目的 探讨老年性黄斑变性 (AMD)视网膜脉络膜血管吻合 (RCA)与视网膜色素上皮脱离(PED)的关系。 方法 回顾分析 2 0 0 0年 10月～ 2 0 0 3年 12月诊治的渗出型 AMD患者 70例 75只眼的光相干断层扫描 (OCT)和眼底血管造影检查资料 ,观察有无 RCA形成以及与 PED发生的关系。 结果 75只渗出型 AMD患眼中 ,34只眼有 RCA形成 ,占 4 5 .3% ;4 1只眼未见 RCA,占 5 4 .7%。有 RCA形成同时存在 PED者 30只 ,占 88.2 % ;不伴有 PED者 4只眼 ,占 11.8%。无 RCA形成但存在 PED者 33只眼 ,占 80 .5 % ;不伴有 PED者 8只眼 ,占 19.5 %。有无 RCA形成的患眼 PED的发生率比较 ,差异无显著性的意义 (χ2 =0 .83,P=0 .5 2 90 )。无 RCA形成的 33只 PED患眼中 ,发生 PED裂孔者 17只眼 ,占 5 1.5 % ;有RCA形成的 30只 PED患眼中 ,发生 PED裂孔者 2 6只眼 ,占 86 .7% ,二者比较 ,差异有显著性的意义(χ2 =8.96 12 ,P=0 .0 0 30 )。 结论 RCA形成在渗出型 AMD患眼中并不少见 ;RCA多与 PED并存 ,但两者之间无直接的因果关系 ;PED裂孔发生与 RCA形成密切相关。
Objective To evaluate the correlation between retinal-choroidal anastomosis (RCA) and pigment epithelium detachment (PED) secondary to exudative age-related macular degeneration (AMD). Methods From October 2000 to December 2003, 75 eyes of 70 patients with active exudative AMD underwent OCT, fluorecein and/or indocyanine green angiography (FA/ICGA) examinations were analyzed to ascertain whether there was RCA. The correlations between RCA and PED were evaluated. Results Of 75 eyes with exudative AMD, 34 eyes (45.3%) had RCA, 41 eyes (54.7%) had no RCA. Among the eyes with RCA, 30 eyes (88.2%) had PED, the remaining 4 eyes (11.8%) had no PED. Among the eyes without RCA, 33 eyes (80.5%) had PED, and 8 eyes (19.5%) had no PED. There was no significant difference in the incidence of PED between eyes with or without RCA (χ~2=0.83, P=0.5290). PED tear was found in 17 eyes (51.5%)out of 33 eyes with PED and without RCA, but in 26 eyes (86.7%) out of 30 eyes with both PED and RCA. There was a significant difference in the incidence of PED tear between eyes with or without RCA (χ~2=8.9612, P=0.0030). Conclusions RCA is not uncommon in exudative AMD. It often coexisted with PED, but there is no direct correlation between them. PED tear is highly correlated with RCA formation.
