辽宁省彰武地区人眼前节形态学测量

目的 量化辽宁省彰武地区的人群眼前房深度(ACD)、前房角(CA)和前半晶状体厚度(AHLT)的变异。方法 对彰武地区290名晶状体透明、年龄分布在8～73岁的人进行初步的眼前节形态流行病学研究。在以光照诱发缩瞳的情况下，用Nidek EAS-1000拍照测量CA；在散瞳下，拍照测量ACD和AHLT。结果 随着年龄的增加，ACD变浅、AHLT变厚，而CA变窄。AHLT在男性与女性之间没有明显差异。女性的ACD比男性的浅，CA比男性的窄，在50岁组和60岁组中更为明显。结论在北方国人中，ACD和CA随着年龄的增加而下降，而女性比男性下降更多，在50岁年龄组和60岁年龄组中更为明显。
