In many patients some degree of color vision defect remains after CSC even if the VA has recovered to normal. The contralateral eye can also have a color vision defect. This has not been previously reported and might be due to earlier subclinical CSC.
Contrast sensitivity does not seem to recover in all eyes after CSC even if the visual acuity has returned to normal. Therefore, contrast sensitivity testing is recommended for the patients complaining of visual impairment in spite of good visual acuity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
