The patient is a 27-year-old man with a constellation of symptoms including progressive, moderate, unilateral sensorineural hearing loss (SNHL) and tinnitus. Physical examination revealed a white patch of hair in the temporal region, one blue iris and one blue iris with a brown irridial patch that covered approximately 50% of the iris, no abnormalities of the medial canthii, and no pigmentary changes of the skin (Fig. 1). Audiograms done over a 5-year period showed progressive hearing loss during the previous 5 years on the left side. The head and neck examination was otherwise within normal limits, and the patient was healthy with a negative review of systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
