Testing for glaucoma through the eyelid

The Diaton tonometer (BiCOM), a non-invasive and painless way to measure intraocular pressure (IOP) through the eyelid, has been showcased by Phycon Medical at the 2009 meeting of the Florida Osteopathic Medical Association (FOMA).

The tonometer, which utilizes trans-palpebral and trans-scleral technology and does not require anaesthesia or sterilization, is a hand-held portable device, shaped like a pen. It is designed to be used in both out-patient and in-patient settings by general as well as specialized ophthalmology practitioners, and its manufacturer hopes that the painless technology will aid with mass glaucoma screenings. Because it is non-invasive, it is also possible to use the Diaton tonometer several times during the day, allowing accurate monitoring of treatment efficacy.

The technique received gold medals at both the International Exhibition of Innovation Research and New Technology meetings in Brussels and Geneva.
