Strabismus statistics

Strabismus is also called cross-eyes, lazy eye, turned eye, squint, double vision, wall eyes, floating, wandering, wayward, or drifting eyes. Associated medical terms are amblyopia, esotropia, exotropia, hypertropia, diplopia or cranial nerve palsy.

  • Strabismus affects approximately 2-4% of the population in the U.S.
  • This translates into approximately 1 in every 25 to 50 people whose eye turns to some degree at least part of the time.
  • That’s 6 to 12 million people who have lived with eyes apart in the U.S. alone.
  • A world wide estimate, based on the figures above, would be 130 to 260 million people affected by strabismus

  1. The statistics don’t address that, I think most children have surgical correction by the time they are 9, and virtually never think about the problem again, and are never bothered by it again. So, are they included in those statistics, or do those statistics only include people who are currently or would be currently diagnosed as having strabismus, that is, those who didn’t have 100% successful surgery when they were young.

  2. I was born with strabismus. I’ve had three surgeries, one when i was a month old, another one 8 months later, and another one when I was 11. I also went through the patch the better eye test when I was 4. My vision is horrible in my left eye (100/20) and my right eye is (40/20)
    I was always teased when I was younger, hated it.
    The first surgery corrected the eyes alignment to a point, but they decided they wanted to do another one 8 months later to try to make it better.
    It made it worse and up until I was 11, it was horrible. After I had the surgery when I was 11 it still wasn’t straight but it got a little better. I can’t look to my left to this day without it being noticed, and when I’m tired its noticeable also. I hate when people would look behind them to see who I’m talking to when I’m talking to them. I’ve learned to avoid looking at people and just look around. It’s become a habit, and I honestly hate it. It’d be great to at least be able to have straight eyes…but it seems that’s impossible for me.

  3. I had strabismus starting at age 2. I had a surgery around that age, and wore glasses until the 10th grade. I had my left eye patched for some time in kindergarten. The fact that I had strabismus really did not bother me until i was in 7th grade. I had stopped wearing my glasses to school because i thought i looked better without them. The less I wore them, the harder my eyes had to work. Day by day they had been getting worse, but for some reason, I payed no attention to them. I think it was because whenever I had looked in the mirror, I had been seeing the same thing, an eye that turned in, which I thought was normal for me. It’s kind of hard to explain. Anyways, I spent 7th and 8th grade very paranoid about my eyes. I began wearing glasses again in 9th grade, but was still very paranoid about my eye turning in. Eye contact was so stressful, that I barely was able to comprehend what the person was saying due to being to busy making sure that they weren’t noticing my eye. I ended up getting surgery in November of 2013, my Junior year of high school, and it was a pretty successful surgery. If anyone out there that has strabismus is reading this, know that you are certainly not alone, and that you need to not be so hard on yourself and possibly talk to your family about how you’re feeling. Surgery is an awesome option
