[Contrast sensitivity in the fellow eye of unilateral age-related macular degeneration].
The VCTS 6000 Contrast Sensitivity Test System was used in testing the fellow eyes of 20 cases of unilateral age-related macular degeneration (ARMD), with age-matched normal controls. Among the patients, 25% of the fellow eyes showed minor contrast sensitivity reduction at medium and high spatial frequencies. This test may be useful in the diagnosis of subclinical ARMD.
