Unilateral pediatric neurotrophic keratitis due to congenital left trigeminal nerve aplasia with PROSE (prosthetic replacement of the ocular surface ecosystem) treatment

Abstract

Purpose: To present a 3-year-old female patient with a non-familial, isolated, unilateral case of left corneal anesthesia with MRI-confirmed congenital left trigeminal nerve aplasia. Observations: A corneal epithelial defect was noted in the left eye after an 8-week trial of recombinant human nerve growth factor. Subsequent evaluation and fitting of a PROSE (prosthetic replacement of the ocular surface ecosystem) lens led to healing of the corneal epithelium and visual acuity improvement from 20/300 to 20/70. Conclusions and Importance: A scleral lens may be a possible treatment for those with neurotrophic keratitis in which a trial of topical lubrication and human nerve growth factor has not been effective.
