JF British Journal of Sports Medicine JO Br J Sports Med FD BMJ Publishing Group Ltd and British Association of Sport and Exercise Medicine SP 272 OP 275 DO 10.1136/bjsm.28.4.272 VO 28 IS 4 A1 Jones, N P YR 1994 UL http://bjsm.bmj.com/content/28/4/272.abstract AB One-third of orbital blowout fractures are sustained during sport. Soccer is most commonly involved. Though visual acuity recovery is usually complete, permanent loss of binocular visual field is almost universal. Typically high-energy blows by opponent's finger, fist, elbow, knee or boot are responsible. Injuries to the eye itself may also be sustained and should be looked for. Ocular protection may be feasible in some sports, but the main preventive measure to be addressed is the reduction in aggressive play or deliberate injury.
