目的 描述外伤性玻璃体前脱离所致的基底部撕裂与视网膜巨大裂离的临床特征 ,评价玻璃体切割术对其疗效。方法 回顾性研究 7例由钝性所致玻璃体基底部撕裂和视网膜裂离 (范围 12 0～ 15 0°)患者 ,PVRB～C3 级 ,近期视网膜脱离 5眼 ,远期 2眼。常见伴随病变晶状体半脱位、瞳孔散大、玻璃体积血。所有患者经历巩膜环扎、玻璃体切割、眼内激光和充填手术。结果 视网膜撕裂以颞侧多见 ,裂离缘多在玻璃体基底部后界 ,子午向撕裂少见。所有患者视网膜复位成功 ,术后常见并发症是暂时性高眼压。结论 玻璃体基底部撕裂可致近期或远期视网膜巨大裂离 ,玻璃体手术疗效肯定
OBJECTIVE: To describe the clinical features of basilar tear and retinal detachment due to anterior detachment of traumatic vitreous and to evaluate the efficacy of vitrectomy. Methods A retrospective study was conducted in 7 patients with blunt retinal detachment (range 12 0-15 0 °), PVRB-C3 grade, recent retinal detachment in 5 eyes, and long-term retinal detachment in 2 eyes. Common with lesion lens subluxation, mydriasis, vitreous hemorrhage. All patients underwent scleral cerclage, vitrectomy, intraocular laser and filling surgery. The results of retinal tear more common in the temporal, fissure margin more in the basal part of the posterior sector, meridian tear rare. Retinal reattachment was successful in all patients. The common postoperative complications were transient intraocular hypertension. Conclusion Tear of the basal body of the vitreous body can cause great or immediate retinal detachment, and the effect of vitrectomy is definite
