Waardenburg’s syndrome /vär′den·bərgz/ [Petrus Johannes Waardenburg, Dutch ophthalmologist, 1886–1979] , a group of conditions related to an autosomal-dominant disorder. The syndrome is characterized by wide bridge of the nose resulting from lateral displacement of the inner canthi and puncta; pigmentary disturbances, including white forelock; different colors in the iris of the eye; white eyelashes; localized loss of pigmentation of the skin; and sometimes cochlear deafness. There are four known types.
