ABSTRACT

Purpose. To identify the distribut ion of the injuries that cause unfavorable visual prognostic in the patients with closed globe trauma, and to determine the proportion that might be identified from the initial evaluation. Methods. Observational, retrospective, transverse and opened study in patients with closed globe trauma of a general hospital (1995 2009); eyes were excluded by diseases or previous surgeries that decreased the visual function. There was identified the distribution of the injuries that cause unfavorable visual prognostic (retinal detachment, traumatic optic neuropathy) and there decided the proportion that might be identified from the initial evaluation. Stadistics. There was compared the frequency of retinal detachment and of traumatic optic neuropathy, through of confidence intervals of 95 % for proportions. Results. 521 eyes with closed globe trauma; 151 had VD < 20/40 (29%), positive pupil in 9 (5 .9%), 150 had zone III involvement (28.8%). The injuries of unfavorable visual prognostic appeared in 10 eyes (0.19% of theseries, 6.7% of theeyeswith zone III involvement (I.C.95 % 2.21 9.79); 9 cases corresponded to traumatic optic neuropathy and one to retinal detachment. These injuries increased 10 times the frequency of the functional category of worse visual prognostic in eyes w ith zone III involvement (p = 0.003). Conclusions. Up to 1.9 % of the eyes with closed globe trauma can present injuries that cause un favorable visual prognostic, but in 90% of the cases these can be detected by accessible maneuvers from the first level of attention.
