Stye

Introduction to Stye Stye is commonly known as the pinhole, which is an acute suppurative inflammation of the sebaceous glands or meibomian glands near the eyelash follicles. There are two kinds of glands in the eyelids, called the sebaceous glands at the root of the eyelashes, which are open to the hair follicles; the other is called the meibomian glands, which are buried in the tarsal plate near the membrane surface, opening to the gingival margin, and the sty in the glands is the two glands. Acute suppurative inflammation, the bacteria causing stye is mostly Staphylococcus aureus, so the stye is mostly purulent inflammation. Because the meibomian glands in the inflamed state are surrounded by the firm tarsal tissue, the yellow pus is often faintly exposed on the surface of the congested sacral conjunctiva, and the pus may be worn through the conjunctival sac. The opening of the meibomian gland may be mild. Uplift, congestion, can also discharge pus along the parotid tube, a few also from the skin to wear pus, if the seesaw failed to wear, and the toxicity of the disease is strong, the inflammation expands, invading the entire seesaw Tissue, forming an eyelid abscess. basic knowledge The proportion of sickness: 0.2% Susceptible people: no special people Mode of infection: non-infectious Complications: eyelid eczema allergic eyelid dermatitis

Stigma etiology

Bacterial infection (28%):

The parotid gland is located deep in the eyelid, but it is open to the rim. Bacteria (mainly Staphylococcus) can enter the sebaceous glands at the base of the eyelashes or the meibomian glands in the deep eyelids to cause acute suppurative inflammation and form sty.

Resistance decreased (20%):

Healthy people's eyelids have a strong defense ability, it can resist the invasion of external bacteria, but when the body's resistance is weakened (such as malnutrition, lack of sleep or diabetes, etc.) is easy to develop.

Eye disease (15%):

When suffering from facial inflammation, trachoma, chronic conjunctivitis or excessive use of the eye and eye diseases such as myopia, hyperopia, astigmatism, etc., there is no timely correction of the lens, and the stigma can also cause stye.

Eye hygiene (28%):

Do not pay attention to eye hygiene, wipe the eyes with dirty towels, handkerchiefs, etc., bacteria invade the orbital glands, can directly cause stye.

Stye prevention

Prevention common sense

1. Always keep your eyes clean and don't wipe your eyes with unclean hands, towels, handkerchiefs, etc.

2. Patients with blepharitis, conjunctivitis or trachoma should be treated promptly.

3. If you have diabetes, multiple hair loss, tuberculosis, tonsillitis and other chronic diseases, you should treat them promptly.

4. When there are myopia, hyperopia, astigmatism, it should be corrected in time.

Stye complication Complications, eyelid, eczema, allergic eyelid dermatitis

Sometimes there will be eyelid inflammation.

Stye symptoms Common symptoms Eye redness Eyelid edema Ear lymph nodes enlarge Sintered film Congestive chills Eyelid abscess Eyelids are purple

First, the symptoms:

1, eyelid skin local redness, swelling, heat, pain, adjacent conjunctival edema.

2, 3 to 5 days after the formation of purulent sputum, the appearance of yellow pus. The external stye occurs in the sebaceous glands at the root of the eyelashes, which is manifested in the skin surface; the internal stye occurs in the meibomian glands, which is manifested in the conjunctival surface. After the ulceration and drainage, the pain is relieved, and the redness and swelling subsides.

3, the severe with the ear, submandibular lymph nodes and tenderness, body chills, fever and so on.

Second, the classification:

The hordeolum is divided into two types, internal and external.

1. Hordeolum externum is an acute suppurative inflammation of the Zeis gland (Cais gland). At the beginning of the gingival margin, there is localized congestion and swelling. After about 2 to 3 days, an induration is formed. The pain and tenderness are obvious. After the induration gradually softens, a yellow pus is formed at the root of the eyelashes, and the pus is quickly healed. If the pathogenic bacteria are highly toxic, it can cause edema in the eyelids and nearby conjunctiva. Lymph nodes are swollen before the ear, especially in the sacral area. Severe cases may have systemic symptoms such as chills and fever.

2. The hordeolum interunm is an acute suppurative inflammation of the meibomian glands. The clinical symptoms are not as strong as the external stye, because the meibomian glands in the inflammatory state are surrounded by firm tarsal tissue. On the surface of the conjunctiva that is congested, the yellow pus is often faintly exposed, and the pus may be worn through the conjunctival sac. There may be mild bulging at the opening of the meibomian gland, congestion, and drainage of pus along the parotid gland. A small number of puss are also worn from the skin. If the tarsal plate is not worn, the toxicity of the disease is strong. , the inflammation expands, invading the entire epiphyseal tissue, forming an eyelid abscess.

Stye check

The focus of the stye examination: pay attention to the changes in the eyelids, the skin of the eyelids is red, swollen, hot, and can touch the induration and tenderness. Severe cases of conjunctival surface congestion, and there are pus points, fever, accompanied by submandibular or pre-auricular lymphadenopathy. It can reach swollen lymph nodes and tenderness before the ear. If the streak patient has a systemic response, the number and classification of peripheral blood leukocytes should be examined.

Stye diagnosis and identification

diagnosis

With a small mass on the meibomian gland, the doctor has a longer course, no redness, no pain, a clear boundary, and no adhesion to the skin, so that a diagnosis can be made.

Differential diagnosis

Should pay attention to the identification of the following diseases

(1) tarsal adenocarcinoma: the mass on the tarsal plate occurs in the elderly, or recurrence in the original place after surgical curettage. The possibility of this disease should be considered.

(2) Identification of secondary infection of sputum granuloma and internal stye: The former has painless nodules or lumps, and then there are symptoms of redness and swelling, while the latter is acute, red and swollen nodules appear at the same time.
