ABSTRACT

Purpose: To describe and evaluate the epidemiological factors of patients with open globe injury in the Asociación para Evitar la Ceguera en México, and correlate the results with the ocular trauma score (OTS).
Methods: Retrospective, longitudinal and descriptive review of the records of patients with corneo-scleral ocular injury admitted to our hospital between January 1996 and December 2000. A standardized form was used for documenting the following variables: Age, gender, interval between trauma and medical attention and surgical management, mechanism and extent of ocular injury, surgical intervention, complications and final visual acuity. We included only the records that had complete information. We used multivariate and descriptive statistical analysis, using the SPSS 9.0 version.
Results: Records from 117 patients of 650 were included, with an average follow-up time of 10.9 months (range 1 to 60 months). 81.2% of the patients were male. Mean age was 26.3 years (3 to 67 years). The average length of time between trauma and attendance to a health center was 28.93 hours (1–360 hrs), and the average length of time between trauma and surgery was 48.65 hours (1-480 hrs.) Student was the most common profession (35.5%), and the object that caused of the injuries in most of the cases was glass (25%). The most affected structure was the cornea (97.4%). The most common surgery was corneoscleral injury suturing (52.4%), and zone I was the most common affected zone (73.5%). We divided the results of initial and final visual acuity in the 3 different zones, and found in all of them that low initial visual acuity related to low final visual acuity, as well as the opposite.
Conclusions: Ocular trauma epidemiology in our hospital is comparable with other countries. We found no correlation between our results and the estimated probability of follow-up visual acuity category by the OTS, therefore it had no predictive value. The extension of the trauma and the initial visual acuity were the variables most related to the final visual acuity.
