目的：探讨无黄斑病变近视眼准分子激光原位角膜磨镶术(laser
in situ keratomileusis，LASIK)术后患者黄斑视网膜厚度改变及其与视功能降低的关系。
方法：采用Cirrus高清晰频域光学相干断层扫描(high spectral domain optical coherence tomography， HD-OCT)测量无黄斑病变近视眼LASIK术后患者黄斑视网膜厚度，采用OPTEC 6500视功能检测仪检测对比敏感度(contrast sensitivity function，CSF)，进行相关分析。
结果：黄斑中心凹外(除V1外的黄斑区)不同区域黄斑区视网膜厚度与不同空间频率CSF呈正相关。
结论：本研究表明黄斑中心凹外(除V1外的黄斑区)不同区域黄斑区视网膜厚度变薄，可引起不同空间频率CSF的降低； 不同空间频率CSF可反映中心凹外不同区域黄斑区视网膜功能。

[Abstract]
AIM: To explore the relationship between retinal thickness changes in different macular sections and decrease of visual function in myopia after laser
in situ keratomileusis(LASIK).
METHODS: The retinal thickness in different macular sections of patients after LASIK was measured by Cirrus high spectral domain optical coherence tomography(HD-OCT). The contrast sensitivity function(CSF)was measured by OPTEC 6500. The results were analyzed by correlation analysis.
RESULTS: The retinal thickness in different macular sections outside fovea was positively correlated with the CSF of different spatial frequencies.
CONCLUSION: The decreased CSF of different spatial frequencies results from the changes of retinal thickness at different macular regions outside fovea.
