医源性脉络膜新生血管是激光光凝和其它眼部手术的一个少见的并发症 ,它是各种因素综合作用的结果 ,这些因素包括Bruch膜和 /或视网膜色素上皮的损害。它们的修复过程激发了血管生成因子的释放 ;炎症细胞和脉络膜缺血也是诱发新生血管的因素。它的预后取决于其潜在的眼部疾病和脉络膜新生血管的类型。减少医源性脉络膜新生血管形成的方法包括 :将眼部的激光量降低至最低有效值 ,避免在视网膜同一部位进行反复光凝和尽可能减轻对视网膜色素上皮和脉络膜组织的直接的机械性损伤。
Iatrogenic choroidal neovascularization is a rare complication of laser photocoagulation and other ocular surgeries as a result of a combination of factors including Bruch’s membrane and / or damage to the retinal pigment epithelium. Their repair process triggers the release of angiogenic factors; inflammatory cells and choroidal ischemia are also factors that induce neovascularization. Its prognosis depends on its underlying ocular disease and the type of choroidal neovascularization. Methods to reduce iatrogenic choroidal neovascularization include reducing the amount of laser light in the eye to the lowest effective level, avoiding repeated photocoagulation at the same site of the retina and minimizing direct mechanical damage to the retinal pigment epithelium and choroidal tissue .
