简介：目的：比较泪道探通治疗对三个年龄组的先天性鼻泪管阻塞患者的成功率。方法：共180例先天性鼻泪管阻塞患者根据年龄分为3组,Ⅰ组（4～6mo）,Ⅱ组（7～12mo）和Ⅲ组（13～24mo）,均行泪道探通治疗。症状体征均消失为治疗成功的标准。用卡方检验分析结果。结果：Ⅰ组治疗成功率为100.0%,Ⅱ组治疗成功率为88.5%,Ⅲ组治疗成功率为82.3%,总的治愈率为90.7%。结论：泪道探通治疗的有效性随着年龄的增加降低。在6mo时行泪道探通治疗的孩子成功率最高,能完全消除症状。

简介：目的通过超声乳化白内障吸除术对不同年龄段老年患者角膜内皮的影响的观察,探讨年龄和角膜内皮功能的相关性。方法不同年龄段的年龄相关性白内障患者（排除眼部其他疾患和糖尿病全身病）78例（83眼）,分为66岁以下、66-73岁、74-84岁、85岁以上四个年龄组,给予超声乳化白内障吸除手术治疗,以非接触眼科专用角膜内皮镜,测量手术前后角膜内皮细胞的数量,对手术前后角膜内皮的减少数值进行统计分析。结果同组术前、术后角膜内皮细胞减少有统计学意义（P〈0.01）,各组间因手术影响的减少值之间差异有统计学意义（P〈0.01）。结论高龄老年患者角膜内皮对手术损伤的敏感性高,术前应对角膜内皮细胞的功能评估应结合年龄段重新评估。
