What does a miotic agent do in the eye?
A) Increase intraocular pressure
B) Constrict the pupil
C) Dilate the pupil
D) Reduce the vitreous humor
B) Miotics constrict the pupil to allow the aqueous humor (not vitreous humor) flow out of the eye

The contraindications include adhesions between the iris and the lens as well as ocular infections also.
What does a beta adrenergic blocker do when given in the eye?
A) Lowers blood pressure
B) Stops production of vitreous humor
C) Increases intraocular pressure
D) Constricts the pupil
D) Beta blockers constrict the pupil and reduce the production of aqueous humor. It is not supposed to reduce blood pressure, but if the drops are administered incorrectly and they get into the lacrimal duct and can cause low BP.

Timoptic and betagan are beta blocker miotics.
Which medication is given as an emergency treatment for closed angle glaucoma?
A) Lasix
B) Mannitol
C) Timoptic
D) Diamox
B) Mannitol (Osmitrol) is very effective, but is only given in case of emergency.
