Glaucoma Diagnosis and Testing for Adults
Glaucoma is a disease that directly affects the optic nerve, which is responsible for carrying images to the brain. When this key nerve is damaged, blind spots begin to appear. If left untreated, total blindness will be the end result.
Glaucoma occurs when the drainage angle is blocked and excess aqueous fluid cannot freely flow out of the eye. This produces increased fluid pressure, which pushes against and damages the optic nerve.
Early detection is critical to ensure that you get the treatment you need right away. One of the best and easiest ways to prevent glaucoma from occurring and destroying your vision is to schedule regular check ups with your ophthalmologist.
During an exam, your ophthalmologist will assess the level of pressure in your eye as well as the angle of drainage to ensure there is not excessive pressure on the optic nerve from a buildup of fluid. Other tests include peripheral vision and possible photographs of the optic nerve.
There are two types of glaucoma, closed-angle and primary open-angle. Typical symptoms include blurred vision, headaches, nausea, rainbow-colored halos that appear around lights and severe eye pain.
While glaucoma cannot be reversed, it can be controlled. Eye drops, surgery, or other medications may be prescribed to help lower eye pressure or decrease aqueous fluid.
