What condition is characterized by high pressure in the eye?

Glaucoma is the condition characterized by high pressure in the eye, also known as intraocular pressure (IOP). This elevated pressure can damage the optic nerve over time, leading to vision loss and potentially blindness if not treated. The increase in intraocular pressure often occurs when the eye does not drain fluid effectively, causing a buildup. There are various types of glaucoma, with open-angle glaucoma being the most common.

Understanding glaucoma is crucial because it often develops gradually and may not present symptoms until significant damage has occurred. Regular eye exams can help in early detection and management of the condition, which can include medications, laser treatment, or surgery to lower the eye pressure.

In contrast, cataracts involve clouding of the eye's lens, which affects vision but is not directly related to eye pressure. Retinal detachment is a serious condition where the retina separates from the back of the eye, and while it can be associated with various causes, it is not characterized specifically by high eye pressure. Macular degeneration pertains to the deterioration of the central portion of the retina and affects central vision but does not relate to intraocular pressure either.
