What condition is indicated by increased intraocular pressure?

Increased intraocular pressure is primarily associated with glaucoma, a condition that affects the optic nerve and can lead to vision loss if not treated. Glaucoma occurs when the fluid in the eye (aqueous humor) does not drain properly, causing pressure to build up. This pressure can damage the optic nerve, which is essential for transmitting visual information from the eye to the brain.

Monitoring and managing intraocular pressure is crucial in diagnosing and treating glaucoma. It can be asymptomatic initially, but as the disease progresses, it may lead to noticeable visual field loss and eventually blindness. This connection makes glaucoma the correct answer as it directly relates to the condition of increased intraocular pressure, distinguishing it from other options which do not specifically indicate this increase.
