Acetazolamide
Glaucoma
Suitability: Low | Topical Carbonic Anhydrase Inhibitors (CAls) appear to be more effective in reducing lOP compared to systemic CAIs, have fewer side effects and are presently preferred.
Additional Therapy: Glaucoma requires urgent treatment and medical therapy. This generally includes hyperosmotic agents, e.g. mannitol 1-2g/kg over 20-30 mins as a slow IV infusion, and prostaglandins topically.
