视网膜脱离手术的填充材料种类繁多,主要有两大类,即生物材料及运用高分子材料。我们自1982年以来采用脱水脐带作填充材料治疗视网膜脱离53例(56眼),除6例作巩膜外填压术余47例均作巩膜间层填压术。取得满意效果,现报告如下:材料及方法取新生儿脐带,截成每段30～40mm,先用无菌生理盐水洗净,再沿脐静脉剪开并用无菌生理盐水洗净抹干,经75%的酒精浸泡消毒24小时,再用95%酒精脱水备用。植 Retinal detachment surgery fill a wide range of materials, there are two main categories, namely, biological materials and the use of polymer materials. We have used dehydrated umbilical cord as filling material to treat retinal detachment in 53 cases (56 eyes) since 1982. All the other 47 cases underwent extracapsular filling were used for interspinous filling. Achieve satisfactory results, are as follows: Materials and methods Take neonatal umbilical cord, cut into sections of 30 ~ 40mm, first with sterile saline wash, then cut along the umbilical vein and washed with sterile saline wipe dry 75% alcohol soaked for 24 hours, then 95% alcohol dehydration standby. plant
