Ячмень и его осложнения: причины, лечение и профилактика

the swelling of an eyelid

Stye complications occur in very rare cases. However, the most frequent complication of styes is progression to a chalazion that causes cosmetic deformity, corneal irritation, and often requires surgical removal. Complications may also arise from the improper surgical lancing, and mainly consist of disruption of lash growth, lid deformity or lid fistula. Large styes may interfere with one's vision. Eyelid cellulitis is another potential complication of eye styes, which is a generalized infection of the eyelid. Progression of a stye to a systemic infection (spreading throughout the body) is extremely rare, and only a few instances of such spread have been recorded.

A stye is caused by a bacterial infection. The bacteria are Staphylococcus aureus in about 95% of cases. The infection leads to the blocking of an oil gland at the base of the eyelash. Styes are experienced by people of all ages. Styes can be triggered by poor nutrition, sleep deprivation, lack of hygiene, lack of water, and rubbing of the eyes. Styes can be secondary to blepharitis or a deficiency in immunoglobulin.

Stye prevention is closely related to proper hygiene. Proper hand washing can reduce the risks of developing not only styes, but also many other types of infections. Upon awakening, application of a warm washcloth to the eyelids for one to two minutes may be beneficial in decreasing the occurrence of styes by liquefying the contents of the oil glands of the eyelid and thereby preventing blockage. To prevent styes, cosmetics and cosmetic eye tools should not be shared among people. Like with all infections, regular hand washing is essential, and the eyes should not be rubbed or touched with unclean hands. Contaminated eye makeup should be discarded and sharing of washcloths or face towels should be curtailed, to avoid spreading the infection between individuals. Breaking the stye may spread bacteria contained in the pus and should be avoided.

Most cases of styes resolve on their own within one to two weeks, without professional care. People with styes should avoid eye makeup (e. g., eyeliner), lotions, and wearing contact lenses, since these can aggravate and spread the infection (sometimes to the cornea). People are advised not to lance the stye themselves, as serious infection can occur. Other antibiotics, such as chloramphenicol or amoxicillin may also be used. Chloramphenicol is used successfully in many parts of the world, but contains a black box warning in the United States due to concerns about aplastic anemia, which on rare occasions can be fatal. Antibiotics are normally given to people with multiple styes or with styes that do not seem to heal, and to people who have blepharitis or rosacea.

Incision and drainage is performed if resolution does not begin in the next 48 hours after warm compresses are started. Medical professionals will sometimes lance a particularly persistent or irritating stye with a needle to accelerate its draining. Surgery is the last resort in stye treatment. Styes that do not respond to any type of therapies are usually surgically removed. Stye surgery is performed by an ophthalmologist, and generally under local anesthesia. The procedure consists of making a small incision on the inner or outer surface of the eyelid, depending if the stye is pointing externally or not. After the incision is made, the pus is drained out of the gland, and very small sutures are used to close the lesion. Sometimes the removed stye is sent for a histopathological examination to investigate possibility of skin cancer.

A 2017 Cochrane review found low certainty evidence that acupuncture helps in hordeolum compared with antibiotics or warm compresses. There was also low certainty evidence that acupuncture plus usual treatment may increase the chance of hordeolum getting better, though they could not rule out placebo or observer effect, since the studies reviewed either had no positive control, were not blinded, or both.

The word stye (first recorded in the 17th century) is probably a back formation from styany (first recorded in the 15th century), which in turn comes from styan plus eye, the former of which in turn comes from the old English stīġend, meaning "riser", from the verb stīgan, "to rise". The older form styan is still used in Ulster Scots today. The homonym sty found in the combination pigsty has a slightly different origin, namely it comes from the Old English stiġ fearh—fearh (farrow) is the Old English word for "piglet"—where stiġ meant "hall" (cf. steward), possibly an early Old Norse loanword, which could be cognate with the word stīgan above. The synonymous late Latin expression is hordeolum, a modulation of the word hordeolus, which is related to hordeum ("barley"), after its resemblance to a barleycorn. In Czech, a sty is called ječné zrno (from ječmen "barley" and zrno "seed or grain"); in German, it is called Gerstenkorn (barleycorn). In Hebrew it is called שעורה Seh oh Ráh ("barley"). In Polish it is called jęczmień ("barley"). In Hungarian it is called árpa ("barley").
