10 Surprising Reasons Your Dog's Eyes Are Swollen

7. Autoimmune Disorders

Autoimmune disorders, where the body's immune system mistakenly attacks its own tissues, can also cause swollen eyes in dogs. Conditions like uveitis, where inflammation affects the uveal tract of the eye, can lead to significant swelling and pain. Autoimmune disorders can be challenging to diagnose as symptoms often overlap with other conditions. A comprehensive examination and blood tests are typically required to identify these disorders. Treatment focuses on managing symptoms and suppressing the immune response using medications like corticosteroids or immunosuppressants. Regular monitoring and adjustments in treatment plans are essential to manage these chronic conditions effectively.

8. Parasites and Their Effects

Parasites such as ticks, mites, or certain worms can also lead to swollen eyes in dogs. These parasites can cause direct irritation or transmit diseases that affect the eyes. For instance, thelazia, a type of eyeworm, can infest the eye and cause significant discomfort and swelling. Symptoms of parasitic infections include redness, discharge, and itching. Treatment involves removing the parasites and administering appropriate medications to address any secondary infections or inflammation. Preventive measures, including regular parasite control and avoiding environments where parasites are prevalent, can help protect your dog from these uncomfortable conditions.
