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.
