Abstract

Purpose: To determine the central and peripheral choroidal thickness in eyes with central serous chorioretinopathy (CSC) and to compare these thicknesses values with those of control normal eyes.

Methods: Wide-field optical coherence tomographic images of 24 eyes of 19 patients with CSC and 14 normal eyes of 7 individuals were recorded. A 20-mm vertical scan through the fovea was obtained with the Xephilio optical coherence tomographic S1 (Canon, Japan), a wide-field optical coherence tomographic device. The subfoveal choroidal thickness and the thickness at 5 mm superior (S5) and inferior (I5), 7 mm superior (S7) and inferior (I7), 8.5 mm superior (S8) and inferior (I8), and 10 mm superior (S10) and inferior (I10) from the fovea in the CSC eyes and normal eyes were compared.

Results: There was no significant difference in the age ( P = 0.8) or the refractive error ( P = 0.7) between the CSC and normal eyes. The choroidal thickness was significantly thicker in the eyes with CSC than that in the normal eyes at subfoveal choroidal thickness ( P < 0.01), S5 ( P = 0.01), and S7 ( P = 0.02). However, there was no significant difference in the choroidal thickness at the more peripheral points (all P > 0.1).

Conclusion: The thickened choroid in CSC was observed at the fovea and the area just superior to the fovea. The pathogenesis of CSC may be associated with the choroidal thickening confined to the fovea and superior foveal area.

中枢性浆液性脉络膜视网膜病变眼的宽视场光学相干断层扫描测定周围脉络膜厚度。
目的:测定中枢性浆液性脉络膜视网膜病变(CSC)眼的中央和周围脉络膜厚度,并与正常对照眼进行比较。方法:记录19例CSC患者24只眼和7例正常人14只眼的宽视场光学相干层析成像。使用宽视场光学相干层析成像设备Xephilio光学相干层析成像S1 (Canon, Japan)获得通过中央凹的20毫米垂直扫描。比较了CSC眼与正常眼距中央窝上(S5)下(I5) 5 mm、上(S7)下(I7) 7 mm、上(S8)下(I8) 8.5 mm、上(S10)下(I10) 10 mm的脉络膜厚度。结果:在年龄(P = 0.8)和屈光不正(P = 0.7)方面,CSC与正常眼无显著差异。在中央凹下(P < 0.01)、S5 (P = 0.01)和S7 (P = 0.02)处,CSC眼的脉络膜厚度显著高于正常眼(P < 0.01)。然而,更多外围点的脉络膜厚度差异无统计学意义(均P > 0.1)。结论:CSC的脉络膜增厚主要发生在中央窝及中央窝上方。CSC的发病机制可能与局限于中央窝和上中央窝区的脉络膜增厚有关。
