title: [Contrast sensitivity study in the fellow eyes of patients with central serous chorioretinopathy].
abstract: In clinical practice, it has been shown that the contrast sensitivity (CS) test is one of the most sensitive visual functional tests. In our experiment, we used a U.S.-made VCTS 60000 CS test plate to test the fellow eyes (20) of 20 cases with unilateral central serous chorioretinopathy (CSC), along with age-matched normal controls. From the control group, we obtained a group of bell-shaped normal CS curves which showed some degree of decrease with age. 40% of the fellow eyes of the patient group showed a slight CS decrease at mid-high spatial frequencies, though other visual functional tests show no abnormality. These fellow eyes may be at risk for CSC. Our experiment, for the first time, showed the possibility of using the CS test as a diagnostic test for subclinical CSC.
