摘要目的 回顾性总结严重机械性眼外伤后视力无光感眼的伤情、相应的手术治疗方式及其手术治疗后效果,分析对手术后视力结果和眼球最终结局的影响因素.方法 对42例42只眼严重眼外伤所致的无光感眼施行玻璃体视网膜联合手术,观察其疗效.术后随访6～36个月,平均15个月.结果 42例外伤后无光感眼中,15例术后恢复了光感或光感以上的视力,27例仍无光感,其中2例行眼球摘除.严重眼外伤无光感眼视功能丧失主要原因为致密浓厚玻璃体积血、视网膜脱离及视网膜、脉络膜严重广泛的损伤、缺损.而术前伤情、玻璃体手术时机等均会影响手术的成功和视力预后.结论 严重眼外伤后无光感并不意味着视力永久性的丧失,正确的早期修复和适时、恰当的玻璃体视网膜手术,可获得一定的视力,视力无法恢复者可暂时维持眼球外观.

abstractsObjective To evaluate the efficacy of vitreoretinal surgery in the treatment of traumatized eyes with no light perception. Methods Vitreoretinal surgery on 42 eyes of traumatized eyes with no light perception of 42 patients was performed. The patients after the operations were followed up for 6-36 months (averaged 15 months). Results Postoperatively; 15 of 42 patients had visual acuities of LP to 0.1, 27 eyes remained NLP in which 2 had enucleation. The traumatic condition; the opportunity of vitreoretinal surgery were the most important factors influencing the prognosis of postoperative VA in severe mechanical injuried eye.Conclusions The dense vitreous hemorrhage, the damaged or detached retina and the choroid edema are the main causes of NLP. Therefore; NLP does not always mean permanent loss of vision. Some patients of NLP may get some visual acuities after proper primary repair of the wound and timely vitreoretinal surgery. The eyes with NLP can maintain eyeball- shape.
