Collie Eye Anomaly (CEA) is a hereditary eye disorder that affects many dog breeds, but particularly Collies and Shetland Sheepdogs. The condition is caused by a genetic mutation that affects their eye’s development, resulting in abnormalities in their retina, choroid, and sclera. Diagnosing CEA can be done through an ophthalmologic exam, which can include a fundus examination, electroretinography (ERG), and/or an ultrasound.
CEA is a serious condition that can cause blindness in affected dogs, and it’s important to have your dog examined by a veterinarian if you think that they could be affected. Early diagnosis and treatment are key to preserving their vision and preventing further damage.
Symptoms of Collie Eye Anomaly (CEA)
Symptoms of Collie Eye Anomaly (CEA) can vary depending on the severity of their condition. Common signs include:
- Vision loss
- Cloudiness
- Eye haziness
- Squinting
- Visible eye defects
In some cases, dogs can also have pain or discomfort in their eyes. If you notice any of these symptoms in your dog, it’s important to have them examined by your veterinarian as soon as possible.
Diagnosing Collie Eye Anomaly (CEA)
Collie Eye Anomaly (CEA) is typically diagnosed through an ophthalmologic exam. This exam could include a fundus examination, which involves looking into their eye to examine its structures; electroretinography (ERG), a test that measures electrical activity in their retina; or an ultrasound, which can help identify abnormalities in their eye.
Stages of Collie Eye Anomaly (CEA)
The stages of Collie Eye Anomaly (CEA) can vary depending on the severity of their condition. Generally, CEA is split into three stages: mild, moderate, and severe.
Mild stage
Mild CEA is associated with a small amount of retinal detachment or thinning, which might not cause any noticeable symptoms in your dog. In this stage, vision loss is usually minimal and the condition can be managed with regular eye exams and monitoring.
Moderate stage
Moderate CEA is associated with more extensive retinal detachment or thinning, which can cause vision loss or other symptoms. In this stage, treatment might include medications to reduce inflammation, laser therapy, or surgery to repair their retina.
Severe stage
Severe CEA is associated with their retina becoming completely detached, which will cause blindness. In this stage, treatment is usually not possible and your dog will need lifelong management to prevent further damage.
Treatment for Collie Eye Anomaly (CEA)
Treating Collie Eye Anomaly (CEA) depends on the severity of their condition. Mild cases might not need any treatment, while moderate and severe cases can need medications, laser therapy, or surgery to repair their retina. In some cases, vision loss can be prevented or slowed with early diagnosis and treatment.
Regular eye exams are important for monitoring the progression of CEA and detecting any changes in their eye.
Preventing Collie Eye Anomaly (CEA)
Preventing Collie Eye Anomaly (CEA) is important for ensuring the health and well-being of your dog. The best way to prevent CEA is to have your dog tested for the genetic mutation that causes their condition before breeding. Responsible breeders should always test their dogs for CEA before breeding because this can help reduce the disorder in future generations.
It’s important to have your pet examined by a veterinarian regularly for any signs of CEA. Early diagnosis and treatment can help preserve their vision and prevent further damage.
