Armand Imbert (1850-1922) and Adolf Fick (1829-1901) both demonstrated, independently of each other, that in ocular tonometry the tension of the wall can be neutralized when the application of the tonometer produces a flat surface instead of a convex one, and the reading of the tonometer (P) then equals (T) the IOP," whence all forces cancel each other. This principle was used by Hans Goldmann (1899–1991) who referred to it as the Imbert-Fick "l…
WitrynaThe term intraocular pressure is a misnomer. IOP is typically considered to be the pressure inside the eye, but this is mostly incorrect. A better term would be transcorneal pressure difference. Applanation tonometry applies a force outside the eye that equals the force inside the eye (across the cornea) according to the Imbert-Fick principle. phipps robertWitrynaHans Goldmann and Theo Schmidt introduced the Goldmann applanation tonometer (GAT) in 1957.
