光学相干断层扫描对黄斑劈裂的观察

目的:加深对黄斑部视网膜劈裂的了解。方法:对2005-01/2007-01间我院进行OCT检查发现黄斑部存在视网膜劈裂的患者进行了进一步的检查和分析。结果:在此期间共有符合入选条件的116眼经OCT诊断为黄斑部视网膜劈裂,其中94眼为病理性近视眼,17眼为先天性遗传性黄斑劈裂,5眼是视乳头小凹。其中视网膜劈裂可发生在视网膜神经上皮层中内、中、外三个部位,其中外层的最常见;不同原因所导致的劈裂其病变的层次和范围也各不相同。结论:黄斑部的视网膜劈裂可发生在视网膜的多个层次,对于其的认识有待进一步加强。

Clinical study of macular retinoschisis

·AIM: To improve our understanding of retinoschisis at the macular area.·METHODS: From January 2003 to January 2005, the patients whose macular retinoschisis was confirmed by optical coherence tomography (OCT) were included in the study. Their data and other results were further analyzed.·RESULTS: During that period, macular retinoschisis was found in 116 eyes which fit the including criteria. Among these, 94 eyes were pathological myopia; 17 were X-linked congenital retinoschisis; and 5 had excavation of optic disk.By analyzing the OCT figures, it was found that retinoschisis could happen at many locations within retinal neural epithelium, including inner, middle and outer part. The retinoschisis caused by different reasons differs in OCT results.·CONCLUSION: Retinoschisis at the macular area was not rare at the clinic, and the retinoschisis may be located at different parts of the retina. OCT was useful in the diagnosis and follow-up of macular retinoschisis.
