Understanding Collie Eye Anomaly
Collie Eye Anomaly (CEA) is an inherited congenital disease that primarily affects certain dog breeds, including collies, Australian shepherds, border collies, Shetland sheepdogs, and the Lancashire heeler. This condition is caused by a DNA mutation that affects the retina and/or the choroid, leading to various vision defects (Veterinary Partner). In this section, we will delve into the genetic basis of CEA and explore the symptoms and diagnosis of this condition.
Genetic Basis of CEA
CEA is an autosomal recessive condition, meaning affected puppies inherit a copy of the mutated gene from both parents. Puppies with one normal gene and one mutated gene are carriers of CEA, while those with two mutated genes will exhibit symptoms of the condition. Genetic testing can accurately identify carriers with up to 95% accuracy.
It is important for breeders to utilize genetic testing to identify carriers and carefully select mating pairs to reduce the risk of producing puppies with CEA. By understanding the genetic basis of CEA, breeders can make informed decisions to minimize the prevalence of this condition in future generations. For more information on genetic testing for CEA, refer to our article on collie eye anomaly testing.
Symptoms and Diagnosis
CEA can lead to various vision defects, including retinal detachments, choroidal hypoplasia, colobomas, and abnormal vision. Symptoms of CEA may vary in severity and can affect both eyes (Veterinary Partner). While some dogs may have mild visual impairments with blind spots in their visual field, others may experience more significant vision loss and even complete blindness.
Veterinarians can diagnose CEA as early as six to eight weeks of age by examining the eyes for abnormalities such as retinal folds, underdeveloped choroidal blood vessels, and colobomas. Genetic testing can also be used to identify dogs with CEA and determine their carrier status.

In the next section, we will explore the treatment options available for CEA, including laser surgery for retinal detachment and prescription eye medications.
Treatment Options for CEA
While there is no direct cure for Collie Eye Anomaly (CEA), treatment options are available to manage the associated eye problems and preserve vision. These options include laser surgery for retinal detachment and prescription eye medications.
Laser Surgery for Retinal Detachment
In cases where partial retinal detachment is caused by the presence of a coloboma, laser surgery may be attempted to reattach the retina if the condition is detected early. It’s important to note that not all colobomas lead to retinal detachment, especially if the coloboma remains stable during the dog’s first year of life.
The goal of laser surgery is to restore the attachment of the detached retina to the back of the eye. This procedure aims to improve vision and prevent further progression of the detachment. It is typically performed by a veterinary ophthalmologist who specializes in eye surgery.
Prescription Eye Medications
While there is no direct treatment for Collie Eye Anomaly (CEA) itself, prescription eye medications may be prescribed to manage specific symptoms that may develop, such as glaucoma. Glaucoma is a condition characterized by increased pressure within the eye, which can lead to discomfort and vision loss. Prescription eye medications help control intraocular pressure and alleviate the associated symptoms.
The specific medications used will depend on the individual dog’s condition and the severity of the symptoms. It is important to follow the veterinarian’s instructions regarding the dosage and administration of these medications.
It’s worth noting that while treatment options exist, they cannot reverse the underlying Collie Eye Anomaly (CEA). However, with appropriate management and care, many dogs with CEA show minimal to no signs and do not experience vision problems. Regular yearly eye exams are recommended to monitor the progression of the disease and determine the need for treatment (Hill’s Pet Nutrition).
In addition to treatment options, it’s essential for dog owners to understand the importance of genetic testing for breeders and the role of early detection and intervention in managing the condition. By staying informed and working closely with a veterinarian, dog owners can provide the necessary care and support for their pets with Collie Eye Anomaly.
Managing CEA in Dogs
Dealing with Collie Eye Anomaly (CEA) in dogs requires proactive management strategies to ensure the well-being of your furry companion. While there is no cure for CEA, there are steps you can take to monitor the disease’s progression and help your dog adapt to any vision impairments. In this section, we will discuss the importance of yearly eye exams and provide guidance on living with a blind dog.
Yearly Eye Exams
Regular eye examinations are crucial for dogs with Collie Eye Anomaly (CEA). These exams, conducted by a veterinarian, allow for the monitoring of disease progression and the identification of any potential complications.
During the exam, the veterinarian will thoroughly examine your dog’s eyes for abnormalities such as retinal folds, underdeveloped choroidal blood vessels, and colobomas. These visual cues can help determine the severity of CEA and guide treatment decisions. Early detection of any changes is vital in managing the condition effectively (PetMD).
