Eyelid hyperplasia in dogs is usually caused by damage or infection to the cornea, conjunctiva within the eyelids, or the skin around the eyes. In this case, your dog's eyelids may become swollen, and there may be contaminants or drainage from the eye. In addition to injury or infection, eyelid enlargement in dogs can also be caused by congenital or genetic factors.
For example, some breeds of dogs are born with thicker eyelids, which may lead to eyelid hyperplasia. If you notice growths on your dog's eyelids, it is recommended to take him to the veterinarian immediately. Your veterinarian will perform an evaluation and determine if treatment is needed. If left untreated, eyelid enlargement can lead to eye damage or infection in dogs, and may even lead to blindness.
