摘要
目的评价玻璃体手术治疗外伤性复发性视网膜脱离的效果,分析其复发的原因。方法对56例(56眼)外伤性复发性视网膜脱离再次玻璃体手术的效果进行回顾性分析。对性别、年龄、眼外伤类型、术前有无眼内异物、有无硅油、手术距受伤的时间、两次手术的间隔时间、二次填充物的种类、术后眼压等进行Logistic回归分析。并总结外伤性视网膜脱离再修复的原因。结果再次手术原因:≥18岁组主要为增生性玻璃体视网膜病变(PVR);<18岁组主要为玻璃体残留和不完全玻璃体后脱离。56例视网膜复位率89.29%,以上各因素对复位率的影响差异无统计学意义(P>0.1)。56例中视力提高者50例(89.29%),影响术后视力的主要因素是两次手术的间隔时间(P=0.05)。结论外伤性复发性视网膜脱离的主要原因在成人主要为PVR,在青少年主要为玻璃体残留和不完全玻璃体后脱离,把握再修复手术时机可获得较好的效果。
Objective To evaluate the effect of vitreous surgery in cases of recurrent traumatic retinal detachment and analyze the causes. Methods 56 cases of recurrent traumatic retinal detachment underwent second vitreous surgery were studied retrospectively. Retinal reattachment and postoperative visual acuity were included as evaluation index. Logistic regression was made including gender, age, traumatic type, foreign body, silicone oil, duration between trauma and 1^st surgery, duration between 1^st and 2^nd surgery, type of second tamponade material, postoperative intraectdar pressure,et al.Tbe causes of recurrent traumatic retinal detachment were summarized.Results The causes of recurrent traumatie retinal detachment in over 18 yeats group was PVR,while in under 18 years group were residue of vitreous and incomplete PVD. The ratio of retinal reattachment was 89.3 % in 56 cases. All the factors mentioned above had no significant effects as to retinal reattachment（ P 〉 0. 1 ）. Improvements of visual acuity were noticed in 50 cases（89.3% ）. Duration between two surgeries had significant effects to postoperative visual acuity （p = 0.05）. Conclusion The cause of recurrent traumatic retinal detachment in adults is PVR, while in adolescents are residue of vitreous and incomplete PVD. A timely second vitreous surgery may have better effect.
