Collie Eye Anomaly (CEA) in Shetland Sheepdogs
Moderate Risk Category: Eye Typical onset: Birth Hereditary: Yes Est. treatment cost: £200-£1,500
Collie Eye Anomaly (CEA) can affect members of the breed within the Shetland Sheepdog. Common indicators include choroidal hypoplasia (pale areas in retina), colobomas (holes in retinal structures), and retinal detachment. CEA is a hereditary congenital eye defect affecting collie breeds. It ranges from minor choroidal hypoplasia (mild, no vision loss) to colobomas, retinal detachment, and intraocular haemorrhage causing blindness. Severity does not worsen after birth. It typically becomes apparent at Birth. In smaller breeds like the Shetland Sheepdog, early detection and prompt treatment generally lead to better long-term outcomes. This condition has a hereditary component — prospective owners should request documentation of health screening from the breeder. Treatment costs are estimated at £200-£1,500, making comprehensive pet insurance a practical consideration.
