We studied 50 consecutive cases of severe penetrating ocular trauma with posterior segment involvement for which vitreous surgery and scleral buckling were performed as secondary reparative procedures. Eyes with a better prognosis, such as those with anterior segment injuries alone and intraocular foreign bodies, were excluded. Of 50 eyes, 31 (62%) had a successful outcome. There was a significant difference in visual outcome between those eyes that had received blunt and sharp penetrating trauma. Visual acuity of 20/50 or better was more frequently attained in eyes with sharp penetrating trauma (P = .002). Thirty-three eyes had initial retinal detachment; 17 (52%) were successfully repaired. Blunt penetrating trauma produced retinal detachment more frequently than sharp penetrating trauma (22 of 29 vs 11 of 21). Retinal detachment was more often successfully repaired after sharp penetrating trauma (8 of 11 vs 9 of 22). Contusive damage to the choroid and retina limited final visual and anatomic results after blunt rupture of the globe.
我们研究了50例连续性严重穿透性眼外伤伴后节受累患者，对其进行玻璃体手术和巩膜扣带术作为二期修复手术。排除预后较好的眼，如仅前段损伤和眼内异物的眼。50眼中，31眼（62%）获得成功结果。钝性和锐性穿透伤眼的视觉结果有显著差异。锐性穿透伤眼更常获得20/50或更好的视力（P = .002）。33眼最初有视网膜脱离；17眼（52%）成功修复。钝性穿透伤比锐性穿透伤更易导致视网膜脱离（29眼中的22眼 vs 21眼中的11眼）。锐性穿透伤后视网膜脱离更常成功修复（11眼中的8眼 vs 22眼中的9眼）。眼球钝性破裂后脉络膜和视网膜的挫伤性损伤限制了最终的视觉和解剖学结果。
