applanation tonometry

A standard method of measuring the pressure of the fluids within the eye by determining the force necessary to flatten a standard area of the CORNEA. Unduly raised pressure is the hallmark of GLAUCOMA.

Subjects were included in this experiment if baseline intraocular pressure (IOP)wasbelow22 mmHg in both eyes in a Goldmann applanation tonometry examination, findings were normal in slit lamp and funduscopic examinations, and refractive error was within a range of -8.5 to -0.5 diopters (mean of the included subjects: -2.2 [+ or -] 2.0).
Eye examination included best-corrected visual acuity (BCVA) for far and near vision, slit lamp biomicroscopy, IOP measurements with Goldmann applanation tonometry, corneal pachymetry, gonioscopy, dilated fundus examination, and horizontal cup-disc (C/D) ratio evaluation.
