Dr Ashish Markan on Instagram: "The Goldmann applanation tonometer measures intraocular pressure (IOP) by determining the force needed to flatten a specific area of the cornea. This force is then converted to a pressure reading, with 10 times the flattening force (in grams) equaling the IOP in mmHg. The tonometer uses a prism that contacts the cornea, and a split-image prism highlights the tear film meniscus. The IOP is read when the meniscus arcs just touch, indicating the 3.06 mm applanated ar

BIOLOGY | MEDICAL | HEALTH on Instagram: "Doctors detect eye pressure, also called intraocular pressure (IOP), using a tonometry test. There are two main methods: non-contact tonometry, which uses a puff of air to measure how much your cornea moves, and applanation tonometry, which involves numbing the eye with drops and gently touching the cornea with an instrument to measure the force needed to flatten it.
