What Causes Corneal Edema in Dogs

Corneal edema, also known as corneal swelling, is a condition that affects the transparent front part of a dog’s eye, known as the cornea. It occurs when fluid accumulates within the cornea, causing it to become cloudy and opaque. Several factors can lead to corneal edema in dogs, including:

1. Trauma or injury: Any trauma or injury to the eye, such as scratches or foreign objects, can disrupt the normal functioning of the cornea and result in edema.

2. Infection: Bacterial, viral, or fungal infections can cause inflammation and fluid buildup in the cornea, leading to edema.

3. Glaucoma: Increased pressure within the eye, a condition known as glaucoma, can affect the cornea and cause edema.

4. Allergies: Dogs with allergies may experience corneal edema as a result of the body’s immune response to the allergen.

5. Breed predisposition: Certain breeds, such as Boston Terriers and Pugs, are more prone to corneal edema due to their unique eye anatomy.

6. Inherited conditions: Some genetic conditions, like endothelial dystrophy, can lead to corneal edema as the disease progresses.

7. Eye surgery or medications: Certain eye surgeries or medications, if not properly administered, can cause corneal edema as a side effect.
