Observation of the effect of fundus fluorescein angiography for diabetic retinopathy / 中国基层医药

ABSTRACT

Objective To observe the effect of fundus fluorescein angiography(FFA)for diabetic retinopathy (DR).Methods FFA results of 85 cases(161 eyes)were retrospectively analyzed.The distribution of DR,the dis-tribution of non -perfusion (NP),the relationship between diabetic maculopathy (DM)and different DR period were studied.Results The ratios of Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ,Ⅵ of DR were 14.29%,44.72%,34.78%,3.11%,3.11%.NP was found in 69 eyes in 161 DR eyes.The occurrence of NP was highest (81.26%)in nasal,there was NP difference in the distribution of the different quadrants (χ2 =13.931,P <0.01),there were NP differences at different distances from the optic disc.The occurrence of NP was highest (84.06%)in midperiphera.The incidence rates of macular degeneration in Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ,Ⅵ of DR were 8.70%,31.94%,58.93%,80.00%,80.00%.There was correla-tion between DMand DR (χ2 =26.093,P <0.01).Conclusion FFA can provid information for DR severity grad-ing and DM,there were positively correlations between incidence and severity of DM and DR grade,NP was usually occurred at the nasal retina and the midpefipheral retina.
