retinal detachments
.
Collie Eye Anomaly: How do you treat collie eye anomaly
Unfortunately, there’s no real cure for CEA For dogs that experience setbacks from CEA, such as retinal detachment or holes in layers of the eye (coloboma), surgery may help to minimize the negative effects. There is good news, though – for many dogs, the condition doesn’t worsen enough to cause vision loss at all.
Collie Eye: How do you test a collie eye
Collie Eye Anomaly (CEA) can be easily checked when the puppies are 6-8 weeks old, by a Board Certified Ophthalmologist.

What does CEA look like?
Cea:
