Medications for Angle Closure Glaucoma

Introduction to Angle Closure Glaucoma Management

The American Academy of Ophthalmology recommends the primary medications used to treat angle closure glaucoma include topical beta-adrenergic antagonists, alpha2-adrenergic agonists, carbonic anhydrase inhibitors, parasympathomimetics, and oral or intravenous hyperosmotic agents 1, 2

In acute angle closure, the American Academy of Ophthalmology suggests first-line medical therapy includes topical beta-adrenergic antagonists, topical alpha2-adrenergic agonists, carbonic anhydrase inhibitors, and topical parasympathomimetics to lower intraocular pressure (IOP) before definitive treatment with laser iridotomy 1, 3
The American Academy of Ophthalmology recommends hyperosmotic agents for rapid IOP reduction in severe cases of acute angle closure glaucoma 1, 3

The American Academy of Ophthalmology suggests that after laser iridotomy, ongoing IOP management follows similar principles to open-angle glaucoma, including the use of topical medications such as prostaglandin analogs, beta-adrenergic antagonists, alpha2-adrenergic agonists, and topical carbonic anhydrase inhibitors 1, 2, 5

The American Academy of Ophthalmology notes that mydriatics may be more effective than miotics in cases of secondary pupillary block due to intraocular gas, oil, vitreous, or lens-related pupillary block 1, 2
The American Academy of Ophthalmology recommends setting a target IOP approximately 20% lower than baseline measurements 4

The American Academy of Ophthalmology suggests that definitive treatment typically requires laser iridotomy, with a favorable risk-benefit ratio 1, 3
The American Academy of Ophthalmology notes that lens extraction has growing evidence to support its use for substantial IOP lowering in some patients 1, 3
