Eye Contact Lens 2022 Jul 3;48(7):303-305. Epub 2022 Jun 3.

Department of Ophthalmology (D.N., S.S.M.F.), University of California Los Angeles, Los Angeles, CA; and Department of Ophthalmology (D.N.), Banphaeo General Hospital, Samut Sakhon, Thailand.

Abstract: A 4-year-old boy presented with right neurotrophic corneal ulcer, lagophthalmos, and facial palsy 8 months after neurosurgery for synchronous brain tumors. Initial treatment with topical antibiotics, topical corticosteroids, lubrication, and lateral tarsorrhaphy successfully treated the corneal epithelial defect; however, the cornea continued to demonstrate diffuse epitheliopathy and a dense stromal opacity and remained insensate on Cochet-Bonnet esthesiometry. After a course of topical cenegermin, central corneal sensation normalized, and the corneal epitheliopathy was markedly improved. Read More
