What is corneal ulceration characterized by?

Corneal ulceration is primarily characterized by the disruption of the corneal epithelium, which leads to exposure of the underlying stroma. This process can occur due to various factors such as trauma, infection, or underlying disease, resulting in a defect in the cornea. When the epithelium is compromised, it creates an area that may be more susceptible to further damage and infection, as the protective barrier of the cornea is breached.

Understanding the significance of this condition is crucial, as corneal ulcers can lead to complications such as corneal perforation or scarring if not promptly addressed. Identifying this characteristic can help veterinary professionals diagnose and treat corneal ulcers effectively, preserving vision and ensuring the welfare of the animal.
