You probably know that myopia — nearsightedness — causes faraway objects to appear blurry, but have you heard of ‘high myopia,’ the most severe form of nearsightedness? Knowing what myopia is and how to slow or halt its progression before it accelerates can lower your child’s risk of developing sight-threatening eye diseases later in life.
At Pupila Family Eye Care in Houston we offer myopia management to help preserve your child’s vision.
What Is High Myopia?
Myopia is caused by an excessively curved cornea, which is the clear, outer part of the eye. An abnormally curved cornea bends light entering the eye, causing the light to focus in front of the retina instead of directly on it. This results in blurry distance vision.
High myopia is like regular myopia except that the cornea’s curvature is more dramatic, and the cause is often hereditary. High myopia is having a refractive error of -6.00 or higher, but even children with myopia as low as -3.00 or higher are at greater risk of serious eye conditions in adulthood.
In contrast, regular myopia can arise from both genetic and environmental factors.
Will Myopia Always Get Worse?
Myopia often progresses in childhood, and even more so when there's a family history of nearsightedness. Given the risks associated with myopia, it’s important to schedule regular eye exams for children with myopia to detect any worsening of the condition.
Regular myopia tends to progress, especially between the ages of 7 and 18, when most kids and teens experience growth spurts. The eye grows as the body grows, so the irregular curvature of the cornea becomes more pronounced.
In 50% of all myopia cases, progression stops at around 15 years of age. However, with high myopia, the condition continues to progress until around the age of 24, and sometimes later.
High Myopia and Its Risks
High myopia can dramatically raise a child’s risk of developing the following eye conditions in adulthood:
- Cataracts - cloudy formations on the eye (4.5x increased risk)
- Glaucoma - optic nerve damage caused by increased pressure inside the eye (3x increased risk)
- Retinal detachment - displacement of the retina from its support tissue (12x increased risk)
- Myopic macular degeneration - damage to the macula, the central part of the retina (845x increased risk)
- Pathological myopia - worsening of high myopia to the point of vision loss
All of these eye conditions can cause vision loss and may require eye surgery. Therefore, it’s essential to monitor your child’s myopia with regular comprehensive eye exams and to learn the various ways we can manage your child’s myopia.
How Myopia Management Can Help
While myopia is worrisome, there is good news: an optometrist-designed program of myopia management can slow the progression of myopia by up to 78%, and can often halt it.
The sooner a child starts a myopia management program, the better. Treating a child’s myopia in its early stages is the best way to ensure that it won’t progress to high myopia.
If you’re interested in myopia management for your child, contact us at Pupila Family Eye Care in Houston and schedule a comprehensive eye exam. We will determine which type of myopia management program is right for your child based on the severity of their myopia, age and other factors.

Frequently Asked Questions with Dr. Supriya Krishnan
Q: At what age can my child start myopia management?
A: Growth spurts can aggravate the elongation of the cornea. Therefore, myopia management can be very effective for children as young as 7-8 years old.
Q: Will Myopia Cause Blindness?
A: Myopia itself doesn’t cause blindness, but it greatly increases the risk of developing eye diseases that can cause vision loss. Myopia management, which can slow myopia progression, can reduce the risk of these sight-robbing conditions and can guard your child’s vision for the future.
