RESUMEN
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.
RESUMEN
The aim of this study is to elucidate the association of neovascularization in branch retinal vein occlusion (BRVO) combined with major arterial insufficiency (MAI), compared with BRVO alone. The authors retrospectively reviewed the charts, color photographs, and fluorescein angiograms of 304 patients (308 eyes) who had BRVO from 1990 to 2002 at Hanyang University hospital. Patients with BRVO combined with MAI and patients with BRVO alone were differentiated by angiographic appearance. Of the 308 eyes, 12 (3.9%) had neovascularization, all of which were in the 56 eyes of the MAI group for which the neovascularization rate was 21.4%. Neovascularization in BRVO was more strongly associated with the non-perfusion caused by MAI, rather than with the extent of the non-perfusion area that originated from retinal capillary obstruction. MAI is considered as a risk factor for neovascularization and hence could be a prognostic factor.
