The age trends of refractive errors, astigmatism and optical components were studied in 220 Chinese subjects aged over 40 years. Myopia did not dominate in this age group. With increasing age, the prevalence of hyperopia increases from 2% at age 40-45 years to 66% at age > 65 years. Against-the-rule astigmatism was more prevalent than the other types. Significant correlations were found between age and spherical equivalent power, age and vitreous depth and axial length. Sex differences were found among the optical components but not in the refractive error. Myopia appears to be more prevalent among the younger age groups than the older age groups of the Hong Kong Chinese population, and the importance of genetics in determination of refractive error is called into question by these findings.
对220名年龄超过40岁的中国受试者的屈光不正、散光和眼屈光成分的年龄趋势进行了研究。在这个年龄组中近视并不占主导。随着年龄的增长，远视患病率从40-45岁时的2%增加到65岁以上时的66%。逆规散光比其他类型更常见。年龄与球镜等效度、年龄与玻璃体深度及眼轴长度之间存在显著相关性。在眼屈光成分中发现了性别差异，但在屈光不正方面未发现性别差异。在香港华人人群中，近视在较年轻年龄组中似乎比在较年长年龄组中更普遍，这些研究结果对遗传学在屈光不正决定中的重要性提出了质疑。
