ABSTRACT

Objective:To study analyze sthe contrast sensitivity of high myopia.Methods:The contrast sensitivity function(CSF) in 60 eyes of 30 patients with high myopia was studied with normal subjects as control.Those with other ocular disease or systemic disease were excluded to avoid any possible affection.The patients were aged from 12 to 62 years.Corrected vision were all over 0.8 in high myopia,and the control was more than 1.0.The contrast sensitivity function was measured with CSV-1000E Vision Testing Instrument(provided by VECTOR VISION company).Results:The results revealed that the CSF of high myopia in each space-frequency range was decreased.The difference between high myopia group and control group was significant(P
