Indolent corneal ulcers occur in several species and are extremely common in dogs, most often in aged patients as well as the boxer breed. Synonyms for indolent corneal ulcers include superficial corneal erosion, recurrent erosion, boxer ulcers, and refractory corneal ulcers.1-3
In this disease, the corneal epithelium sloughs off of the cornea, often leaving ragged epithelium along the edges of the ulcer (Figure A). The cause of this superficial erosion is unknown; however, it may be related to age or breed and is often spontaneous. While many clients suspect that a particular incident may be related to the start of these ulcers, the ulcers are often spontaneous and the suspected cause usually coincidental.
