Study Purpose

To evaluate the relationships between axial length, body height, refractive error, and sex

Overview

Study Design

Prospective study

# of Eyes/
Patients

72 eyes of 36 myopic subjects (19 girls and 17 boys); mean age of 11.1 ± 1.42 years, (ranging from 8 to 14 years)

Study Device

Topcon MYAH biometer (Topcon, Tokyo, Japan),
Shin-Nippon NVISION-K 5001 (Rexxam Co., Kagawa, Japan)

Outcome Measures

Correlations between refractive parameters, AL, body height, and age, and between refractive parameters, AL, and age based on sex Differences in body height and ocular refraction based on AL, differences in AL and ocular refraction based on body height percentile, and differences in body height, AL, and ocular refraction based on the sex of the participants

Results

AL was negatively and moderately correlated with sphere power and SE (Spearman’s correlation, r ≤ −0.571, both p < 0.001). No significant correlations were found with other refractive components (Spearman’s correlation, all p ≥ 0.208) (Table 1)
AL was also positively and weakly correlated with body height (Spearman’s correlation, r = 0.283, p = 0.016) (Table 1)
Age was strongly correlated with body height (Spearman’s correlation, r = 0.839, p < 0.001) but not with refractive parameters or AL (Spearman’s correlation, all p ≥ 0.223) (Table 1)
There were no significant correlations between AL and age in either the female or male participants (Spearman’s correlation, both p ≥ 0.223)

Conclusions

• In summary, there is a relationship between the AL of the eye and its refractive status • In addition, individual anatomical characteristics such as body height and sex also play a role in these parameters. It was observed that AL and myopic refractive error are higher in the taller and male subjects
