Web1 mrt. 2004 · More recently, pachymetry has become useful in glaucoma detection. The Ocular Hypertension Treatment Study revealed that applanation tonometry of an unusually thin cornea results in a reading lower than the actual IOP because of reduced corneal resistance to indentation. Similarly, thick corneas yield false high readings.
