摘要

Purpose

This study aimed to evaluate the anterior segment parameters and axial length (AXL) in myopic Saudi adults, using Pentacam AXL.

Study Design

This study was a non-randomized, cross-sectional, observational, and quantitative study.

Subjects and Methods.

The study included 98 myopic eyes (from only right eyes) of 98 healthy Saudi females aged 19 to 30 years. Each subject underwent autorefraction without cycloplegia. Subjective refraction with fogging was conducted to relax accommodation. Maximum and minimum keratometry, anterior chamber depth (ACD), corneal horizontal diameter, central corneal thickness, corneal asphericity (Q), and AXL were measured using the Pentacam AXL® single rotation Scheimpflug camera.

Results

A strong correlation was observed between SE and AXL (r = 0.565, p < 0.001), indicating that longer AXL was associated with more myopic SE. Additionally, AXL showed a moderate negative correlation with a patient’s age at the onset of myopia (r = − 0.290 & p = .004). However, AXL showed no significant correlation with the patients’ age, mean keratometry, maximum keratometry, minimum keratometry, or corneal horizontal diameter, ACD, central corneal thickness, and Q.

Conclusion

This study provided valuable insights into the complex interplay between multiple variables that contribute to myopia progression. This understanding is crucial for early detection, tracking of progression, and treatment of this condition.
