What is the term for the inability to coordinate the muscles controlling eye movement?

Strabismus

Explanation

Strabismus is the inability to coordinate eye movement muscles.

What term describes the unequal curvature of the cornea or lens, leading to distorted vision?

Astigmatism

Explanation

Astigmatism is the unequal curvature of the cornea or lens.

Which eye structure is responsible for producing aqueous humor, which maintains intraocular pressure?

Ciliary body
