Retinal thickness and perimetric sensitivity in central serous chorioretinopathy.

Purpose: To investigate the relationship between anatomical changes and visual sensitivity in eyes with central serous chorioretinopathy (CSC).

Methods: Twenty-one eyes with CSC were retrospectively studied using optical coherence tomography (OCT) retinal maps, line scan mode, and the Humphrey perimetry central 10-2 program.

Results: Total retinal thickness (TRT), including the neurosensory retina and subretinal fluid, correlated significantly with the sensitivity loss in the corresponding visual field in the central macula within a circle 6 mm in diameter. Differential analysis of the TRT, separating it into neurosensory retinal thickness (NRT) and subretinal thickness (SRT), revealed that only SRT correlated well with perimetric sensitivity at 1°, 3°, 5°, 7°, and 9° from the fovea along horizontal and vertical lines crossing at the fovea.

Conclusions: Visual sensitivity measured with automated static perimetry is further attenuated by increasing distance between the photoreceptor and retinal pigment epithelium (RPE) in areas of serous retinal detachment in eyes with CSC.
