The Maklakoff tonometer was an early example of this method, while the Goldmann tonometer is the most widely used version in current practice. [3] Because the probe makes contact with the cornea, a topical anesthetic , such as proxymetacaine , is introduced on to the surface of the eye in the form of an eye drop .
The Schiotz tonometer consists of a curved footplate which is placed on the cornea of a supine patient. A weighted plunger attached to the footplate sinks into the cornea. A scale then gives a reading depending on how much the plunger sinks into the cornea, and a conversion table converts the scale reading into IOP measured in mmHg.
A patient in front of a tonometer. Intraocular pressure (IOP) is the fluid pressure inside the eye. Tonometry is the method eye care professionals use to determine this. IOP is an important aspect in the evaluation of patients at risk of glaucoma. [1]

You hear it from every corner of the earth when you’re a woman of a certain age. “Lift heavy,” say the experts. “Cardio adds years to your life, but weightlifting adds life to your years.”
Reichert investigated the role of neural stem cells in the development of the brain using the fruit fly Drosophila as a model. He discovered a molecular production program followed by stem cells as they develop in the brain. A similar, evolutionary conserved developmental program also plays a role in the formation of the brain in vertebrates
