title: Color vision defects after central serous chorioretinopathy.
abstract: OBJECTIVE
  To reexamine patients diagnosed with central serous chorioretinopathy (CSC) during the 10-year period from 1987 to 1996 to identify remaining color vision defects in the eyes with normal visual acuity (VA).
  
  
  METHODS
  Thirty-nine patients were found with normal VA of 20/20 (logMAR 0) or better 8 to 166 months (mean +/- SD, 58.8 +/- 41.2) after active CSC. Color vision was examined with the Standard Pseudoisochromatic Plates part 2, Farnsworth-Munsell 100 hue test, and Color Vision Meter 712 anomaloscope.
  
  
  RESULTS
  Of the CSC eyes, 26 (67%) had a color vision defect, most of them in the blue area. There was no correlation between the time since the active disease and the results on the color vision tests. Of the contralateral eyes, 19 (49%) also had a color vision defect.
  
  
  CONCLUSIONS
  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.
