Blepharitis
Introduction
Introduction to blepharitis Blepharitis is a subacute, chronic inflammation of the skin of the rim, the hair follicles of the eyelashes and their glands. The gingival margin is rich in glandular tissue and fatty secretions, and is easily contaminated by dirt and germs. Clinically divided into three types: scaly, ulcerative, ankle blepharitis. The scaly person is caused by eczema and dermatitis, which is caused by excessive secretion of the gland. The ulcer is caused by the infection of staphylococcal skin and the skin of the rim. basic knowledge The proportion of illness: 0.005% Susceptible people: no special people Mode of infection: non-infectious Complications: conjunctivitis
Cause
Cause of blepharitis
Physical stimulation (30%):
Various physical and chemical stimuli (wind, dust, smoke, heat, etc.), reduced systemic resistance, malnutrition, lack of sleep, refractive error, and visual fatigue, combined with eye health, are the causative factors.
A. bisporus infection (25%):
Angular blepharitis is a Morax-Axenfeld infection caused by double-eye lesions, which is limited to the ankle and is most common in the ankle. Often associated with poor health or anemia, tuberculosis, etc. or due to lack of riboflavin.
Staphylococcus aureus infection (15%):
Ulcerative blepharitis is an acute or suppurative inflammation of the eyelash hair follicles, Zeis and Moll glands, often caused by S. aureus infection.
Prevention
Blepharitis prevention
Avoid all irritating factors, correct refractive error, pay attention to nutrition, exercise the body, treat other chronic diseases of the whole body, in order to improve the body quality.
Complication
Blepharitis complications Complications conjunctivitis
Conjunctivitis, baldness, and phlegm thickening.
Symptom
Common symptoms of blepharospasm Common symptoms There are obvious eyelids... Swollen eyelids, edema, morning, upper and lower eyelids, adhesions, sputum, neoplasms, eyelids, multiple eyelids, multiple eyelid abscesses
1. There is a burning sensation in the eyelids, which may be itchy and stinging.
2. scaly sputum redness, scaly or suede visible at the root of eyelashes; easy to remove eyelashes, can regenerate; ulcerative hemorrhagic ulcers and pustules, long-term eyelash hypertrophy, baldness or eyelashes; The skin of the ankle is impregnated or eroded, often with conjunctival conjunctivitis.
Examine
Check of blepharitis
Eyelid examination, eye examination.
The sacral margin is congested, and the epithelial scales are attached to the surface of the eyelashes and the rim. The surface of the rim can have a bit of sebum overflowing, and the sebum collects at the root end of the lashes to form a yellow waxy secretion. After drying, the scaly and suede are removed, and the congestion is revealed. The surface of the gingival margin, but without ulcers and pus, the eyelashes are easy to fall off and can resurrect. If the inflammation does not heal for a long time, it can cause the fat in the posterior lip hypertrophy to be obtuse, but not in close contact with the eyeball. If accompanied by conjunctivitis, there may be swelling and tearing of the tears and tearing. The sputum eczema is caused by tears, forcing the patient to shed tears and squatting, and the tears are intensified.
Diagnosis
Diagnosis and diagnosis of blepharitis
diagnosis
1. The skin of the rim is flushed with scaly or suede, erosion, pustules, etc.
2. Long-term conjunctivitis, baldness, and phlegm fat.
Differential diagnosis
Different from other eye inflammation. Such as conjunctivitis. Conjunctivitis is a general term for the inflammatory reaction of conjunctival tissue in the external and internal factors. Although conjunctivitis itself does not have a serious effect on vision, it can cause vision damage when its inflammation affects the cornea or causes complications.
