One of the most important concepts in modern myopia management is axial length.
Axial length refers to the measurement of the eye from the front (cornea) to the back (retina).
Why Axial Length Matters
When myopia develops, the eye typically becomes longer. This increased length causes light to focus in front of the retina, leading to blurry distance vision.
As the eye continues to grow, myopia usually becomes stronger.
Tracking Eye Growth
By measuring axial length regularly, eye care professionals can track how quickly the eye is growing.
This provides valuable information about:
• how myopia is progressing
• whether treatment is working
• whether adjustments may be needed
A More Precise Way to Monitor Myopia
Simply checking glasses prescriptions does not always provide the full picture of how myopia is changing.
Axial length monitoring allows us to directly measure eye growth, making it a powerful tool in myopia management.
At Northern Optics, axial length monitoring helps guide treatment decisions and provides a more precise approach to managing myopia.
