Ocular albinism with late-onset sensorineural deafness

Ocular albinism with late-onset sensorineural deafness (also known as Ocular albinism–sensorineural deafness syndrome or Winship-type ocular albinism) is an extremely rare genetic condition that combines features of ocular albinism with progressive hearing loss that develops later in life. The condition primarily affects two body systems: the eyes and the auditory system. Ocular features include reduced pigmentation of the iris and retina, nystagmus (involuntary eye movements), reduced visual acuity, and foveal hypoplasia, which are typically present from birth or early childhood. The sensorineural hearing loss is progressive and typically manifests in late childhood, adolescence, or adulthood, distinguishing this condition from other forms of albinism. This syndrome was described in a limited number of families, and the underlying genetic mechanism has not been fully elucidated. Unlike the more common X-linked ocular albinism (Nettleship-Falls type), this condition appears to follow an autosomal dominant inheritance pattern based on reported pedigrees. Skin and hair pigmentation are generally normal, with the pigmentary abnormalities being confined to the eyes. There is currently no cure for this condition. Management is supportive and multidisciplinary, involving ophthalmological care (corrective lenses, low-vision aids, sun protection for the eyes), audiological monitoring, and hearing aids or cochlear implants as needed for progressive hearing loss. Genetic counseling is recommended for affected families.
