OCT对高度近视眼继发黄斑劈裂的诊断价值

Dignosis Value of OCT in Macular Retinochises Secondary to Highly Myopia Eyes

目的分析高度近视眼继发黄斑劈裂在光学相干断层扫描(OCT)及其他检查方面的特征。方法回顾分析2002年1月-2006年2月就诊的高度近视眼合并视力下降,临床表现或其他检查均无特征性表现。而用OCT确诊为黄斑劈裂的患者12例20只眼的特征。结果所有患者的OCT图像均表现为典型的黄斑劈裂,劈裂以外层为主,其中2例患眼伴有神经上皮脱离,5例患眼伴有后巩膜葡萄肿。结论OCT对黄斑劈裂具有独特的诊断的价值。

Objective To analyze the features of macular retinoschisis diagnosed by optical coherence tomography （OCT） and others in highly myopia eyes. Methods During January 2002 to February 2006,20 eyes of 12 patients who had low visual activity and high myopia were dignosed as macular retinoschisis by OCT. But these patients have no features of eye clinic and other exam. Results OCT features of all patients were typical retinoschisis and localized in the outer layer of neutosensory retina in macular among them 2 cases accompanied with nerve epithelial detachmento. Conclusion OCT have important dignosis value in macular retinoschises secondary to high myopia.
