Predictive factors of blindness in patients with simple chronic glaucoma

Abstract

An analytic cases and controls study to estimate the causal load of the ocular hypertension and the central corneal thickness as predictive factors of blindness was carried out in 300 patients with simple chronic glaucoma, belonging to "Frank País García" Polyclinic in Santiago de Cuba, during the 2016. Forty cases were selected (blind patients) and 260 controls (not blind patients). The data were processed through the database system IBM SPSS Statistics 21 for Windows. For the logistical regression there was 88,3% of probability of successes in the result of the dependent variable, reason why it was assumed that it was 2,74 times more probable to develop blindness in patients who presented high intraocular pressure and 2,38 times in those with a decreased central corneal thickness than in those who didn't show these risk factors, when the other independent variables remained constant.
