A rare neuro-ophthalmological disorder characterised by a congenital sensory deficit involving all or some of the sensory components of the trigeminal nerve. Due to corneal anaesthesia, it usually presents with recurrent, painless eye infections, painless corneal opacities and/or poorly healing, ulcerated wounds on the facial skin and mucosa (typically the buccal mucosa and/or nasal septum).
