{Abstract}: Neurotrophic keratopathy is a rare disorder caused by the loss of corneal sensation. It is characterized by persistent epithelial defects, corneal ulceration, and, ultimately, corneal perforation if not managed in a timely manner. The management includes aggressive lubrication, prophylactic topical antibiotics, therapeutic contact lenses, tarsorrhaphy, and amniotic membrane transplantation. Some novel therapeutic options are also available, one of which is topical insulin therapy. We report the clinical course of a patient with neurotrophic keratopathy that was successfully treated with topical insulin. A 64-year-old male presented to our outpatient department with a three-month history of painless blurring of vision following prior episodes of herpetic keratitis. Ocular examination showed a bilateral reduction in corneal sensations, bilateral corneal opacities, and a corneal ulcer in the left eye. He was diagnosed as a case of neurotrophic keratopathy secondary to prior herpetic keratitis. He was then treated with topical and oral acyclovir along with topical insulin drops. There was a remarkable improvement in his condition after a month with a reduction in the size of the ulcer and, after two months, the ulcer was completely re-epithelialized. This case report illustrates the use of topical insulin in the initial management of neurotrophic keratopathy as opposed to its conventional use in refractory neurotrophic corneal ulcers.
