摘要
目的探讨黄斑下脉络膜新生血管膜手术治疗后的远期效果。方法经睫状体平部行闭路式玻璃体切除术后，切开视网膜，取出黄斑下脉络膜新生血管膜瘢痕组织。７例（７只眼）手术前、后均行视力、矫正视力、眼底及眼底血管荧光素造影检查，并进行长期随诊观察。结果随诊观察１年以上，６只眼黄斑下脉络膜新生血管膜消失，１只眼脉络膜新生血管膜复发。６只眼手术后视力均有不同程度增进，其中２只眼视力提高到０．５以上；１只眼视力减退，黄斑机化组织形成；１只眼发生继发性黄斑前膜。结论黄斑下脉络膜新生血管膜手术切除后，大多数眼视力有所提高，视力提高大小与黄斑下脉络膜新生血管膜瘢痕组织对色素上皮及神经上皮的损害程度有关，手术操作对色素上皮及神经上皮的影响亦有一定关系。
Objective To explora the long term effect of surgical removal of submacular neovascular membranes. Methods After pars plana vitrectomy, a small retinotomy technique was used to extract submacular choroidal neovascular membranes in the seven eyes of seven cases. Before and after surgery, the visual acuity, best corrected visual acuity, fundus and fundus fluorescein angiography were examined in all eyes and long term follow up was carried out. Results With more than 1 year follow up, the submacular choroidal neovascular membranes were not noted in six eyes and recurrent in one eye. After surgery, the visual acuity improved differently in six eyes, two eyes of which increased 5 Snellen lines. Only in one eye did the vision decrease with macular organization, and in one eye a secondary epimacular membrane appeared. Conclusion Most of the eyes have their vision improved after the surgical removal of the submacular neovascular membranes. The visual improvement is related to the extent of retinal pigment epithelium and neurosensory retina damaged by the choroidal neovascular membrane scar, and surgical procedure has also some damaging effects on retinal pigment epithelium and neurosensory retina.
