What defines a simple or uncomplicated corneal ulcer?

A simple or uncomplicated corneal ulcer is defined by its ability to heal within a week without complications. In veterinary ophthalmology, these types of corneal ulcers are typically superficial and limited to the epithelium, allowing for quicker resolution when appropriate treatment is initiated. Factors contributing to uncomplicated ulcers include adequate tear production and proper eyelid function, which help protect the cornea during the healing process.

In contrast, ulcers that do not heal properly, show signs of infection, or require surgical intervention, are classified as complicated corneal ulcers. These may involve deeper structures of the cornea, could be associated with underlying disease processes, or might be exacerbated by factors like bacterial infections, making their management more complex. Thus, the characteristic of healing within a week is crucial in distinguishing uncomplicated corneal ulcers from those that require more intricate care or intervention.
