetiretinopathy (DR).Fundufluorescein angiography (FFA) iused to determine if panretinal photocoagulation (PRP) ineeded.SometimeFFiunsuitable fosome Dpatients,and funduphotography igenerally applied.However,whethecolofunduphotography can substitute foFFin evaluating Dgrading and advising foadministering the photocoagulation protocol iunclear.Objective Thistudy wato compare the grading outcomebetween colofunduphotography and FFin assessing DR.Methodprospective case serieself-controlled study wadesigned.Thiclinical study waapproved by the EthiCommittee of Shanghai Tenth People'Hospital,and written informed consenwaobtained from each patienprioto entering the series.Five 50° non-stereoscopiphotographwere taken in 238 eyeof 136 patientwho methe criteriof type 2 diabetes,and then the FFwaperformed.The imagewere analyzed based on the 2003 International DiabetiRetinopathy Disease Severity Scale.The comparison of the grading outcomein assessing Dbetween colofunduphotography and FFwaevaluated by the Kappagreementesusing SPS17.0.ResultFunduphotography showed mild non-proliferative D(NPDR) in 17.2％ of case(41/238),moderate NPDin 20.2％ of case(48/238),severe NPDin 27.7％ of case(66/238) and PDeyein 34.9％ of case(83/238).FFshowed mild NPDin 20.2％ of case(48/238),moderate NPDin 17.6％ of case(42/238),severe NPDin 19.3％ of case(46/238) and PDin 42.9％ of case(102/238).The concordance foDgrading between funduphotography and FFwasubstantial (κ =0.653,P＜0.01).In evaluating whetheiwanecessary to administePRP (to severe NPDand PDpatients),good concurrence waobserved between funduphotography and FF(κ=0.812,P＜0.01).ConclusionThe merge image from five 50° non-stereoscopiphotographpresentagood indicatofothe selection of PRP in Dpatientwith type 2 diabetes.However,the physicianshould be cautiouin the evaluation of retinal non-perfusion areand neovascularization by funduphotography.
