Goldenhar Syndrome - ophthalmologist's perspective.

Goldenhar syndrome (oculo-auriculo-vertebral dysplasia, OAVS) is a rare, congenital disease arising from the abnormal development of the first and second branchial arches. The incidence is between 1:3500 and 1:5600, with a male: female ratio of 3:2. The etiopathogenesis is multifactorial and dependent on genetic and environmental factors but there are still many unknown aspects. The classic features of Goldenhar syndrome include ocular anomalies - epibulbar dermoids, microphthalmia and coloboma, ENT features such as preauricular tragi, hearing loss, low implantation of the auricular pavilion, micrognathia, and vertebral anomalies such as scoliosis or hemivertebrae. The abnormalities are unilateral in 85% of the cases. Ocular features, especially bilateral dermoids are seen in 60% of the cases. The treatment varies with age and systemic associations, from mainly cosmetic, in uncomplicated cases, to complex reconstructive surgeries in severe cases. While the oculoplastic surgeon manages the oculo-palpebral defects, severe forms require a multidisciplinary approach. Treatment should be individualized, adapted to age, as well as to the extent and severity of the disease. The paper is based on the editorial team cases and experience.
