Purpose: To describe a case of corneal ulceration associated with Nivolumab use.
Observations: An 80-year-old woman treated with Nivolumab for metastatic melanoma developed an intractable corneal ulcer in her left eye, refractory to all therapies - including surgery to cover the ulcer with a conjunctival flap - until topical prednisolone acetate was tried, which was curative.
Conclusions and importance: Nivolumab use may be associated with a form of steroid-responsive corneal ulceration.
