Actually, the machine used could be one of several: a GDx, and HRT, or an OCT if looking at the optic nerve.  If you were wrong and they were measuring the thickness of your cornea, then they would have used a corneal pachymetry unit.  The thickness of the cornea is relevant in measuring the IOP, as an overly thin cornea will be easier to flatten, giving a falsely low IOP reading, and a thick cornea is harder to flatten, giving an artificially elevated reading.  The thickness of the optic nerve (really the nerve fiber layer just around the nerve) tells us about  nerve damage undetectable to the observing physician’s eye.  More importantly, it shows us if progression is occuring when these tests are done on an annual basis.

I’ve had the thickness of my cornea tested, but not the test you mentioned. The cornea thickness test involved drop to numb my eye and then something (that kinda reminded me of a headphone jack) was pressed into my eye.  I did not like this test. David

Thanks for all the good info. I’m sure now they used the GDx. Angelika

I went to my eyedoc yesterday, pressure in both eyes 28 (I am taking Cosopt and Xalatan, hat ALT surgery once, didn’t keep pressure down long, visual field normal, nerve healthy – so far) and naturally doc is concerned, was even considering trab surgery. He did another test, just had gotten the machine to test the thickness of the optical nerve. The technician couldn’t tell me anything about name of machine, scientific name of test etc. Has anybody had this done? I had to look at a screen with red lines and a dot in it, no drops, pain, discomfort and the result was good! So for now I continue with the drops, have pressure checked every 4 months. Angelika

The machine is likely to be a GDx nerve fibre analyzer or a GDx VCC (Variable Cornea Compensator) (see http://www.laserdiagnostic.com/products/default.asp for information from the supplier). http://www.glaucoma-detection.co.uk/ for better patients’ information. http://willsglaucoma.org/supportgroup/chat08232000.html is a link to the Chat Highlights for the GDx Discussion.
