Pet Corneal Endothelial Dystrophy

CED is edema (fluid buildup) in the cornea. It varies in severity and presentation.

What are the clinical signs of Corneal endothelial dystrophy?

This type of dystrophy is observed clinically as a progressive corneal cloudiness, typically starting laterally. Over months to years, the entire cornea becomes edematous and severely limits vision. Pain can occur in the late stages due to inflammation and/or corneal ulcers.

What causes Corneal endothelial dystrophy?

Endothelial dystrophy is more common in certain breeds (Chihuahua, Boston terrier, Dachshund), but any breed can be affected. It is caused by abnormal function of the inner layer of the cornea, the endothelium. Similar signs can be seen due to inflammation of this layer as well.

What is the treatment for Corneal endothelial dystrophy?

Surgical grafting is recommended before your pet’s vision is significantly affected. Surgery consists of advancing the scleral conjunctiva over portions of the cornea to decrease and slow the corneal edema. The best results are observed when surgery is performed in the earlier stages of the disease.
