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
