PURPOSE: To investigate the type and severity of acquired @entity3641 ( @entity3641 ) in molecularly proven @entity6119 ( @entity6119 ) and to establish whether a relationship exists between best-corrected visual acuity (BCVA) and full-field electroretinography (ffERG), and the degree of CVD. METHODS: A retrospective, cross-sectional study of 73 @entity1 with a molecularly proven diagnosis of @entity6119 , who underwent extensive colour vision evaluation, using pseudo-isochromatic and arrangement tests. Thirteen @entity1 underwent Nagel anomaloscopy. RESULTS: Normal colour vision was found in almost 20% of @entity1 . Red/green (R/G) @entity3641 increased as BCVA declined. About 45% of all R/G @entity3641 were of the deutan type, although protan type @entity3641 became progressively apparent when moving from the high to the low BCVA group. An additional blue/yellow CVD was noted in about 25% of @entity1 . In 10/13 @entity1 , a pseudoprotanomaly was noted on anomaloscopy. Severe @entity3641 leading to scotopization were noted in @entity1 with low BCVA and/or long-standing disease. No statistically significant differences in ERG results were found between groups with or without a CVD. CONCLUSIONS: The degree and type of @entity3641 in @entity6119 @entity1 correlate better with BCVA than with ffERG results. The presence of specific @entity3641 may help to establish a diagnosis of @entity6119 . A battery of colour vision tests is required to properly evaluate @entity3641 in @entity6119 .
