Final answer:
Glaucoma is a condition resulting from an abnormally high intraocular pressure inside the eye, which can lead to optic nerve damage.
Step-by-step explanation:
The condition that results from an abnormally high pressure inside the eye is called glaucoma. This pressure, known as intraocular pressure, helps maintain the shape of the eye. When the circulation of fluid in the eye is blocked, it leads to the buildup of pressure, risking permanent damage to the optic nerve and potential vision loss. Excessive intraocular pressures can be detected through routine testing, especially important for individuals over 40 years of age when the risk for glaucoma increases.
