相干光断层成像对病理性近视黄斑区的临床观察

Optical coherence tomography in observing macular area of pathologic myopia

目的探讨相干光断层成像(OCT)在观察高度近视患者黄斑区视网膜各层次结构变化的临床意义。方法对45例(66只眼)诊断为病理性近视的患者进行回顾性研究。全部病例均采用OCT进行扫描,详细分析患者黄斑区的结构变化。结果本组66只眼患者中继发性视网膜劈裂、脉络膜新生血管29只眼,单纯视网膜下出血5只眼,黄斑裂孔6只眼,视网膜前膜6只眼,玻璃体黄斑牵引5只眼,瘢痕16只眼。结论 OCT在观察病理性近视患者黄斑区结构变化中,有着独特的、不可或缺的作用。

Objective To explore the clinical significance in observing macular area of pathologic myopia by optical coherence tomography（OCT）.Methods 45 patients（66 eyes） proved pathologic myopia were subjected to OCT and their changes of macula structure were analysis.Results Among the 66 eyes,8 had secondary retinoschisis,29 had choroidal neovascularization,5 had subretinal hemorrhage,6 had macular hole,6 had epiretinal membrane,5 had vitreomacular traction syndrome,and 16 had retinal scar.Conclusion In observing the changes of structure of macular area in pathologic myopia,OCT has become a kind of essential approach.
