Objective:

To investigate the association between myopia severity and the risk of developing open-angle glaucoma and the need for glaucoma surgery, highlighting the clinical significance of these findings.

Approach:

Key Findings:

• Myopia is associated with a 44% higher hazard of glaucoma development compared to nonmyopia (aHR 1.44).
• High myopia is linked to a 167% increased risk of glaucoma (aHR 2.67).
• Myopic individuals have a higher incidence of glaucoma surgery, with an aHR of 1.71, increasing to 3.07 for high myopia.
• Filtering surgeries show the largest relative differences in risk between myopic and nonmyopic patients (aHR 2.03 for myopia and 4.03 for high myopia).

Interpretation:

The study provides quantitative evidence of the increased risk of glaucoma and surgical intervention in myopic populations, emphasizing the need for monitoring and management in clinical practice.

Limitations:

• Glaucoma severity and progression could not be directly assessed.
• Refractive error could not be modeled continuously due to lack of granular data.
• Potential misclassification of myopia and glaucoma due to diagnostic code limitations.
• Causality cannot be established due to the retrospective observational design.

Conclusion:

This study is the first to quantitatively link myopia with glaucoma surgery needs, underscoring the critical importance of early detection and management strategies for myopic patients.
