Concordancia entre la tonometría de Goldmann, Icare Pro y Corvis ST

Abstract

Purpose To compare intraocular pressure (IOP) between the new non-contact tonometer Corvis ST (CST), the Goldmann applanation tonometry (GAT) and Icare Pro rebound tonometer (PRO). Methods A total of 178 eyes of 178 healthy subjects were selected for the study. Measurements of IOP were made in a random order with GAT, PRO and CST. Central corneal thickness (CCT) was determined by ultrasound pachymetry. The mean of three valid measurements of each variable was used in the statistical analysis. The relationship between the tonometers was established using Bland-Altman plots. Conclusions The differences found between PRO and GAT were significantly higher than those found between CST and GAT, which showed non-significant differences. The measurements of the three tonometers were affected by the CCT. La incidencia de sangrado clínicamente significativo ha disminuido drásticamente desde 1980. Los factores de riesgo más importantes son el fallo respiratorio y las coagulopatías. Los inhibidores de la bomba de protones (IBP) o los antagonistas de receptores H2 (H2RA) se utilizan en la profilaxis de sangrado por úlceras de estrés. Ambos medicamentos han mostrado ser superiores al placebo en la reducción del riesgo de sangrado gastrointestinal, y los IBP son por lo menos tan efectivos como los H2RA. Se ha mostrado que la alimentación enteral temprana reduce el riesgo de sangrado por úlceras de estrés, aunque solo en estudios retrospectivos.
