The FMAT1 – Tonography, Serial tonometry, Ophthalmodynamometry is a medical device that measures the pressure inside your eye and is used to diagnose and manage glaucoma 

This device is the result of many years of development by Falck Medical, Inc., and has received clearance from the FDA. 

The device is placed on a slit lamp and is used to measure the pressure inside your eye, the resistance of your eye to pressure, and the blood flow in your eye. The four specific measurements taken with this revolutionary device are as follows:  

  1. Tonometry – measures the pressure inside the eye (intraocular pressure or IOP).  
  2. Ocular pulse amplitude – measures the blood flow in the optic nerve and retinal vessels to detect any changes.  
  3. Tonography – measures the resistance of the outflow of fluid from the eye (intraocular pressure). 
  4. Ophthalmodynamometry – measures the blood flow in the ophthalmic artery, which is the main blood vessel supplying the eye. 

The device also uses a disposable prism that prevents the spread of infection. The results of the test can be saved in a digital format and imported into your electronic medical records.
