Pets, just like their human counterparts, can get glaucoma. The signs can be as vague as a red eye, but may become severe enough to result in a large bulging eye. This is why it important to examine their eyes yearly and check the eye pressure. Fortunately, here at the Animal Place we have an instrument called Tono Pen that measures the pressure within the eye in just seconds! However, for more serious or complex issues, we might refer you to an ophthamologist for further assessment and treatment.
