眼钝挫伤致眼底损伤的玻璃体手术治疗

目的评价玻璃体手术对眼钝挫伤引起的眼底损伤的疗效。方法对1992年10月～1998年3月连续收治的、经玻璃体手术治疗的眼球钝挫伤101例(105只眼)作回顾性研究。结果按伤情分为4组：玻璃体积血23只眼，玻璃体积血伴视网膜脉络膜破裂或视神经损伤25只眼，外伤性视网膜脱离46只眼以及视网膜巨大裂孔11只眼。手术后77只眼(73.3%)视力改善，其中0.02～0.6者占65.7%(38只眼在0.1～0.6，占55.0%)，2只无光感眼恢复 了0.1以上视力，26只眼(24.8%)视力不变；2只眼(1.9%)视力下降。视网膜复位54只眼， 占视网膜脱离及视网膜巨大裂孔者的94.7%。结论严重眼球钝挫伤可造成多种眼底损害和视力丧失，适时的玻璃体手术可挽救大多数伤眼。(中华眼底病杂志,1999,15:100-102)

Vitreous surgery for treatment of fundus damages caused by ocular blunt trauma

Purpose To evaluate the efficacy of vitreous surgery for treatment of fundus damages caused by ocular blunt trauma. Methods Clinical records were reviewed retrospectively for a series of consecutive 101 patients (105 eyes)with fundus damages caused by ocular blunt trauma underwent vitreous surgery from October 1992 to March 1998. Results Based on clinical examination and findings during surgery,all cases were divided into 4 subgroups:vitreous hemorrhage(VH)in 23 yes,VH with retinochoroidal rupture or optic damage in 25 eyes,traumatic retinal detachment in 46 eyes,and retinal giant tear in 11 eyes.Vision acuityimprovementachieved in 77 eyes(73.3%)and of them 69 eyes(65.7%)had 0.020.6with 38 eyes(55.0%)better than 0.1.Two eyes with no light perception obtained better than 0.1. Visual acuity remained unAuthor changed in 26 eyes(24.8%)and 2 eyes(1.9%)became worse after operation.The retina reattached in 54 eyes(94.7%). Conclusion Severe ocular blunt trauma may cause visual impairment and various fundus damages.Appropriate vitreous surgery can salvage most eyes with those injuries.
