Glaucoma is a disease that indicates an increased pressure in the eye. Glaucoma presents itself differently in animals than it does in humans. In animals, if glaucoma is left untreated for even a short amount of time, it can lead to severe pain and blindness. Flannery Animal Hospital uses a Tono-Pen, the same instrument used by human ophthalmologists to check the pressure in your pet’s eye. If your pet displays symptoms such as sensitivity to light, a dilated pupil, or protruding eyes call 845-565-PETS immediately for an appointment.
