Over the years, not only has our understanding of glaucoma changed but also has changed our approach to the measurement of the IOP. This review is an attempt to elucidate the commonly techniques of tonometry, and critically ev...
متن کاملSchiötz tonometers. An assessment of their usefulness.
THERE is no doubt that applanation tonometry gives more accurate information about the level of intra-ocular pressure than does indentation tonometry. This increased accuracy is due to the fact that applanation readings approach very closely to the levels of pressure in the undisturbed eye (Po), owing to the small volume of fluid displaced by the application of the tonometer (Goldmann, 1957). A...
