To evaluate the gender-related differences in demographic and ocular biometric trends in a defined population presenting for consultation within the Italian public health system and to collect data of several ocular parameters at different stages of life, highlighting the differences between females and males.
In this retrospective study, keratometry, corneal astigmatism, and axial eye length of 729 patients (729 eyes; mean age: 58±21 years; range: 18-96 years) were evaluated using partial coherence interferometry. Statistical evaluation was performed utilizing a paired -test and R analysis.
In females (396 eyes of 396 patients), mean keratometry ranged between 40.59-47.78 D (44.27±1.36 D), corneal astigmatism ranged between 0-3.82 D (1.13±0.74 D), and axial length ranged between 20.5-31.32 mm (24.07±1.74 mm). In males (333 eyes of 333 patients), mean keratometry ranged between 38.5-46.95 D (43.54±1.35 D; p<0.001), corneal astigmatism ranged between 0.1-3.97 D (1.15±0.79; p=0.75), and axial length ranged between 20.41-31.21 mm (24.57±1.78 mm; p<0.001). Both genders presented a shorter axial length in advanced age. Elderly males presented a higher percentage of against-the-rule astigmatism.
Females may have steeper corneas and shorter eyes. A trend toward axial length reduction with age was observed in both genders. This finding is probably due to the difference in growth between generations, as the new ones have an higher size than the old ones.
评估在意大利公共卫生系统中前来咨询的特定人群的人口统计学和眼部生物特征趋势中的性别差异，并收集不同生命阶段的多个眼部参数数据，突出女性和男性之间的差异。
在这项回顾性研究中，使用部分相干干涉测量法评估了729例患者（729只眼；平均年龄：58±21岁；范围：18 - 96岁）的角膜曲率、角膜散光和眼轴长度。采用配对t检验和R分析进行统计学评估。
女性（396例患者的396只眼）中，平均角膜曲率在40.59 - 47.78 D之间（44.27±1.36 D），角膜散光在0 - 3.82 D之间（1.13±0.74 D），眼轴长度在20.5 - 31.32 mm之间（24.07±1.7 mm）。男性（333例患者的333只眼）中，平均角膜曲率在38.5 - 46.95 D之间（43.54±1.35 D；p<0.001），角膜散光在0.1 - 3.97 D之间（1.15±0.79；p = 0.75），眼轴长度在20.41 - 31.21 mm之间（24.57±1.78 mm；p<0.001）。两个性别在高龄时眼轴长度均较短。老年男性逆规散光的比例更高。
女性可能有更陡峭的角膜和较短的眼轴。两个性别均观察到眼轴长度随年龄减少的趋势。这一发现可能是由于代际间生长差异所致，因为新一代的体型比老一代更大。
