Ocular hypertension is one of the most widespread conditions that affects the eyes. It occurs when there is a higher level of fluid pressure (intraocular pressure) in the eyes than usual. Glaucoma, and even permanent vision impairment, can occur if ocular hypertension is ignored, therefore it's important to take action against the condition. High intraocular pressure or ocular hypertension has no symptoms, so it is diagnosed during a visit to your eye care specialist. Eye drops are usually one of the first treatments used to treat high eye pressure, but unfortunately they do not work for everyone.
