Scleral injection in dogs, often manifested as redness in the whites of their eyes, can be a concerning symptom for any pet owner. This redness indicates dilated blood vessels within the sclera, the tough, white outer layer of the eye. While not a disease in itself, scleral injection can be a sign of various underlying health issues, ranging from minor irritations to severe ocular conditions. Understanding the potential causes and treatments is crucial for providing your canine companion with the best possible care.
Understanding Scleral Injection in Dogs
Scleral injection can occur in one or both eyes and may be accompanied by other symptoms such as discharge, squinting, or pawing at the eye. It’s important to distinguish scleral injection from other forms of eye redness, like blood in the anterior chamber (hyphema) or inflammation of the conjunctiva (conjunctivitis). While a pet owner might initially observe the redness and suspect scleral injection, a definitive diagnosis requires a thorough veterinary examination.

Common Causes of Scleral Injection
Several factors can contribute to scleral injection in dogs. Some common causes include:
- Allergies: Just like humans, dogs can experience allergic reactions that affect their eyes. Environmental allergens like pollen, dust, and mold can cause inflammation and redness.
- Infections: Bacterial, viral, or fungal infections of the eye can lead to scleral injection.
- Glaucoma: This condition, characterized by increased pressure within the eye, can cause redness and pain.
- Uveitis: Inflammation of the uvea, the middle layer of the eye, is another potential cause of scleral injection.
- Trauma: Injury to the eye, such as a scratch or foreign body, can result in redness and inflammation.
- Dry Eye (Keratoconjunctivitis Sicca): Insufficient tear production can irritate the eye, leading to redness and other symptoms.
Diagnosing and Treating Scleral Injection
If you notice scleral injection in your dog, it’s essential to seek veterinary attention. The veterinarian will perform a complete eye exam, including checking the intraocular pressure and examining the structures of the eye. Further diagnostic tests, like blood work or corneal staining, may be necessary to determine the underlying cause. Treatment depends on the diagnosis and can range from eye drops for allergies or infections to surgery for conditions like glaucoma.
When to Seek Emergency Veterinary Care
While scleral injection isn’t always an emergency, some situations warrant immediate veterinary attention. These include:
- Sudden onset of redness: If the redness appears suddenly and is accompanied by pain or other symptoms, seek immediate care.
- Visible trauma: Any injury to the eye requires prompt veterinary attention.
- Changes in vision: If your dog seems to be having trouble seeing, it’s crucial to seek immediate care.
Preventing Scleral Injection
While not all causes of scleral injection are preventable, some steps can help reduce the risk:
- Regular eye exams: Early detection of eye problems can prevent them from becoming more serious.
- Allergy management: Identifying and managing allergies can help prevent eye irritation.
- Eye protection: Consider using eye protection for dogs engaging in activities that could lead to eye injuries.
Conclusion
Scleral injection in dogs can be a sign of various underlying conditions. Prompt veterinary diagnosis and treatment are crucial for protecting your dog’s vision and overall health. By understanding the potential causes and taking preventative measures, you can help ensure your furry friend enjoys clear, comfortable vision for years to come. Remember to consult your veterinarian for any concerns regarding your dog’s eye health.
