STY (Hordelum) :
sty is tendered ,painful red bumps located at at the base of eyelash or under or inside the eyelids.The medical term used for sty is hordelum.
A sty results in an acute infection of th oil gland of the eyelid(meibomain gland) that occurs after these glands have been clogged.A sty may also arise from an infected hair follicle at the base of an eyelash. The bacterium staphylococcus aureus is responsible for 90-95% cases of sty.
Staph aureus is frequently found on skins.A sty can develop as a complication of blepharitis(inflammation of the eyelids)
A sty is sometime confused with a chalazion which is a type of cyst and arise due to chronic inflammation in the meibomain gland and is painless as compared to sty.
SIGN SYMPTOMS AND PROGNOSIS OF STY :
The first symptom of sty is generally redness,tenderness and pain in the affected area.The eye may feel irritated or "scratchy".Later symptoms can include swelling, discomfort due to blinking of eye and sensitivity to light.A common sign of a sty is a small,yellowish spot at the center of the bumps that develops as pus expands in the area.
People with certain chronic condition (like diabetes mellitus, chronic blepharitis, seborrhea and some chronic debilitating illness ) are more prone to develop sty as compared to normal one.
In many susceptible case stress seems to trigger the development of sty.
Studies has shown that persons who have high level of blood lipids are more susceptible to blockage in the oil gland including those of eyelids and therefore are more likely to develop sty.
A sty is harmless in majority of cases.In most of cases sty ruptures on its own within a few week leading to relief from the symptom.But still some people have to go under some surgical treatment.
Progression of systematic infection is extremely rare but still we should remain careful as some instances has been recorded.
