Thirteen patients underwent Nagel anomaloscopy. <b><i>Results:</i></b> Normal colour vision was found in almost 20% of patients. Red/green (R/G) CVDs increased as BCVA declined. About 45% of all R/G CVDs were of the deutan type, although protan type CVDs became progressively apparent when moving from the high to the low BCVA group. An additional blue/yellow CVD was noted in about 25% of patients. In 10/13 patients, a pseudoprotanomaly was noted on anomaloscopy. Severe CVDs leading to scotopization were noted in patients with low BCVA and/or long-standing disease. No statistically significant differences in ERG results were found between groups with or without a CVD. <b><i>Conclusions:</i></b> The degree and type of colour vision deficiency in STD patients correlate better with BCVA than with ffERG results. The presence of specific CVDs may help to establish a diagnosis of STD. A battery of colour vision tests is required to properly evaluate CVDs in STD.
