Eye Disorders

Diseases of the eye can cause visual disability ranging from minor impairments to total blindness. Some forms of visual disability can be prevented through prompt attention and others may be cured. Unfortunately, there are other eye conditions that cannot be prevented or treated. Research is aimed at improved prevention, diagnosis and treatment of visual disorders. Through research, a great deal of knowledge has already been gained about the eye and the diseases that threaten its normal function.

Cataract (kat'ah-rakt)
One of the leading causes of blindness in the country, cataract is a clouding of the lens which obstructs the passage of light to the retina. Almost all cataracts can be successfully removed by surgery with resulting restoration of useful vision. There are four main types of cataract: senile, which is the most common form and is associated with aging; congenital, which occurs at birth; secondary, which follows another eye disease; and traumatic, which follows an injury.

Corneal Disease (kor'ne-al)
Diseases of the cornea may scar this transparent tissue causing disability. Causes of corneal blindness include injuries, infections and age related diseases. Corneal diseases can frequently be successfully treated by drugs or surgery. In some cases, corneal transplants can restore vision to people who have suffered severe corneal scarring.

Diabetic retinopathy (ret'I-nop'ah-thee)
Disorder of the blood vessels in the retina stemming from diabetes. It is one of the leading causes of blindness in this country. The disease is sometimes treated with laser or other forms of light energy.

Glaucoma (glaw-ko'mah)
Increased pressure in the eye causing damage to the optic nerve and impaired vision. Glaucoma is another leading cause of blindness. If detected early, the most common form of the disease usually can be controlled with medication. In other cases, surgery may be necessary.

Macular Degeneration (mak'u-lar)
Irreversible and progressive damage to the macula portion of the retina resulting in a gradual loss of fine or reading vision. It is a leading cause of blindness in this country and is usually associated with aging.

Retinal Detachment (ret'n-el)
Separation of the inner sensory layer of the retina from the outer pigment epithelium, leading to loss of retinal function. Usually caused by a hole or break in the inner sensory layer that permits fluid from the vitreous to leak under the retina and lift off the innermost layer of the retina. If detected early and treated promptly with surgery, retinal detachment can often be repaired and vision restored.
