Abstract
As the Stiles-Crawford (S-C) effect of the first kind depends on the directional sensitivity of photoreceptors, it can be used in clinical research to identify and quantify photoreceptor involvement in retinal diseases. In this report, we describe abnormalities of foveal cone directional sensitivity and foveal cone thresholds in patients with gyrate atrophy of the choroid and retina (GA).
