Glaucoma is best described as what?

• A. Increased tear production
• B. Blockage of tears drainage
• C. Impaired outflow of aqueous humor
• D. Inflammation of the sclera

Answer: (C)

Glaucoma is defined by impaired outflow of aqueous humor, which raises intraocular pressure and damages the optic nerve over time. The eye continuously produces aqueous humor in the ciliary body, and it normally drains through the trabecular meshwork into Schlemm’s canal. When drainage is reduced or blocked, pressure builds up and injures retinal ganglion cells, leading to vision loss. This focus on drainage and pressure distinguishes glaucoma from tear-related issues or scleral inflammation. Increased tear production, blocked tear drainage, or scleral inflammation describe other eye problems, not glaucoma.
