Chemosis (Allergic Blepharitis)
Sudden swelling of the eyelids is an allergic reaction. This is not a serious problem. It is of short duration and improves when the allergen is removed.
The lids appear fluid-filled, soft, puffy and the dog itches and rubs his face. The reaction may be accompanied by hives in which the hair stands out erect in little patches all over the body.
The most common causes are insect bites or ingredients in foods.
Diagnosis is made by physical examination.
Simple cases can be treated with eye drops or ointments containing a corticosteroid prescribed by your veterinarian. Your vet may also suggest an oral antihistamine to reduce the allergic response.
Identifying the instigating allergen and removing it from the environment (if possible) may provide degrees of protection.
Please contact your veterinarian if you have questions regarding this condition.
