No blue-yellow color vision impairment after acute ethanol ingestion.

Several studies showed that chronic ethanol exposure can cause color vision deficiencies. There has been no agreement about the axis of color defects due to alcohol misuse since changes in the red-green and the blue-yellow axis have been described in literature. The acute influence of alcohol on the blue-yellow color vision has not been studied as well. The aim of this study was to determine the effect of acute alcohol ingestion on blue-yellow color vision by using short wavelength automated perimetry (SWAP) and anomaloscopy with the Moreland equation. This is the first study evaluating that question by using SWAP and anomaloscopy.
