The Tonopen digital tonometer
The Tonopen is a digital tonometer. This device measures intraocular pressure (the pressure inside the eye) which is the way we test for glaucoma. This instrument is digital, painless, and provides accurate diagnostic readings.
Glaucoma is a disease in which the pressure inside the eye gets high. There is constant production of fluid inside the eye, and it normally leaves the eye thru drainage areas at the same rate it is formed, thus maintaining a consistent pressure. If the drainage areas are blocked for any reason, then the pressure can increase rapidly in the eye.
Glaucoma is common in certain breeds of dogs, especially Beagles and Cocker Spaniels. If it is detected very early, it is treatable. However, if the disease goes undiagnosed, it can lead to permanent blindness. It is vital to have such technology available for our patients to ensure the most accurate diagnosis we can.
