High pressure in the eye, also known as ocular hypertension, is caused by an imbalance in the production and drainage of fluid in the eye. The fluid, called aqueous humor, is normally produced and drained to maintain a steady pressure inside the eye. When the drainage channels become blocked or the eye produces too much fluid, the pressure inside the eye increases, which can lead to damage to the optic nerve and vision loss
. This can be caused by various factors such as fluid buildup, eye trauma, certain medications, and other eye conditions
. For instance, an injury to the eye or a condition like pseudoexfoliation syndrome can disrupt the natural drainage system, leading to increased eye pressure
. Additionally, factors such as age, family history of glaucoma, and certain medical conditions can also contribute to ocular hypertension
