Tono-Pen

Dog eye

The Tono-Pen is an electronic tonometer which measures the intraocular pressure of the eye. Intraocular pressure increases when animals have Glaucoma or can increase when there has been trauma to the head. Certain dog breeds are predisposed to Glaucoma, so if Glaucoma is diagnosed early, there is less of a chance of retinal and optical disc damage. Here at Breadner Veterinary Services, we utilize this fast and efficient tool to screen predisposed breeds for glaucoma, monitor patients with existing glaucoma, and test trauma cases. We accept referrals from other veterinary offices if your pet needs ongoing Tono-Pen readings.
