What is a corneal ulcer?

It is important to be aware of the structural anatomy of a dog’s eye to understand cornel ulcer better. The eye of the dog consists of three layers, the outermost layer epithelium, the innermost layer descemet’s membrane and the middle layer stroma. Corneal ulcer in dogs starts with the erosion of epithelium and this condition is called as corneal erosion or corneal abrasion. As the erosion progresses to the stroma the condition elevates to corneal ulcer. Furthermore, a deeper erosion of the entire stroma through to the descemet’s membrane is a serious condition and known by the name descemetocele. This condition is considered to be a bit severe as the next possible stage is the descemet’s membrane rupture, which can cause eyeball liquid to leak and even lead to vision loss.

How to diagnose dog corneal ulcers?

Corneal ulcers at the starting stage are hard to detect, this is why it is highly recommended to take your dog to a veterinary care for an eye checkup at least once a month. A veterinarian usually performs a fluorescein test to diagnose the condition, with the test, the fluorescein stain is put on the dog’s eye and the stain adheres to the ulceration.
