目的 :分析导致过氟化碳液体 (简称重水 )残留的常见原因及可能出现的并发症 ,探讨不同程度及条件下的重水残留应采取的最佳处理方法。方法 :5例患者在玻璃体切除术后均出现了不同程度的重水残留。 1例有晶体眼 ,少量重水残留 ,未作处理 ;1例无晶体眼残留的少量重水 ,坐位前房穿刺取出 ;1例大量重水残留角膜清亮者 ,术后短期内再次重水 /硅油交换 ,取出重水 ;1例大量重水残留角膜混浊者 ,三周后 ,局麻下采取头低坐位 ,6点角膜缘前房穿刺 ,颞下灌注口注硅油取出 ;1例术中角膜混浊 ,重水残留 ,同样采取头低坐位取出全部重水。结果 :4例患者残留之重水均成功取出 ,5例患者术后随访 3个月以上 ,视网膜复位良好 ,视力均在 0 .0 2以上。结论 :不同程度和条件下的重水残留 ,只要处理方法得当 ,术后仍可得到满意的效果。 OBJECTIVE: To analyze the common causes and possible complications that lead to the residue of perfluorocarbon liquid (referred to as heavy water), and to explore the best treatment method for the heavy water residue under different degrees and conditions. Methods: Five patients had different degrees of residual heavy water after vitrectomy. One case had a crystalline eye, a small amount of heavy water residue, untreated; a case of a small amount of residual water without crystal eyes, sitting anterior chamber puncture removed; a large residual heavy corneal clear water after heavy water / silicone oil exchange again, remove Heavy water; 1 case of heavy water residual corneal opacity, three weeks later, under local anesthesia to take the head low sitting, 6:00 limbal anterior chamber puncture, infratemporal perfusion port silicone oil removed; 1 case intraoperative corneal opacity, heavy water residue, the same Take the low head to take out all the heavy water. Results: All four patients with residual heavy water were successfully removed. Five patients were followed up for more than 3 months. The retinal reattachment was good with visual acuity of more than 0.002. Conclusion: The residual water under different degrees and conditions, as long as the treatment method properly, after surgery can still be satisfied with the results.
