The
Collie Eye Anomaly known also as
Choroidal Hypoplasia, is a recessively inherited eye disorder that causes abnormal development of the choroid (a layer of tissue under the retina of the eye). The symptoms and signs can vary greatly among affected dogs within one breed, between parent and offspring and even within a litte.
In its mildest form, there are minor changes in the choroid which will have little effect on sight.
The total retinal detachment will cause blindness.
Even dogs with minor lesions (mild choroidal hypoplasia) should not be bred because their offspring may be affected with more serious forms of the disorder.
The Collie Eye Anomaly/Choroidal Hypoplasia is inherited as an autosomal recessive trait with variable expression and pleomorphism (meaning that there is a wide range in clinical expression of the defect).
In partnership with the Laboratory OPTIGEN (USA), ANTAGENE proposes a DNA test to detect the Collie Eye Anomaly/Choroidal Hypoplasia in following breeds:
• Collie
• Australian Shepherd
• Border Collie
• Shetland
To test your dog for CEA, please feel free to contact us. Further information about Optigen : www.optigen.com
Why to test your dog ?
• to detect very early carrier dog
• to select breeding animals and to adapt breeding strategies
• to avoid producing and selling pups affected by
• to anticipate the apparition of the disease
