Eye Conditions
Glaucoma
Glaucoma is a form of optic neuropathy (disease of the optic nerve). The optic nerve is made up of many nerve fibers (like an electric cable with its numerous wires), and transmits images to the brain. In glaucoma, nerve fibers are damaged, which can result in vision loss.
Most cases of glaucoma are associated with an elevated pressure inside the eye, known as intraocular pressure (IOP). When the aqueous humor (a clear liquid that normally flows in and out of the eye) cannot drain properly, pressure builds up. The resulting increase in IOP can damage the nerve fibers.

Dry Eye
Your eyes constantly produce tears at a slow and steady rate so that they stay moist and comfortable. Some people are not able to produce enough tears or the appropriate quality of tears to keep their eyes healthy or comfortable. This condition is known as dry eye. Symptoms of dry eye include scratchiness, stinging, stringy mucus in or around the eyes, and blurry vision.
Sometimes people with dry eye experience excess tearing. This is the eye’s response to the discomfort from dry eye. When the eyes get irritated, the gland that makes tears (lacrymal gland) releases a larger than usual volume of tears, which overwhelm the tear drainage system. These excess tears then overflow from your eyes. More Information on Dry Eye
Floaters and Flashes
Small specks or clouds moving in your field of vision as you look at a blank wall or a clear blue sky are known as floaters. Most people have some floaters normally but do not notice them until they become numerous or more prominent. More Information on Floaters and Flashes
First Aid for Eye Injuries
The most common type of eye injury that needs immediate action is a chemical burn. Alkaline materials, such as lye, plaster, cement, and ammonia, can cause severe damage and even blindness. Solvents, acids, and detergents also can be very harmful to the eye. Eyes should be flushed liberally with water if exposed to any of these agents. More Information First Aid for Eye Injuries
