視網膜血管瘤狀增殖

Retinal Angiomatous Proliferation

視網膜血管瘤狀增殖是老年性黃斑部病變各種病型中最難治療的類型，臨床上可分為四期：第I期形成視網膜內新生血管，由視網膜血管產生新生血管；第II 期形成視網膜下新生血管，新生血管進展至視網膜下腔，可造成漿液性視網膜剝離和漿液性視網膜色素上皮剝離；第III 期為脈絡膜新生血管形成；第IV 期形成視網膜脈絡膜血管吻合。由於此病預後不良，診斷確定後應早期加以治療，治療方法包括雷射光凝固治療、玻璃體切除術手術治療、光動力治療、藥物治療包含類固醇藥物及抗血管內皮生長因子藥物和綜合療法等方法，而真正最有效的療法尚待日後的評估。

Retinal angiomatous proliferation is classified into four stages as follows: (1) stage I: intraretinal neovasculariation, (2) stage II: subretinal neovascularization, may be associated with serous retinal detachment and serous retinal pigment epithelial detachment, (3) stage III: choroidal neovascularization, (4) stage IV: retinal choroidal anastomosis. Some treatment methods have been used to treat this disease, including laser photocoagulation, surgical ablation, photodynamic therapy, drug therapy and combination therapy. The most optimal method of treatment needs further evaluation.
