Collie Eye Anomaly

What is Collie Eye Anomaly (CEA)?

CEA is an eye condition in which there is an underdevelopment or abnormal development of the dog’s eye. CEA can affect the choroid (the vascular layer located at the back of the eye), sclera, retina and the optic disk. In severe cases, this condition can cause retinal hemorrhages or even blindness. Mild cases of this disorder however, do not typically cause the dog extreme vision problems.

Symptoms

There are a few symptoms related to this disease that may help in determining the condition. For instance, abnormal blood vessels, lesions or craters may appear within the eye. If the animal experiences detachment of the retina, blindness may occur. Luckily, this disorder can be detected at an early age, between 5 and 8 weeks old. Thus, it is vital to have your dog’s eyes checked early on.

Causes

CEA is an inherited disease or passed on by the parents. Certain breeds (both small and large breeds) more prone to this disease include:

• Collies
• Shetland Sheepdog
• Lancashire Heeler
• Border Collies
• Australian Sheepdog

Treatment and Prevention

Unfortunately, there is no treatment available to cure CEA. The best prevention method is to simply not breed carriers of the disease. Regardless, it is important to have your pet checked for this condition early on in the dog’s life. When purchasing a pup, be sure to ask your breeder if the pup has been checked for this condition. For further information regarding this disease consult with your family vet.
