摘要: 本文报告5例钝挫伤致脉络膜破裂病例。病变大多位于眼底后极部,沿视盘周围分布,可单独存在,亦可多发。其形态多为弧形;亦有蟹爪形、蝶形等。眼底荧光血管造影早期,病变即透见荧光;中期显强荧光,边界清晰,显影均匀,直至造影后期亦很少出现染料渗漏。如不合并严重黄斑部病变,大多数这类患者可保持有用的黄斑功能。晚期如发生视网膜脱离或出血性浆液性视网膜病变、则视力预后不佳。应用复方樟柳碱治疗本病有效。Abstract: Five Cases of indirect choroidal tears following blunt nonperforating injury to the eyes are reported.
