title: Optic disc coloboma and localized chorioretinal defects in constitutional partial trisomy 8 mosaicism.
abstract: Constitutional partial trisomy 8 mosaicism is a rare chromosomal multisystem disorder with systemic and ophthalmologic manifestations. We report the case of a 15-year-old female mosaic for trisomy 8 who has unilateral colobomatous microphthalmia and multiple chorioretinal defects. These congenital anomalies have not been previously reported in association with constitutional partial trisomy 8 mosaicism.
