Glaucoma primarily affects the optic nerve, which plays a crucial role in vision by transmitting visual information from the retina to the brain. The disease is characterized by damage to the optic nerve, often due to increased intraocular pressure, leading to progressive vision loss if left untreated.

Understanding that glaucoma's primary impact is on the optic nerve is essential for recognizing the importance of early detection and management of intraocular pressure. Damage to the optic nerve can result in peripheral vision loss and, in advanced stages, can lead to complete blindness.

The other structures mentioned—such as the cornea, iris, and retina—while important components of the eye, are not primarily affected by glaucoma in the same way as the optic nerve. The pathophysiology of glaucoma specifically targets the nerve fibers within the optic nerve head, making it a critical area of concern in the management and treatment of this condition.
