title: [Therapy of neurotrophic keratopathy in trigeminal schwannoma with radiosurgery].
abstract: BACKGROUND
  We present a patient with neurotrophic keratopathy due to a trigeminal nerve neurinoma, who was successfully treated by radiosurgery.
  
  
  METHODS
  A patient was referred to us with recurrent corneal erosions of unknown origin in his left eye. In addition, he suffered from mild hypoesthesia in the distribution of the first branch of the trigeminal nerve. He was started on topical lubricants (hyaluronic acid 0.5%) and antibiotic ointments (gentamycin), but since no corneal healing occurred, a soft contact lens was applied. The patient developed severe corneal neovascularization within four weeks and the contact lens had to be removed. Three months later an MRI scan was performed, which showed an intracranial tumor originating from the first branch of the trigeminal nerve. Neurinoma of the trigeminal nerve was suspected, and this presumed diagnosis was confirmed by fine needle biopsy. The patient underwent radiosurgery seven weeks later. The epithelium closed, the cornea recovered and stayed stable until the last examination 18 months after radiosurgery.
  
  
  CONCLUSIONS
  Radiosurgery is a promising alternative to conventional microsurgery in cases of neurinomas of the trigeminal nerve including neurotrophic keratopathy, to keep or restore vision.
