简介：目的探讨玻璃体的手术对复杂无晶状体眼视网膜脱离(AphakicRetinalDetachment,ARD)和人工晶状体眼视网膜脱离(PseudophakicRetinalDetachment,PPRD)(PVRC级以上)的治疗效果.方法回顾性分析78例87眼ARD和PPRD,所有病人均行玻璃体切割联合眼内填充物治疗.结果首次手术视网膜复位率为78.16%,最终视网膜复位率90.8%.视力下降11眼(12.7%),不变15眼(17.2%),提高59眼(70.1%).结论彻底的玻璃体切除加视网膜切开、视网膜前膜剥除,适当应用环扎玻璃体填充物可使复杂PPRD,ARD达到较高的视网膜复位率.但ARD、PPRD一旦发生则病情进展迅速,治疗棘手,视力预后差,应从白内障手术开始加强预防.
