Presentation
Type III WS (Klein-Waardenburg syndrome, with abnormalities of the arms) is an extreme presentation of type I; some but not all patients are homozygotes. [scienceopen.com]
Case report A thirty-six year-old African man, born in the Southern part of Libya, presented with congenital deafness and a white forelock. He was noted to have variable-sized hypopigmented and depigmented patches. [ijdvl.com]
Sensorineural hearing loss is present in the majority of people with WS2 (almost 80%), and heterochromia iridum (differences in eye coloring) is present in almost half.[1] Progressive hearing loss has also been reported in some people with WS2.[3] In [rarediseases.info.nih.gov]

Eyes
- Esotropia
Firstly, the 5 year old boy, the youngest of three children of a non-consanguineous couple, was referred for ophthalmological evaluation because of constant esotropia in the left eye. [bjo.bmj.com]
- Strabismus
He had bilateral dark brown irides and strabismus convergens in the left eye (Fig 1, top). The pattern of fundus pigmentation was of a distinctly abnormal type in both eyes. [bjo.bmj.com]
- Lacrimation
In addition, the condition may be associated with unusually low (inferior) openings to the tear (lacrimal) ducts and an increased susceptibility to infections of the lacrimal sacs (dacryocystitis). [rarediseases.org]

Families with WS2A may have the full spectrum of eye findings seen in X-linked ocular albinism I (300500) including decreased acuity, photophobia, nystagmus, translucent irides, hypermetropia, and albinotic fundi with foveal hypoplasia. [disorders.eyes.arizona.edu]
Treatment
Treatment Treatment Options: No ocular treatment is necessary but assistive hearing devices can be helpful. [disorders.eyes.arizona.edu]
Treatment may include the use of hearing aids and/or cosmetic products or treatments (if desired) for skin hypopigmentation.[1] Waardenburg syndrome type 2 can be further divided into subtypes based on the genetic cause, when the responsible gene can [rarediseases.info.nih.gov]
Standard Therapies Treatment The treatment of WS is directed toward the specific symptoms that are apparent in each individual. [rarediseases.org]
As no treatment is available for patients with WS 2, prompt diagnosis and referral to a hearing specialist are crucial for the normal development of patients affected with this condition. [ijdvl.com]
