[Modification of the presentation of ocular trauma by age group in an urban Mexican population].
BACKGROUND
We identified whether ocular trauma presentation, according to the system for classifying mechanical injuries of the eye, had modifications among different age groups, which could be useful as damage predictors during the initial evaluation of these patients.


METHODS
Ocular trauma referrals between 1995 and 2003 were re-qualified according to the system for classifying mechanical injuries. Patients were divided into 5-year groups and the most frequent categories of type, grade, pupil and zone were determined by group. Mean age of each category and the rate of categories between groups were compared (ANOVA and Kruskal-Wallis, chi2 and odds ratio [OR]).


RESULTS
Five hundred sixty-six eyes of 551 patients were evaluated (age: 0.5-90 years, mean age: 27.7); mean age was lower for type B closed globe trauma and zone II (p < 0.05). There was a higher rate of grade 1 in patients > 60 years (OR 3.8), of grade 4 in patients < 54 years (OR 3.25) and of type B closed globe in patients > 20 years (OR 3.3). The remaining comparisons showed no clinical differences.


CONCLUSIONS
There were no significant modifications in the presentation of most of the categories between age groups. Age difference was not useful as a predictor for detecting traumatic ocular damage.
