Collie Eye Anomaly (CEA) in Miniature American Shepherds

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 Miniature American Shepherd. 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 Miniature American Shepherd, 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.

Symptoms of Collie Eye Anomaly (CEA) in Miniature American Shepherds

  • Choroidal hypoplasia (pale areas in retina)
  • Colobomas (holes in retinal structures)
  • Retinal detachment
  • Intraocular haemorrhage
  • Blindness in severe cases

If your Miniature American Shepherd is showing any of these signs, consult your veterinarian promptly.

Treatment Options

There is no treatment for CEA. Laser or cryotherapy can be used to stabilise early retinal detachments in go-normal or mildly affected dogs. Most affected dogs adapt well to their level of vision.

Estimated Treatment Cost

£200-£1,500

Costs vary by severity, location, and treatment path. Pet insurance is strongly recommended.
