Question

Timolol/Propranolol in glaucoma Name the following (Two examples for each): (5x1=5)

Q150.3 marksShort Answers

Answer

Timolol is the appropriate choice — a non-selective beta-blocker formulated as a topical eye-drop specifically for glaucoma, lowering intraocular pressure by reducing aqueous humour production at the ciliary epithelium, with minimal systemic absorption at ocular doses. Propranolol is not used topically for glaucoma and lacks an ophthalmic formulation for this purpose; systemic beta-blockade would not be the appropriate route for a local, sight-specific effect.
