Blepharitis disease classification

Blepharitis

Blepharitis medications According to the place of occurrence, blepharitis can be divided into anterior blepharitis and posterior blepharitis. Anterior blepharitis may be caused by a germ infection or an inflammatory reaction of the meibomian gland lipid leak. The most common cause of eyelid inflammation is Staphylococcus aureus. The patient's symptoms include burning sensation, irritation, itchy eyes, foreign body sensation, and hard palate with secretions on the edge of the eyelids. These symptoms are most severe when waking up in the morning, and gradually relieve the symptoms during the day, which may be similar to sleeping at night. The secretion accumulates on the edge of the eyelids and then dries out to form a hard palate. Clinical examination shows that there are hard and brittle fiber dander around the eyelashes and tangled hard palate. When the hard palate is removed, there is a slight ulcer on the edge of the eyelid. Congestion and varying degrees of microvascular dilatation and abnormal eyelashes can also be seen on the edge of the eyelid, such as whitening of the eyelashes, falling eyelashes, and inverted eyelashes. Seborrheic blebitis mainly occurs in the front eyelid. Clinically, there is an increase in secretion of the meibomian glands that causes foamy tears. The patient's symptoms include red eyes, burning sensation, and occasional foreign body sensations. , Eyelashes, eyebrows and scalp have greasy hard palate of varying degrees. Seborrheic eyelid inflammation can occur alone or in combination with bacterial eyelid inflammation or palpebral gland disability, and is often accompanied by lees skin problems.

Blepharitis after Blepharitis

Posterior blepharitis is mainly caused by the disability of the eyelid and blepharoplasty glands. It is caused by long-term irritation of the eyes, which results in progressive keratinization of the eyelid blepharoplasty glands, which reduces the oil layer secreted to the eye surface and increases the chance of eyelid inflammation. Symptoms of clinical patients include red eyes, burning sensation, foreign body sensation, and hazy vision. Examination reveals that the eyelid lid gland is tight or even blocked, and the meibomian gland is displaced backwards due to inflammation and scarring. Sometimes it is also associated with fat leakage in the front of the eyelid. Sexual inflammation. These patients often have unstable tear layers and are prone to dry eye symptoms. Patients with palpebral gland insufficiency of the eyelid are the same as those with seborrhea, often accompanied by lees skin. In addition, chemicals can also cause blepharitis. When a female patient comes to see for blepharitis, sometimes a thick layer of mascara, eye shadow and other cosmetic ingredients are found at the edge of the eyelid or even the eyelid lid gland opening.

Blepharitis medications

High Risk Group of Blepharitis

The eyelid is one of the organs that secrete sebaceous glands. The secretory glands of the eyelids secrete fat to the surface of the tear fluid. Its purpose is to reduce the evaporation of tears, but excessive secretion often causes eyelid inflammation. On hot summer days, sweat and body excretion increase sharply. Therefore, those who lack personal eye hygiene, do not pay attention to diet conditioning, and often eat foods such as frying and frying, must pay special attention to the occurrence of eyelid inflammation. Because the early symptoms of blepharitis are similar to those of all ophthalmic diseases, it is easy to be ignored. There are many patients in the outpatient clinic because blepharitis is not properly treated. It is not only often aggravated by the symptoms of eyelid inflammation, but it is also allowed to continue to worsen. Causes chronic eyelid conjunctivitis, leading to a decline in the quality of life. In severe cases, a stye (the redness and swelling of the oil glands, commonly known as needles and eyes) or swollen glands (the swelling of the oil and fat glands without redness), or even cellulitis , And therefore need to be hospitalized for systemic antibiotics. In addition, the symptoms of blepharitis are easily misdiagnosed as dry eye at the time of diagnosis, which delays the treatment time. Therefore, it is necessary to use a slit lamp to observe the changes in the eyelids to establish the diagnosis.

Blepharitis Treatment

Basic principles of eyelid

Blepharitis is stye. At the beginning of blepharitis, the eyelid swelling and pain can be applied with ice and anti-inflammatory eye drops, and antibiotics are taken orally if necessary. Most cases resolve within three to four days; if the glands are swollen and purulent, surgical dissection is required to drain the pus.

1. Eyelid cleaner to clean crusts and dandruff in the eyelash area.

2. For severe cases, especially those related to bacterial infections, antibiotic oils may be prescribed on the surface.

3. Adrenal cortex hormone oil tincture will provide short-term relief. For stubborn cases, oral antibiotics may be needed. If the infection has spread to the cornea, antibiotics and corticosteroid drops may be needed to treat the infection.

Eyelid external treatment

(1) When the pus is not brewed in the early stage, use hot and humid compresses to help dissipate.

(2) Use Zijin tablets or Qinghuo Pills, adjust external eye drops or other anti-inflammatory eye drops or cold boiled water, and apply the skin to the affected area; you can also apply Ruyi golden cream to local skin. Caution: Do not apply the drug to the eyes.

(3) Take a few segments of fresh duckweed, remove the leaves and stems, wash and bake on the flame of an alcohol lamp or fire, squeeze with your fingers, and quickly apply the medicine flowing from the broken end to the affected area. Apply to the eyes 4 to 5 times a day.

(4) Use fresh 1-2 odors of red, white flowering Hedyotis, dandelion, wild chrysanthemum, etc., wash and smash, apply the skin of the affected area externally, be careful not to apply it to the eyes.

Eyelid surgery

When it has become pus, it should be cut open and drained. When the pus head is on the skin surface of the eyelid, the incision should be parallel to the eyelid string; when the pus head is on the inner face of the eyelid, the incision should be perpendicular to the eyelid string. Attention must be paid: if the affected area becomes pus, do not squeeze it. If the symptoms such as swollen eyelids, purple swelling, severe pain, or headache accompanied by aversion to cold are severe, but the condition worsens, treat the eye Dan.

Eyelid test

I. Diagnosis:

Usually, a regular examination of the eyelids and eyelashes can make a diagnosis.

Second, the differential diagnosis:

Blepharitis is similar to the symptoms of squamous cell carcinoma at the early stage of onset. It is not difficult to distinguish the two by culture or biopsy.

Blephar complications

The common complications of this disease are: keratitis, vision loss, conjunctivitis and so on.

Eyelids precautions

1. When the eyelid is red and swollen with pus, do not squeeze it by hand. Because the eyelid is rich in blood vessels, the veins of the eye communicate with the intraorbital and facial veins, and the intracranial cavernous sinus, and the veins of the eye lack a static valve. When the abscess is squeezed, the blood flows back to all sides, causing inflammation to spread and cause Serious comorbidities, such as orbital cellulitis, cavernous sinus embolism, and sepsis, are life-threatening and should be addressed.

2. Go to the hospital in time to ask an ophthalmologist for treatment. If you have had pus, you can perform incision and drainage, which can promote early recovery and reduce scars.
