Color matching and Stiles-Crawford effect in central serous choroidopathy.

Abstract

Color matching and Stiles-Crawford effect measurement were performed in 3 patients with central serous choroidopathy, 2 normal and 1 deuteranomalous trichromats. The color matches in the affected eye of each patient were displaced to red and could be explained by the hypothesis that the visual photopigments are in reduced optical density due to receptor disorientation caused by serous elevation of the sensory retina. The Stiles-Crawford effects of the affected eyes was abnormal confirming the hypothesis of receptor disorientation. The type III color defect accompanied by pseudo-protanomaly ascribable to receptor disorientation as occurs in central serous choroidopathy may be differentiated from the type III defect without pseudo-protanomaly.
