目的：了解迁延型中心性浆液性脉络膜视网膜病变(central serous chorioretinopathy，CSCR)的光学相干断层成像(optical coherent tomography ，OCT)特点，从而为我们判断病情、了解预后提供依据。
方法：收集临床确诊的CSCR患者共85例，6mo以上未愈者视为迁延型共32例，6mo内病情痊愈者53例，观察其OCT成像特点并进行比较。
结果：神经上皮浆液性脱离大于500μm、合并色素上皮脱离及健眼存在色素上皮损害的发生率两组之间存在显著性差异，而神经上皮脱离宽度>4 000μm的发生率无统计学差异。
结论：OCT成像简洁、直观，可清晰显示视网膜内各层的细节变化，在诊断、动态追踪方面展示给我们一个全新的视野， 我们可根据OCT的成像特点判断病情，告知预后，为我们临床诊治提供参考。

[Abstract]
AIM:To investigate the features on prolonged central serous chorioretinopathy(CSCR)by optical coherent tomography(OCT)and to provide the basis of deciding the pathogenetic condition and prognosis.
METHODS: Eighty-five patients who had been diagnosed with CSCR were grouped by suffering time as below: 32 patients suffered longer than 6mo as the prolonged and 53 patients with CSCR cured within that time. The imaging features of OCT were compared between the above groups.
RESULTS:The incidence rate of neuroepithelial serous detachment extent above 500μm associated with pigmentary epithelial detachment in suffering eye and pigmentary epithelial damage in contralateral eye was significantly different between two groups. However, the incidence rate of neuroepithelial serous detachment extent above 4 000μm was not significant difference.
CONCLUSION:OCT could display clearly the change of every layer of retina with simplicity and visibility, which supplies us a new horizon to diagnose and trace CSCR. We could decide the pathogenetic condition and prognosis in accordance with the features of OCT, to provide references for the diagnosis and treatment of CSCR.
