title: [Evaluation of contrast sensitivity test in the diagnosis of early glaucoma].
abstract: The static sine grating central contrast sensitivity test was performed in '85 cases (109 eyes) of primary glaucoma (OAG 59 eyes, ACG 50 eyes, visual acuity greater than or equal to 1.0, early cases 81 eyes, and medium and late cases 28 eyes), ocular hypertensives 18 cases (32 eyes), and 55 normal subjects (108 eyes) as controls. The authors found that the central sensitivity function decreased in 94.5% of the glaucoma patients, and the decrease in 88.9% of the early cases was in the high frequency region, and the decrease in low frequency region followed with progress of the disease, with the result that 92.8% of the medium and late cases showed decrease in all frequencies. The OAG and ACG patients did not differ in the CSF drop. 43.8% of the ocular hypertensives also showed high frequency drop in CSF.
