Question

Drug used in acute congestive glaucoma are:

• A. Atropine
• B. Pilocarpine
• C. Acetazolamide
• D. Both B & C

Hint:

Lower IOP by reducing aqueous and constricting the pupil - avoid any mydriatic.

Answer 1

The Correct Option is D

Step 1: Picture a closed drainage angle. In an acute attack the peripheral iris jams against the trabecular meshwork, aqueous cannot escape, and IOP shoots up. The drugs we pick must either make less fluid or unblock the angle.
Step 2: Acetazolamide works on the supply side. By inhibiting carbonic anhydrase in the ciliary body it cuts aqueous formation, so pressure falls even while the angle is still tight.
Step 3: Pilocarpine works on the mechanics. As a cholinergic miotic it constricts the pupil, dragging the iris root out of the angle and reopening the meshwork for outflow.
Step 4: Atropine does the opposite - it dilates and bunches the iris into the angle, a known trigger, so it is contraindicated. Since both pilocarpine and acetazolamide are correct, the combined option wins.
\[\boxed{\text{Both Pilocarpine and Acetazolamide}}\]
