ABSTRACT

Traumatic pupil injury may be associated to retinal injury; its functional alteration signals optic nerve damage. Prevalence of pupil alterations in traumatized eyes and its association to open-globe and retinal injury (zone III) were identified. Method: ocular trauma patients in whom the pupil could be evaluated were included; patients with superficial foreign body and uveal prolapse were excluded. The proportion of pupil alterations was determined; patients without pupil alterations were assigned to group 1, those with alterations to group 2. The proportion of open globe, grade ‹ 2, ‹ 3, 5 and zone III injury in closed globe were compared with c2 and Odds Ratio (OR) was calculated. Results: 394 patients were evaluated (age 1-90 years, av. 26.5 SD ± 15.0); 49 had pupil alterations (12%, 95% CI 9.1-15.6): 10 afferent pupillary defect, 30 iris sphincter injury, 15 corectopia and 2 polycoria. Group 2 had a higher proportion (p ‹ 0.001) of open globe (36.7 vs 8.2%, OR 9.4), grade ‹ 2 (61.2 vs 26.1% OR 6.9), grade 5 (14.3 vs 1.6% OR 14.2) and zone III in closed-globe (61.3 vs 20.6 OR 6.1). Discussion: Pupil evaluation, besides detecting optic nerve injury, may help to identify open globe and visual loss indirectly. Adding the rest of the standardized classification of ocular trauma evaluation might systematize and make initial evaluation easier, previously to the specialist’s.
