Ocular hypertension Latanoprost

The term ocular hypertension usually refers to any situation in which the pressure inside the eye, called intraocular pressure, is higher than normal. Eye pressure is measured in millimeters of mercury (mm Hg). Normal eye pressure ranges from 10-21 mm Hg. Ocular hypertension is an eye pressure greater than 21 mm Hg with no changes in vision or damages to the structure of the eyes. Elevated IOP is the most important risk factor for glaucoma, so those with ocular hypertension are frequently considered to have a greater chance of developing the condition.

Open-Angle Glaucoma Latanoprost
Glaucoma is a condition resulting in optic nerve damage and vision loss in patients. Open-Angle Glaucoma is the most common form of glaucoma. The front part of the eye is filled with a clear fluid called the aqueous humor. This fluid is constantly made in the back of the eye. It leaves the eye through channels in the anterior chamber angle of the eye, to drain into the bloodstream.
In Open Angle Glaucoma, the channels in the angle narrow with time, making it hard for the fluid to drain properly increasing pressure in the eye. This higher pressure pushes on the junction of the optic nerve and the retina at the back of the eye, reducing the blood supply to the optic nerve. Glaucoma is a leading cause of blindness in elderly patients.
