10 Surprising Reasons Your Dog's Eyes Are Swollen

5. Glaucoma and Increased Eye Pressure

Glaucoma, a condition characterized by increased pressure within the eye, can cause significant swelling and discomfort for dogs. This condition occurs when the fluid in the eye is unable to drain properly, leading to pressure buildup. Glaucoma can be primary, due to genetic predisposition, or secondary, resulting from other eye conditions like inflammation or displacement of the lens. Symptoms include redness, cloudiness, and a visibly swollen eye. Untreated glaucoma can lead to permanent vision loss, making early detection and management crucial. Treatment options include medications to reduce pressure and, in some cases, surgical intervention to improve fluid drainage. Regular eye check-ups can help identify glaucoma early, particularly in breeds predisposed to the condition.

6. Tumors and Abnormal Growths

While less common, tumors or abnormal growths around the eye can lead to swelling. These growths may be benign or malignant and can develop in the eyelids, conjunctiva, or within the eye itself. Symptoms vary depending on the tumor's location and size but often include noticeable swelling, changes in eye appearance, and discomfort. A thorough veterinary examination, including imaging and biopsy, is necessary to diagnose the nature of the growth. Treatment depends on the type and stage of the tumor and may involve surgical removal, chemotherapy, or radiation. Early detection of abnormal growths can significantly improve the prognosis and quality of life for affected dogs.
