There is nothing definite that will prevent a person from developing glaucoma, but you can slow it down with early treatment. Therefore, it is very important that you have regular eye exams. Your doctor will perform a series of painless tests -- eye pressure measurements, dilated eye exams, and sometimes visual field testing -- to check for any changes in your eye or in your vision. With early detection, glaucoma can often be controlled with medications, either eye drops or pills. If your glaucoma...
Amblyopia: A condition that starts in childhood in which vision has not developed properly in one eye or the other. If amblyopia is left untreated, a child's vision will not develop correctly, and as the brain matures, one eye will remain with poor vision.
Aqueous humor: The clear, watery fluid between the lens and the cornea.
Astigmatism: A condition in which blurred vision is caused by the cornea being shaped more like a football than spherical. Astigmatism may be compensated for through eyeglasses or contacts, or it can be corrected through refractive surgery.
Beta-blocker: A medication used in the treatment of glaucoma, beta-blocker eye drops help reduce the pressure within the eye by reducing the production of aqueous humor.
Carbonic anhydrase inhibitor: A type of medication used to treat glaucoma. Carbonic anhydrase inhibitors work by reducing the production of aqueous humor, thereby reducing pressure inside the eye.
Choroid: The layer of blood vessels between the retina and the sclera.
Choroiditis: A form of uveitis that causes an inflammation of the layer beneath the retina. It may also be caused by an infection such as tuberculosis.
Conjunctiva: A thin layer of tissue that lines the inside of the eyelids as well as the outer surfaces of the sclera.
Cornea: The clear outer layer of the eye. It covers the iris.
Cryotherapy: A surgical procedure in which abnormal cells are destroyed by freezing them.
Cyclitis: A form of uveitis that causes inflammation of the middle portion of the eye and may affect the muscle that focuses the lens. Cyclitis may develop suddenly and last several months.
Enucleation: A procedure in which the eye is removed.
Hyperopia: A condition in which a person has difficulty seeing objects up close, but objects further away are seen clearly. Hyperopia is commonly referred to as farsightedness.
Intraocular: Of or related to the inside of the eye.
Iris: The colored membrane of the eye, surrounding the pupil. The iris controls the amount of light entering the pupil by expanding and contracting.
Iritis: The most common form of uveitis, it affects the iris and is often associated with autoimmune disorders such as arthritis. Iritis may develop suddenly and may last up to eight weeks, even with treatment.
Legal blindness: Having visual acuity that, in both eyes, can not be corrected to better than 20/200 or has a visual field of 20 degrees or less (tunnel vision) remaining.
