ABSTRACT

Conmotio retinae, the most common traumatic retinopathy, affects 8.6% of eyes with type A closed-globe trauma. It can be associated to other injuries and be.Lima GV y col. Conmoción retiniana mistaken for retinal detachment. Aim: To identify whether variables grade and pupil of the standardized ocular trauma classification may allow for detection of conmotio retinae in patients with and without associated eye injuries. Method: Trauma consultations with a diagnosis of conmotio retinae were selected and quali-fied by using the standardized classification. Two groups were formed: 1: isolated conmotio retinae and 2: conmotio retinae with other injuries. The rate of patients with grade 1, 2, 3, 4, 5 and positive pupil was determined. Differences between groups were analyzed with c 2 . Results: Sixty-three eyes were included with an age rank of 5 to 55 years (average 24.38). Trauma type was A in 55 eyes (87.3%) and D in 8 (12.7%). Grade was 1 in 27 eyes, 2 in 24, 3 in 5, 4 in 5 and 5 in 2. Pupil was positive in 3 eyes (4.8%). Eleven eyes were assigned to group 1 (17.5%) and 52 to group 2 (82.5%). There was no difference between grade rate or pupil be-tween both groups. Discussion: Grade and pupil by themselves could not allow for identification of eyes with conmotio retinae: 42.9% of them had a visual acuity of 20/40 or better. Ocular fundus examination must be performed in every patient with ocular trauma.
