目的 :用眼底荧光血管造影 ( Fundus fluorescein angiography,FFA )和吲哚青绿血管造影 ( Indocyanine greenangiography,ICGA)观察黄斑部结节性脉络膜炎 ( Nodular m acular choroiditis,NMC)的荧光特征。方法 :对 19例 2 1只 NMC患眼作裂隙灯眼底检查、 FFA及 ICGA检查 ,并对两种不同的眼底造影进行比较和分析。结果 :1活动期的 16只眼中 ,眼底均表现黄斑部黄白色隆起的结节 ,结节周围多伴有视网膜下出血及轻度渗出 ,FFA显示明显染料渗漏 ,而 ICGA早期表现为充盈迟缓 ,中晚期才见染料渗漏 ;2 3只眼在 FFA表现为单灶性渗漏而 ICGA则表现为多灶性渗漏 ;3 2只眼 ICGA晚期在结节处的强荧光斑外再出现一强度稍弱荧光环 ;4愈合期 5只眼中 ,眼底表现为伴有色素沉着的视网膜下疤痕 ,FFA及ICGA显示这些部位表现为低荧光或着染。结论 :活动期的 NMC,ICGA能更准确显示病灶大小 ,并能显示 FFA和眼底检查未发现的活动病灶
Objective: To observe the fluorescence characteristics of macular nodular choroidalitis (NMC) by fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA). Methods: Twenty-nine eyes of 21 eyes with NMC were examined by fundus examination, FFA and ICGA, and compared and analyzed two different fundus pictures. RESULTS: In the 16 eyes of 1 active stage, the fundus showed nodules with yellowish-white uplift of the macular area. Most of the nodules were accompanied by subretinal hemorrhage and mild exudation. FFA showed obvious dye leakage, while ICGA showed filling early Delayed, late see only dye leakage; 23 eyes in FFA showed a single focal leakage and ICGA showed multifocal leakage; 32 eyes of ICGA in late nodules at the strong fluorescence spot extra A slightly weaker fluorescent ring appeared. In the 5 healed eyes, the fundus showed subretinal scar with pigmentation. FFA and ICGA showed that these parts showed low fluorescence or staining. CONCLUSION: NMC and ICGA in active stage can show the size of lesion more accurately, and can display the active lesion not found in FFA and fundus examination
