Pharmacology MCQs- 227 #usmle

A 45-year-old woman is sent to the emergency room from a vision center after examining her eyes to get new glasses. While she was in the waiting room, she developed severe ocular pain in her right eye and she started seeing halos around light.

Which of these agents most likely is the reason for this patient’s condition?

A- Acetazolamide

B- Atropine

C- Neomycin

D- Pilocarpine

E- Timolol


Primary closed angle glaucoma is a medical emergency. It occurs quickly due to sudden increase of intraocular pressure. Acute attack may be precipitated by dilation of the pupil after application of atropine eye drops as in this patient. Neomycin is an antibiotic and has no role in glaucoma. Other agents are used in the treatment of glaucoma.

The correct answer is B
