方法：将就诊的82例球结膜下出血患者随机分成两组，和血明目片组(50例50眼)：口服和血明目片5片，每日3次； 维生素C组(32例32眼)：口服维生素C 0.2g每日3次，并进行临床观察。

结果：随访1mo，和血明目片组治愈40例，7例有效，3例无效，总有效(治愈+有效)率为94%； 维生素C组治愈16例，9例有效，7例无效，总有效(治愈+有效)率78%。两组有效率差异有统计学意义(P=0.015<0.05)。

结论：和血明目片治疗球结膜下出血疗效显著，可明显缩短病程，方法简单，未发现不良反应，安全可靠，疗效确切，值得在临床治疗中应用推广。

METHODS: Eighty-two(82 eyes)patients randomly received either Hexuemingmu tablets treatment(n=50 cases)or Vitamin C treatment(n=32 cases). Patients were treated with Hexuemingmu tablets(5 tablets)or Vitamin C(0.2g)by oral drugs(3 times a day)respectively. They were clinical observed.

RESULTS: After 1 month,among 50 patients treated with Hexuemingmu tablets, 40 patients were cured, 7 patients were improved and 3 patients were invalid. The total effective rate was 94%(47/50). While in Vitamin C group, 32 patients were treated, 16 patients were cured, 9 patients were improved, and 7 patients were invalid. The total effective rate was 78%(25/32). There was a significant statistical difference between the two groups(P=0.015<0.05).
