目得：目的：探讨玻璃体手术后黄斑裂孔闭合的光学相干断层扫描（OCT）特征。方法：前瞻性研究28例（28只眼）特发性黄斑裂孔患者玻璃体手术前后的OCT特征。我们比较了最佳矫正视力水平与术后的断层功能。结果：25眼成功密封黄斑裂孔有两个断层功能之一，在术后1个月内：简单的关闭（正常的中央凹配置）在14只眼睛（56%）或桥形成在中央凹，模仿一个中央凹视网膜脱离在IL眼（44%）。桥组织附着于视网膜色素上皮平均需要2.0个月（范围0.8 - 3.5个月）。前一组的最佳矫正视力迅速提高;后一组的视力在桥组织附着后1个月开始改善。一个封闭的孔重新开放4个月后，在一只眼睛的桥梁formation.CONCLUSIONS：特发性黄斑裂孔有两种模式之一，手术后早期关闭，简单的关闭或桥梁的形成。视觉改善开始后，中央凹采取正常配置。桥的形成似乎反映了黄斑裂孔解剖闭合的早期阶段和脆弱状态。(C)2000年，Elsevier Science Inc.

PURPOSE: To report the optical coherence tomographic features of macular hole closure in the first months after vitreous surgery.METHODS: We studied prospectively the tomographic features of 28 eyes (28 patients) with idiopathic macular holes before and after vitreous surgery by optical coherence tomography. We compared the best-corrected visual acuity levels with the postoperative tomographic features.RESULTS: The 25 eyes with successfully sealed macular holes had one of two tomographic features within 1 month postoperatively: simple closure (normal foveal configuration) in 14 eyes (56%) or a bridge formation at the fovea that mimicked a foveal retinal detachment in Il eyes (44%). It took an average of 2.0 months (range, 0.8 to 3.5 months) for the bridge tissue to attach to the retinal pigment epithelium. Best-corrected visual acuity quickly improved in the former group; visual improvement began 1 month after attachment of the bridge tissue in the latter group. A closed hole reopened 4 months postoperatively in one eye with a bridge formation.CONCLUSIONS: Idiopathic macular holes have one of two patterns early after surgical closure, simple closure or a bridge formation. Visual improvement starts after the fovea assumes a normal configuration. The bridge formation appears to reflect an early phase and fragile condition in the anatomic closure of macular holes.
