Estudio comparativo de las propiedades corneales y su influencia en la tonometría portátil de rebote y aplanación en sujetos sanos y pacientes con glaucoma primario de ángulo abierto

Abstract

Primary open angle glaucoma (POAG) is a progressive and multifactorial optic neuropathy considered the second cause of blindness in Europe and in the world.Intraocular pressure (IOP) is the main modifiable factor, that is why the measurements must be reliable and reproducible.In last few years, new devices such as rebound or non-contact tonometry have been developed trying to overcome some of the limitations of conventional tonometry.Rebound tonometry measures IOP thanks to a solenoid magnetic probe that bounces off the cornea the deceleration induces voltage and this value is transformed in the IOP measurement. It does not require the instillation of anesthetic drops, the acquisition of measurements is fast, it requires little collaboration from the patient, it is independent of the position, allowing checking IOP in decubitus, preoperative or intrasurgical examinations. It has very good reproducibility and excellent correlation with Goldmann...
