Glaucoma causes damage to the optic nerve through increased?

Glaucoma causes damage to the optic nerve primarily through increased intraocular pressure (IOP), which can result from an imbalance in the production and drainage of aqueous humor in the eye. This elevated pressure can compress the optic nerve fibers, leading to vision loss. Over time, if left untreated, the damage can become irreversible, emphasizing the importance of early detection and management. Regular eye exams are crucial for monitoring eye health and preventing significant vision impairment.
