Foresight Health® Collie Eye Anomaly


Our Foresight Health® single test for Collie Eye Anomaly is ideal for breeders and owners who want the reassurance of genetic health testing.

The guideline turnaround time for single tests is approximately 10-12 working days after the swab arrives at the lab.

If you need more than two tests it is often more cost-effective to order the relevant Foresight Health® breed package.


Collie Eye Anomaly (CEA) or Choroidal Hypoplasia is an eye disorder caused when the choroid, a layer in the eye, does not develop properly. Symptoms can vary from mild to severe, from almost normal eyes to retinal detachment and ultimately blindness.

Collie Eye Anomaly is an autosomal recessive condition caused by a mutation in the NHEJ1 gene.


This test is also included in the following Foresight Health® breed packages:
