Sties
Definition
Also known as an external hordeolum, a stye is an infection or small abscess formation within the hair follicle glands on the free edge of the eyelid. These sebaceous glands are also known as Zeis's or Moll's glands.
Description
A stye may develop on or under the eyelid with an eyelash within a yellow point. The area becomes red, warm, swollen, and painful. It may also cause blepharitis, an inflammation of the eyelid.
Causes & symptoms
A stye is caused by staphylococcal or other bacterial infection of the sebaceous gland. This infection may be only on the eyelid, or may also be present elsewhere in the body. The presence of a stye may be a sign of the need for glasses, or indicate declining overall health status.
In addition to localized redness, pain and swelling, the affected eye may be sensitive to bright light. The individual with a stye may complain of a gritty sensation in the affected eye, and notice that the eye has increased tearing. Once the abscess drains, localized pain and other symptoms quickly resolve.
Diagnosis
Individuals can usually identify a stye from its accompanying symptoms. A laboratory culture of the drainage from the stye may be done to determine the causative organism, allowing identification of the appropriate topical antibiotic drop, ointment or cream, if necessary, to prevent bacterial infection of the rest of the eye.
Treatment
Application of a warm-water compress for 15–20 minutes several times daily will help bring the stye to a point. Most sties drain spontaneously, or with gentle removal of the affected eyelash. The affected individual should avoid hand-to-eye contact, and wash hands frequently, drying thoroughly with clean towels.
A somewhat unusual local treatment that was recommended by a pediatric ophthalmologist for sties that will not drain after several days of warm-water compresses is the application of a hot potato. The hot potato holds heat longer than a washcloth.
Because a stye may also be the result of overall poor health, intake of a well-balanced diet and other measures to strengthen the immune system are helpful in healing and preventing recurrences. Foods rich in beta carotene, along with vitamin C and A are beneficial in early stages of bacterial infection; herbal remedies include garlic, echinacea, goldenseal, calendula, and tea tree oil. Focus on a healthy lifestyle will also include getting enough rest, exercising regularly, and limiting negative stress. Yoga, meditation, and guided imagery may be helpful for stress reduction and relaxation. Eye irritation from smoking or other chemical or environmental factors should be avoided.
