脉络膜厚度与特发性黄斑裂孔发病关系的研究进展

Research progress of the relationship between choroidal thickness and idiopathic macular hole

特发性黄斑裂孔(idiopathic macular hole,IMH)是一种黄斑中心凹全层解剖缺陷的老年性视网膜疾病,严重影响老龄患者的中心视力与生活质量。最近的研究发现脉络膜局部血流状况和脉络膜厚度的改变可能与IMH的发病密切相关。光学相干断层深度增强成像(EDI SD-OCT)是一种精确测量脉络膜厚度的新方法,为阐明黄斑裂孔的发病机制提供了新的途径。本文将针对OCT测量的脉络膜厚度与IMH发病关系的最新研究进行综述。

Idiopathic macular hole is a full - thickness defect of retinal tissue involving the anatomic fovea and affecting central visual acuity and quality of life in elder patients. Recent evidence showed that the alterations of choroidal blood flow and choroidal thickness are associated with the formation of macular holes. Enhanced depth imaging spectral-domain optical coherence tomography （EDI SD-OCT） enables in vivo measurement of choroidal thickness and may provide new insight into the understanding of pathogenesis of idiopathic macular hole. In this article, we reviewed current studies on the relationship between choroidal thickness measured by optical coherence tomography and the pathogenesis of idiopathic macular hole.
