Audiometric and vestibular abnormalities in macular degeneration.

Audiometric (pure tone audiometry and tone decay) and vestibular examinations (bilateral caloric test and electronystagmography) were carried out in 10 cases of macular degeneration of different types and 10 normal individuals as control. Out of 10 cases of macular degeneration of various types, 3 (30%) showed hearing impairment, while on vestibular examination 3 (30%) also had vestibular abnormalities. Only one case was associated with both audiometric as well as vestibular abnormalities. In the control group none of the individual showed either audiometric or vestibular changes.
