Ophthalmology · Glaucoma: malignant glaucoma
Sample itemAfter trabeculectomy for angle closure, a patient develops a very shallow central and peripheral chamber with high IOP despite a patent iridotomy. Which drug is useful?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
D. Atropine
Malignant or ciliary block glaucoma is due to aqueous misdirection into the vitreous. Cycloplegics such as atropine tighten the zonules and pull the lens back, and miotics worsen the condition.
Option by option
A. Brimonidine alone
Brimonidine alone does not treat the mechanism.
B. Pilocarpine
Miotics aggravate ciliary block.
C. Latanoprost
Prostaglandin analogues do not reverse the block.
D. Atropine (correct)
Correct. Cycloplegia tightens the zonule and deepens the chamber.
