what is hte difference between strasbismus and amblyopia?

Answer 1

Amblyopia - diminish of sight esp. on one eye without change in eye structures (lazy-eye)
Strabismus - inability of one eye to attain binocular vision with the other bcoz of imbalance of the muscles of the eyeball (cross-eye)

Answer 2

They can both be there in the same set of eyes, which is what often confuses people.

Strabismus: squint, turn, cast...
The two eyes do not line up, look at the same object at the same time.

Amblyopia. The affected eye has poor vision because its connections with the brain are undeveloped.

This often happens *with* strabismus in children, where, rather than see double, the brain concentrates on one eye and the development of the squinting eye is neglected.

But there are other reasons for amblyopia, for example a big difference in Rx between the eyes, where there can be amblyopia without strabismus.

And not everyone with strabismus has amblyopia. Some people can switch, using *either* eye quite happily, just not both at once. (alternating squint)

Answer 3

Strabismus is cross-eye. Amblyopia is when one eye goes lazy and is not used to see--it can be a result of a lot of things. The two causes of amblyopia I know of are strabismus (one eye is so out of focus due to the cross-eye that the brain just starts to ignore it) and major differences in prescription in two eyes (the more hyperopic eye becomes lazy in that case).

People confuse amblyopia and strabismus so much because a lot of people don't understand that strabismus is not the only eye problem that can cause amblyopia.
