眼前节全景OCT在白内障术后隐匿性角膜后弹力层脱离应用研究

Clinical application of diagnosis in occult Descemet membrane detachment occurred after cataract operation by anterior segment optical coherence tomography

目的 采用眼前节全景OCT （anterior segment optical coherence tomography,AS-OCT）观察白内障手术后隐匿性角膜后弹力层脱离的发生、位置和范围,为临床诊疗提供依据.方法 对2011年12月至2012年9月间在深圳市眼科医院采用眼前节全景OCT对22例白内障术后出现难治性角膜水肿的术眼进行观察,发现是否存在角膜后弹力层脱离的情况,并确定脱离的部位和累及的范围.结果 发现8例不同程度的角膜后弹力层脱离,其中7例发生在角膜手术切口附近.结论 对白内障术后出现难治性角膜水肿的患者术眼进行眼前节全景OCT检查,有助于发现不同程度的隐匿性角膜后弹力层脱离,制定针对性治疗方案.

Objective To observe the occult Descemet membrane detachment with the anterior segment optical coherence tomography （OCT） after cataract operation,to provide the basis for clinical diagnosis and treatment.Methods Twenty-two patients were examined with Anterior segment OCT after cataract operation,whose eyes were with refractory corneal edema to find where the existence of Descemet membrane detachment and determine the site and scope in Shenzhen Eye hospital during December 2011 to September 2012.Results Eight cases were found with different degrees of Descemet membrane detachment,which occurred near the incisions in 7 cases.Conclusions The examination of Anterior segment OCT to the patients whose eyes are with refractory corneal edema after cataract operation is helpful to find different levels of occult Descemet membrane detachment.
