Update on surgical management of corneal ulceration and perforation.

Corneal ulcerations are a medical emergency, and in recalcitrant cases, leading to perforation, a surgical ophthalmological emergency. The urgency of the treatment is dictated by the necessity of preventing complications that can lead to serious ocular morbidities. Medical treatment represents the first therapeutic approach and is a defining step in the further management of a patient with corneal ulceration. Multiple surgical strategies are available, but the option depends on the etiology and parameters of the ulceration: size, depth, and location.
