Corneal ulcers represent one of the most common ocular abnormalities presenting to the general practitioner. It is useful to think about ulcers in two broad categories: complicated and uncomplicated. Under the umbrella of complicated corneal ulcers is a specific type of ulcer called a Spontaneous Chronic Corneal Epithelial Defect (SCCED), sometimes also referred to as an indolent ulcer or Boxer ulcer. Like all ulcers, SCCEDs are painful and can be frustrating to treat, especially because they are frequently misdiagnosed at initial presentation as a routine, uncomplicated corneal ulcer. Unfortunately, client frustration with many weeks of treatment and failure of their dog’s eye to heal often leads to loss of the established client veterinarian relationship and revenue.
