The most common type of glaucoma, Open Angle Glaucoma (OAG), occurs when there is either a sustained increase in fluid production or a decrease in fluid drainage. With this imbalance in fluid flow, there is an increase in the intraocular pressure, which in turn reduces the blood flow in the sensitive tissues of the optic nerve. Over time, as the optic nerve fibers are destroyed, peripheral (side) vision is lost.
Glaucoma has no symptoms, even while damage is being done, therefore early detection, through regular and complete eye exams, is the key to protecting your vision from damage caused by glaucoma.
OAG treatment concentrates on lowering the pressure inside the eye to prevent damage to the optic nerve. The most common treatments for glaucoma have been the use of medications in the form of eye drops or pills, as well as laser treatments. If these methods fail to decrease fluid pressure, surgery may be required to create a new drainage channel.
