Blinding choroidal rupture in a karateka.

Abstract

A case of uniocular visual loss secondary to trauma study in Scotland' showed that over 25 % of contestants sustained during a competitive karate bout is reported.in a karate competition sustained some type of injury (Br J Sports Med 1995; 29: 273-274) and 41 % of these injuries were to the head and neck. (Figures 2 and 3). At the time of discharge he had a disciform scar at the left fovea and an acuity of 3/60 with no possibility of improvement. DiscussionTo the best of our knowledge, this is the first blinding eye injury reported in a karateka. However, rather than view this as an interesting but isolated case, we feel this incident should remind all involved in the martial arts of the risks involved. There are numerous published reports detailing both the frequency and severity of injuries sustained." One American study of the Tae Kwon Do national championships, found that 52% of all injuries involved the head and neck region.2 During the first European knockdown karate championships 53% of the competitors were injured and 30 % of these injuries were to the head and neck.3 These previous reports suggest that under tournament conditions the distinction between those martial arts disciplines that permit full contact and those that do not becomes blurred. This is consistent with previous work that has found that injuries tend to be more severe under tournament conditions than when training.4 There have been several recommendations aimed at reducing both the rate and the severity of injury.

“…Ein Teil davon betreibt Karate als Wettkampfsport. In Einzelfallstudien ist von schweren und auch tödlichen Verletzungen im Karate berichtet worden [2,4,6,8,10,11]. In einem Vergleich mit einer Reihe populärer Sportarten wurden im Karate die meisten Verletzungen registriert [5].…”

Youth Participation and Injury Risk in Martial Arts

“…Other reported karate injuries to adolescents and adults include a blinding choroidal rupture, 22 a unilateral adrenal gland hematoma, 23 a femoral osteochondral fracture, 24 and a traumatic pseudoaneurysm of the femoral artery. 25 …”

Choroidal Rupture

“…5 Virtually any form of traumatic injury to the eye can result in choroidal ruptures. Sports injuries predominate in the literature, including injuries occurring during karate, 6 or caused by various sports equipment including a hockey puck, 7 soccer ball, 8 cricket ball, 9 basketball, 9 tennis ball, 10,11 golf ball, 12 baseball, 13 or paint ball.
