Astigmatic reduction after dermoid excision in a child with Goldenhar syndrome

Abstract

Goldenhar syndrome is a rare congenital disorder. Limbal dermoid associated with this syndrome can cause high astigmatism and amblyopia in children. We report significant reduction in astigmatism, after limbal dermoid excision with lamellar keratoplasty, in a rare case of Goldenhar syndrome. A three-year-old female patient, with left-sided limbal dermoid with high astigmatism and amblyopia, was referred to us for visual rehabilitation. The patient had left-sided limbal dermoid and preauricular appendages. Oral examination revealed bifid labial frenum, a deep antegonial notch on the left side of the mandible and missing left upper central incisor teeth. She was diagnosed as a case of Goldenhar syndrome. Her best-corrected visual acuity was 20 of 20 in the right eye and 20 of 200 in the left eye. Refraction showed astigmatism of 10 diopters in her left eye. She underwent limbal dermoid excision with lamellar keratoplasty in her left eye, after which her astigmatism reduced considerably. Early surgical intervention is recommended in cases of limbal dermoid with high astigmatism as it provides not only good cosmetic but also good visual benefits by early institution of treatment for amblyopia.
