What is determined by the rate aqueous enters and exits the eye?

Epithelial cell count
Intraocular pressure
Presence of a vitreous hemorrhage
Corneal curvature

Explanation

Answer: B - Intraocular pressure

Intraocular pressure (IOP) is determined by the rate aqueous enters and exits the eye. If the aqueous is not getting taken up by the trabecular meshwork as fast as it is being produced by the ciliary body, then the IOP will increase.