It is recommended to schedule yearly eye exams for your dog, starting as early as six to eight weeks of age. By consistently monitoring your dog’s eye health, you can provide timely interventions and ensure the best possible care.

With patience, consistency, and lots of love, blind dogs can adapt to their surroundings and lead fulfilling lives. It is essential to consult with your veterinarian for additional guidance and support to ensure the well-being of your blind dog.
By prioritizing regular eye exams and providing a nurturing environment for your dog, you can effectively manage Collie Eye Anomaly (CEA) and ensure your furry friend thrives despite any vision challenges they may face.
Preventing Collie Eye Anomaly
Prevention plays a crucial role in managing and reducing the incidence of Collie Eye Anomaly (CEA) in dogs. By focusing on genetic testing for breeders and early detection and intervention, we can work towards minimizing the impact of this inherited condition.
Genetic Testing for Breeders
To prevent the inheritance of Collie Eye Anomaly, it is recommended that breeders obtain puppies from breeders who have certified their breeding dogs to be genetically tested and free of the mutations causing CEA. Genetic testing can identify carriers and affected dogs with up to 95% accuracy (PetMD). By working with breeders who have veterinary ophthalmologist certifications, responsible breeding practices can be ensured, providing additional peace of mind regarding the genetic health of the dog.
A responsible and reputable breeder will prioritize the health and well-being of their breeding dogs and puppies. Genetic testing helps identify dogs that carry the mutated gene responsible for CEA, allowing breeders to make informed decisions about their breeding program. By selecting dogs without the CEA mutation, breeders can gradually reduce the prevalence of the disease in future generations.
Early Detection and Intervention
Early detection and intervention are crucial for managing Collie Eye Anomaly. Regular eye examinations by a veterinary ophthalmologist are essential for identifying signs of CEA and assessing the overall eye health of dogs. These examinations can reveal characteristic symptoms such as choroidal hypoplasia, retinal folds, retinal detachments, colobomas, and vascular defects (Veterinary Partner). Early detection allows for timely intervention, which can help prevent further complications and improve the quality of life for affected dogs.
By combining genetic testing for breeding purposes and regular eye examinations for early detection, breeders and owners can work together to prevent the spread of Collie Eye Anomaly and ensure the overall well-being of the breed.
Preventing Collie Eye Anomaly requires a collaborative effort between breeders, veterinarians, and dog owners. By prioritizing responsible breeding practices, including genetic testing and eye exams, we can reduce the prevalence of CEA in affected dog breeds and promote the long-term health of these beloved companions.
Associated Eye Conditions
Collie Eye Anomaly (CEA) is a genetic eye disorder that primarily affects Collies and related breeds. While CEA itself is a significant concern, there are also associated eye conditions that can impact the vision and overall eye health of affected dogs. In this section, we will explore two of these conditions: cataracts and entropion.
Cataracts in Collies
Cataracts are a common cause of blindness in older Collies. A cataract is characterized by the clouding of the lens in the eye, which can obstruct vision. While cataracts can develop in any dog, Collies are particularly susceptible to this condition.
Surgical intervention is often considered as a treatment option for cataracts in Collies. Cataract surgery involves removing the affected lens and replacing it with an artificial lens, allowing light to properly reach the retina and restore vision. It is important to note that not all cataracts require immediate surgery. The decision to proceed with surgery will depend on factors such as the severity of the cataract and the impact on the dog’s quality of life. Consulting with a veterinary ophthalmologist is essential to determine the best course of action for your dog’s specific case.
Entropion and Surgical Correction
Entropion is another eye condition that can affect Collies, especially due to their hereditary predisposition. In entropion, the eyelid rolls inward, causing the eyelashes to rub against the cornea. This constant contact can lead to corneal damage, discomfort, and potentially vision loss.
Early surgical correction is usually recommended for entropion in Collies. The goal of the surgery is to correct the position of the eyelid, preventing the eyelashes from irritating the cornea. By addressing entropion promptly, the risk of corneal ulcers and more severe complications can be minimized. If you suspect your Collie may have entropion, it is crucial to seek veterinary care to assess the condition and discuss appropriate treatment options.
Understanding and identifying associated eye conditions such as cataracts and entropion is essential for Collie owners. Regular eye examinations by a veterinarian can help detect these conditions early on, allowing for timely intervention.
