If the pressure is too high, it can indicate glaucoma; if it's too low, it can indicate uveitis (inflammation in the eye). We are hoping to get a tonometer full-time at the Center for Birds of Prey's Raptor Clinic, after which we will add it to our normal eye exam process. | Audubon Center for Birds of Prey | Facebook
