Visual results in zone 1 open globe ocular trauma

Abstract

Objective: Determine the factors related to final best visual acuity results in patients with zone 1 open globe ocular trauma admitted to Ramón Pando Ferrer Cuban Institute of Ophthalmology from June 2016 to June 2017. Methods: An observational prospective longitudinal descriptive study was conducted of a sample of 35 patients. The variables analyzed were age, sex, occupation, affected eye, place of the accident, causative agent, location, wound size and shape, time of evolution, production mechanism, best initial and final visual acuity, associated ocular alterations, medical treatment indicated and complications, all of which were processed into a database with the software SPSS version 21.0 for Windows. Results: Most patients were classed as categories 3 and 4 on the ocular trauma scale. Visual acuity improvement was observed in more than half of the patients three months after the trauma. The greater the initial visual acuity and the higher the ocular trauma score, the greater was the final visual acuity. The latter was directly proportional to initial visual acuity and the presence of iris hernia and hemovitreous. Conclusions: Despite the progress achieved in the classification and treatment of zone 1 open globe ocular trauma, visual loss or reduction persists in a considerable number of patients, pointing to the need of enhancing the measures aimed at preventing ocular trauma.
