观察视网膜脱离复位后的光学相干断层扫描 (opticalcoherencetomography ,OCT)。方法 :34例波及黄斑部的孔源性视网膜脱离复位后的患者分别于术后 3天、 1月、 2月、 3月、 4月、 5月、 6月进行OCT观察 6个月。结果 :术后 3天所有病例均残留程度不等的视网膜下液 ;术后 6月 ,共复位 14例 ( 3例视网膜呈水肿样增厚 ,2例变性 ,1例视网膜下出现新生血管 ,1例黄斑囊样水肿 ,继而发展成黄斑裂孔 ) ;2 0例视网膜下仍有少量残留液体。结论 :OCT可从微观角度直接客观的在活体上检测视网膜的复位状况及组织结构。 (波及黄斑部的 )孔源性视网膜脱离复位后的视网膜下仍有少量残留液体 ,残留液体的长期存在影响术后视功能的恢复。
Optical coherence tomography (OCT) after retina detachment was observed. Methods: 34 patients with rhegmatogenous retinal detachment who had macular degeneration were examined by OCT for 3 months, 1 month, 2 months, 3 months, 4 months, 5 months and 6 months after operation. Results: Subretinal fluid of varying degrees remained in all cases 3 days after operation. In the 6 months after operation, 14 cases were reset (3 cases of edematous thickening of the retina, 2 cases of degeneration, 1 case of retinal neovascularization, 1 Cases macular cystoid edema, and then developed into macular hole); 20 cases still a small amount of residual liquid under the retina. Conclusion: OCT can directly and objectively detect the status of retinal reattachment and tissue structure from the microscopic point of view. (Macular degeneration) of rhegmatogenous retinal detachment is still a small amount of residual liquid after the retina, residual fluid long-term presence of postoperative visual function recovery.
