Abstract： 目的应用光相干断层扫描(OCT)对临床诊断为Ⅰ～Ⅳ期特发性黄斑裂孔患眼进行随诊观察,了解其裂孔进展过程及与玻璃体后分离的相互关系. 方法按Gass的临床分期标准,结合OCT图像特征,诊断特发性黄斑裂孔Ⅰ～Ⅳ期未行手术治疗的72只眼,进行OCT随诊检查. 结果Ⅰ～Ⅳ期裂孔分别为23、19、11、19只眼,随诊时间最长43个月(平均13.4个月),每只眼OCT检查次数2～10次(平均4.7次),在随诊期间,Ⅰ期裂孔23只眼,9只眼(39.1%)进展为Ⅱ～Ⅲ期裂孔,2只眼玻璃体后脱离(PVD)后中心凹曲线恢复正常;Ⅱ期裂孔19只眼,13只眼(68.4%)进展为Ⅲ～Ⅳ期裂孔,有1只眼PVD后裂孔自行愈合;Ⅲ期裂孔11只眼,5只眼(45.5%)进展为Ⅳ期裂孔,1只眼12个月后裂孔部分自行愈合.OCT图像显示,玻璃体从黄斑中心凹周围开始与视网膜分离,直至完全后脱离的过程与黄斑裂孔进展过程一致.在随诊期间,15只眼因病程进展接受手术治疗. 结论黄斑裂孔形成和发展与玻璃体后脱离的发生密切相关.OCT可直观显示黄斑裂孔的进展变化,对提供IMH的分期诊断和手术指征有较大帮助.
