Abstract

Townes-Brocks syndrome (TBS) is a rare genetic syndrome associated with heterozygous mutations in SALL1 and characterized by abnormalities of the anus, ear, and thumb. Ophthalmic findings have been rarely reported and include congenital cataract, microphthalmia, optic nerve atrophy, coloboma, epibulbar dermoid, and dysinnervation patterns, such as Duane syndrome and gustatory lacrimation. We report a case of genetically confirmed TBS showing a spectrum of ocular anomalous innervations, including bilateral type 1 Duane syndrome and Möbius sequence, left-sided Marcus Gunn jaw winking, left eye gustatory lacrimation, and lack of emotional tearing bilaterally. Magnetic resonance imaging of brain and orbit showed absence of the abducens nerve bilaterally and of the left facial nerve.[Formula presented]
