Plain-English summary
A 3-year-old blue-eyed overo paint horse was found to be deaf using a test called brainstem auditory evoked potential, which measures how the brain responds to sounds. The deafness is likely inherited and is linked to the horse's lack of facial color. It's important for potential buyers to have a hearing assessment done, especially for paint horses, during pre-purchase checks. This hearing test is generally easy for the horse to handle and provides reliable results.
Abstract
Deafness was confirmed in a blue-eyed, 3-year-old, overo paint horse by brainstem auditory evoked potential. Congenital inherited deafness associated with lack of facial pigmentation was suspected. Assessment of hearing should be considered, especially in paint horses, at the time of pre-purchase examination. Brainstem auditory evoked potential assessment is well tolerated and accurate.
