Glaucoma is a condition that specifically involves increased fluid pressure within the eye, known as intraocular pressure (IOP). This elevated pressure can damage the optic nerve, which is crucial for vision. The increase in fluid pressure is typically caused by a buildup of aqueous humor, either due to an obstruction in the drainage canals or an imbalance in the production and absorption of this fluid.

In glaucoma, the associated damage to the optic nerve can lead to vision loss if not managed effectively. Regular eye examinations are important for detecting changes in eye pressure, especially since many individuals may not experience noticeable symptoms until significant damage has occurred. Treatment options for glaucoma often include medications to reduce intraocular pressure, laser therapy, or surgical procedures to improve drainage.

The other conditions mentioned, while they may affect eye health, do not involve the characteristic feature of increased intraocular pressure that defines glaucoma. For example, cataracts involve clouding of the lens, retinal detachment pertains to the separation of the retina from its underlying supportive tissue, and conjunctivitis is an inflammation of the conjunctiva, often caused by infections or allergens. Each of these conditions has its own distinct pathophysiological mechanisms and implications for vision.
