What is the only treatment approach for glaucoma?

• A. Lowering of IOP through medications, surgery, or laser
• B. Prescription of glasses
• C. Increasing sunlight exposure
• D. Vitamin supplementation

Answer: (A)

Glaucoma treatment is focused on lowering intraocular pressure because this pressure is the main modifiable factor that drives optic nerve damage in POAG. Lowering IOP can be achieved in three broad ways: medications (eye drops or other agents that reduce production or increase outflow of aqueous humor), laser therapy to improve drainage, or surgical procedures to create new drainage pathways. Together, these approaches reduce stress on the optic nerve and slow or prevent vision loss. Glasses don’t affect the disease process since they only correct refractive error, not the optic neuropathy. Sunlight exposure and vitamins don’t have proven effects on glaucoma progression.
