Indirect choroidal ruptures result from blunt ocular trauma and have a pathognomonic fundal appearance. We analysed a group of 30 patients with indirect choroidal ruptures with specific reference to the circumstances of the injury, the pattern of ocular damage, the cause of any visual loss, and the final visual outcome. Using this analysis we deduce a pathogenetic explanation for the characteristic fundus signs in patients with indirect choroidal ruptures. The majority of cases were young males injured during sport or by an assault, a minority were injured at work. Diffuse nonfocal impact injuries due to punches were associated with ruptures concentric with and adjacent to the optic disc. Focal impact injuries, due to projectiles, showed more extensive ocular damage. Seventeen of 30 patients regained 6/12 vision after injury. Injuries due to projectiles and temporally situated ruptures were associated with a poorer visual outcome than others. Macular damage was the commonest cause of visual loss, principally due to pigmentary maculopathy, traumatic inner retinal damage, and choroidal neovascular membranes rather than direct focal damage by the rupture.
间接性脉络膜破裂由钝性眼外伤引起，具有特征性的眼底表现。我们分析了一组30例间接性脉络膜破裂患者，特别关注损伤情况、眼损伤模式、任何视力丧失的原因以及最终视力结果。通过该分析，我们推断出间接性脉络膜破裂患者特征性眼底体征的发病机制解释。大多数病例为年轻男性，在运动中或受到袭击时受伤，少数在工作中受伤。拳击导致的弥漫性非局灶性撞击伤与视盘同心且相邻的破裂相关。投射物导致的局灶性撞击伤显示出更广泛的眼损伤。30例患者中有17例受伤后视力恢复到6/12。投射物导致的损伤和颞侧破裂与比其他情况更差的视力结果相关。黄斑损伤是视力丧失最常见的原因，主要是由于色素性黄斑病变、外伤性视网膜内层损伤和脉络膜新生血管膜，而非破裂的直接局灶性损伤。
