黄斑中心脉络膜新生血管形成通常视力预后较差。根据黄斑光凝研究组(MPS)的随机对照治疗观察,视网膜光凝对某些黄斑中心脉络膜新生血管膜,尤其是复发膜有一定疗效,但视力不可避免地下降。因此作者们探索应用玻璃体视网膜切割技术切除黄斑中心脉络膜新生血管(CNV)。共切除或分离了92眼的 CNV,其中病因为老年性黄斑变性者42眼,组织胞浆菌病综合征者35眼,其它病因5眼。通过短期随诊观察,由老年性黄斑变性引起的黄斑中心CNV 48例中12例视力明显提高(以提高二行或二行以上为标准);病因为组织胞浆菌病综合征者31例中14例视力明显提高;其它病因5例中2例视力明显提高。玻璃体视网膜切割技术切除 CNV 在技术上的可行性为研究 CNV 提供了机会,并为许多黄斑疾病无法恢复视功能者提供了手术治疗的前景。
Macular central choroidal neovascularization usually has poor visual outcome. According to the randomized controlled study of the MPS group, retinal photocoagulation had some effect on some macular choroidal neovascular membranes, especially the recurrent membranes, but visual acuity decreased inevitably. Therefore, the authors explored the use of vitrectomy for the removal of macular central choroidal neovascularization (CNV). A total of 92 eyes of CNV were excised or isolated, of which 42 were caused by age-related macular degeneration, 35 were histoplasmosis and 5 were other etiologies. Through short-term follow-up observation, visual acuity of 12 cases of CNV caused by age-related macular degeneration in 48 cases was significantly improved (to improve two or more rows as the standard); the cause of histoplasmosis syndrome in 31 cases 14 cases of visual acuity was significantly improved; other causes of 5 cases in 2 cases significantly improved visual acuity. Vitreoretinal resection The technical feasibility of resection of CNV provides an opportunity for CNV research and offers prospects for surgical treatment of many patients with macular degeneration who can not recover visual function.
