A tumor is an abnormal growth of any tissue or structure; it can be either benign or malignant. Benign tumors often remain localized, while malignant tumors often spread into surrounding structures. A tumor can affect any part of the eye, such as the eye socket, eyeball, eye muscles, optic nerve, fat, and tissues. Sometimes tumors grow into the eye area, or tumors from other parts of the body travel to the eye. Most tumors of the eye are benign.
Unlike chicken pox, shingles is usually quite painful. Although this disease often occurs in normal, healthy people, it occurs more frequently in elderly or immune-compromised individuals.
A pterygium is a mass of fleshy tissue that grows over the cornea. It may remain small or may grow large enough to interfere with vision. A pterygium most commonly occurs on the inner corner of the eye, but it can appear on the outer corner as well.
Many medical conditions will cause red eye or pink eye. Red Eye essentially refers to any redness of the eye, from any condition. Causes of red eye can be infectious, inflammatory, glaucoma, dryness, trauma or other reasons.
Blepharospasm is an involuntary contraction and spasm of the eyelid muscles that causes your eyes to squeeze shut. Blepharospasm is more common in women and usually appears after the age of 50. Generally, one will notice that one's eyes are blinking and twitching more often. On occasion, it can progress to repeated, forceful, involuntary closing of the eyes.
Eyelid surgery is a common method of treatment for entropion (inward turning of the eyelid), ectropion (outward turning of the eyelid), ptosis (drooping of the eyelid), and some eyelid tumors.
Entropion is an inward turning of the eyelid and lashes toward the eye, usually caused by relaxation of the eye muscles and tissue due to aging.
Ectropion is an outward turning of the lower eyelid, most commonly caused by aging, although eyelid burns or skin disease may also be responsible.
The cornea is the clear front window of the eye. It covers the iris (the colored portion of the eye) and the round pupil. The cornea is composed of five layers. The outermost layer is called the epithelium.
Botox is the trade name for botulinum toxin. In its pure form, botulinum toxin is a poisonous neurotoxic protein that is found in certain spoiled foods and causes muscle weakness. It acts as a nerve impulse blocker, preventing muscles from contracting. In an extremely dilute form, botulinum toxin has many medical applications.
Blepharitis (Lid Margin Disease)
Lid margin disease is a common and frequently chronic inflammation of the eyelids (blepharitis). Symptoms include irritation, itching, and, occasionally, a red eye. This condition frequently occurs in people who tend to have oily skin, dandruff, or dry eyes. Bacteria normally reside on the skin, but in some people, they thrive in the skin at the base of the eyelashes. Nearby oil glands may be overactive, causing dandruff-like scales and particles to form along the lashes and eyelid margins, which can cause redness, stinging, or burning.
