Acute neurotrophic keratitis with trigeminal trophic syndrome after craniotomy.

We report the case of a child who, shortly after undergoing suboccipital craniotomy for resection of a medullary cavernoma, developed corneal and conjunctival epithelial breakdown of the right eye with ipsilateral facial hypoesthesia as well as erosions and crusting of the eyelids, nostril, and lips on the right side. This combination of findings likely results from acute injury to the ipsilateral trigeminal ganglion, leading to acute neurotrophic keratitis and trigeminal trophic syndrome.
