What causes vision disturbances in glaucoma patients?

In glaucoma patients, vision disturbances primarily result from damage to the optic nerve, which occurs due to various factors associated with the disease. Glaucoma is often characterized by increased intraocular pressure, which can lead to the compression of the optic nerve fibers, resulting in their degeneration. This degeneration affects the transmission of visual signals from the retina to the brain, ultimately causing vision disturbances.

The optic nerve is critically responsible for relaying visual information, and when it sustains damage, patients may experience symptoms such as peripheral vision loss, blurred vision, or even blindness in advanced stages. Early intervention to manage intraocular pressure can help protect the optic nerve and preserve vision, highlighting the importance of understanding and monitoring this condition for effective treatment.
