Comparación del tonómetro de Goldmann, neumotonómetro de contacto y el efecto del grosor corneal

Purpose: To compare the intraocular pressure (IOP) measurements using the Goldmann applanation tonometer (GAT) and contact pneumotonometer (NTC), and to evaluate the effects of central corneal thickness (CCT) on the readings. Methods: This was a prospective, observational clinical study, which included 96 eyes of 49 patients, 40 glaucomatous, 29 ocular hypertensive and 27 normal subjects. The IOP measurements were performed with each tonometer. The CCT was also measured.
