Retinal nerve fiber layer thickness in congenital color vision deficiency.

摘要

PURPOSE: To evaluate the thickness of the retinal nerve fiber layer (RNFL) in subjects with congenital red-green color vision deficiency (CVD). METHODS: This study included 20 healthy subjects with congenital red-green CVD and 22 healthy subjects with normal color vision. After Ishihara test and examinations visual field by automated perimetry, all individuals underwent scanning laser polarimetry to measure the thickness of the RNFL. RESULTS: All scanning laser polarimetry parameters related to RNFL thickness were found to be similar in subjects with congenital CVD and normal color vision (p>0.05). CONCLUSIONS: This is the first report suggesting normal thickness of the RNFL in subjects with congenital red-green CVD.
