An internal hordeolum (stye) is an infection of the meibomian gland. The meimbomian glands exist in both the upper and lower eye lids and normally secrete oils over the front of the eyes, as part of the normal tear film. The internal hordeolum occurs more frequently in the upper lids. These are red, swollen and painful to the touch. The onset and duration of an internal hordeolum is usually more prolonged as compared to an external hordeolum.
Because the infected tissue is deep within the eyelid, the use of topical antibiotics is ineffective in treatment. In most mild cases of hordeolum (stye), the use of hot compresses is sufficient to cause the gland to drain. Many people who are bothered by recurring styes have reported that frequent application of hot compresses actually reduces the instances of infection.
Special self-heating, non toxic heat packs that can be used over and over are a great treatment for this condition. They are available from Dr. Allan J. Panzer at the Houston Dry Eye Clinic, 4760 Beechnut St., Houston, TX, 77096 -- Phone: (713) 222-2020 or visit HoustonDryEyeClinic.com
