Visual acuity and colour vision tests--a preliminary report.

Abstract

Results are reported of a preliminary survey of colour vision changes in fifteen patients with central serous retinopathy. Colour vision was monitored with the HRR plates, 100-hue test and Nagel anomaloscope. In those patients revealing an acquired dyschromatopsia the defect had a tritan-like response. However, diagnosis is made difficult because of the positively correlated trend between 100-hue error score and visual acuity.
