Do collies have eye problems?
Two inherited eye diseases are of a concern to all collie breeders. The first is called Collie Eye Anomaly or CEA. CEA is a set of physical conditions which are present in the collie prior to birth. When the puppy is just a few weeks old, a canine ophthalmologist can examine the eyes by dilating the pupils with medicated drops and viewing the interior with an ophthalmoloscope. The eye is then graded as either “clear” (non-affected or “normal”) or as “affected.” (It should be noted that there is no standardized rating system or nomenclature that is used by all veterinarians.) CEA is described as: Chorioretinal Change or Choroidal Hypoplasia – changes that affect the central layer of the lining of the eye. Coloboma, Staphyloma, Ectasia – terms referring to a bulging or cupping of the eye, usually in the region of the optic disc. Tortuous Blood Vessels or Vascular Disease – abnormalities in the blood vessels of the eye. Retinal Detachment – Separation of the retinal layer from the wall of
