摘要
探讨视网膜地形图在中心性浆液性脉络膜视网膜病变（ＣＳＣ）诊断方面的应用价值。方法 对２６例ＣＳＣ患者（２６眼）和２０例正常人（２０眼）行光学相干断层成像（ＯＣＴ）检查，每只眼获得６幅以中心凹为中心的光学切面图像。将６个切面图像转换成伪彩色的视网膜地形图（ＲＭ），分析其形态特征。结果 ＣＳＣ异常分为４种，ＲＭ的变化与ＣＳＣ的严重程度相一致。结论 ＲＭ在ＣＳＣ的诊断和随访观察方面具有较大的临床价值，可以弥补ＯＣＴ光学切面图像的不足。
Objective To evaluate the role of retinal map(RM) with optical coherence tomography(OCT) in the diagnosis of central serous chorioretinopathy(CSC). Methods OCT was performed in 26 patients(26 eyes) with CSC and 20 normal healthy subjects(20 eyes). RM was constructed using 6 radial scans that intersected at the fovea. Results Abnormal RMs in patients with CSC were divided into 4 different kinds. Changes of RM were proportional to the severity of CSC. Conclusion RM has a clinical value in diagnosis and follow-up observation and compensates for shortcomings of across-sectional OCT images.
