Temporal contrast sensitivity in central serous choroidopathy.

Temporal contrast sensitivity (TCS), a function of foveal sensitivity to sinusoidally modulated stimuli, was measured in 35 patients with central serous choroidopathy. Attenuation of the sensitivity at high temporal frequency was observed even when visual acuity was not impaired. In patients whose visual acuity was impaired, attenuation of the sensitivity of middle and/or low frequency as well as at high frequency was observed. In many cases TCS recovered to various degrees as the condition improved, even when little recovery of visual acuity was observed.
