The Color Vision Test in Acute Central Serous Chorioretinopathy

ABSTRACT

PURPOSE: To evaluate the usefullness of color vision test for early detection of abnormal choroidal circulation of central serous chorioretinopathy (CSCR) METHODS: We investigated the color vision defect in central serous chorioreinopathy at active and resolved phase on both eyes and to identify the relation between fluorescein angiography (FAG), indocyanine green angiography (ICGA) finding and color vision defect. We examined the color vision with the Neitz anomaloscope OT-II, Farnsworth-Munsell 100-hue test, Ishihara pseudoisochromatic plate in 72 eyes of typical acute CSCR patients. We also performed ICGA in 13 eyes revealed color vision defect in fellow eye and 13 eyes not revealed color vision defect in fellow eye at resolved phase. RESULTS: Dyschromatopsia was detected in CSCR at active and resolved phase on both eyes. Most of them showed blue-yellow color defect. Location of leaking point was associated with red-green color defect in active affected eyes. Dyschromatopsia of fellow eyes at resolved phase was associated with abnormal choroidal circulation on ICGA finding. CONCLUSIONS: We suggest that color vision test, as a non-invasive screening test, might be useful for early detection of abnormal choroidal circulation of CSCR.
