Introduction
Introduction to ocular herpes zoster Ocular herpes zoster is a more serious sputum skin disease caused by the infection of the varicella-zoster virus by the semilunar ganglion or a branch of the trigeminal nerve. Patients who are receiving radiation therapy or immunosuppressive therapy are prone to this disease. Lifetime immunization after onset, rarely recurrence. The direct pathogenic factor is the infection of herpes zoster virus. The virus enters the human body through the nasal mucosa. It invades the detection of the nervous system. It can enter the cortex along the tetrahedral nerve and also propagate in the nerve mapping. The most direct cause of the disease is the infection of herpes zoster virus. The virus enters the human body through the nasal mucosa. It invades the detection of the nervous system. It can enter the cortex along the tetrahedral nerve and also propagate in the nerve mapping. Chickenpox occurs when a child with low immunity is infected. Some patients become infected with the virus without symptoms, and then lurk, and will be active when the body's resistance declines. basic knowledge The proportion of sickness: 0.01% Susceptible people: no special people Mode of infection: non-infectious Complications: keratitis iritis
Cause
Eye herpes zoster
Virus infection (30%):
The direct pathogenic factor is the infection of herpes zoster virus. The virus enters the human body through the nasal mucosa. It invades the detection of the nervous system. It can enter the cortex along the tetrahedral nerve and also propagate in the nerve mapping. Chickenpox occurs when a child with low immunity is infected. Some patients become infected with the virus without symptoms, and then lurk, and will be active when the body's resistance declines.
Trauma factors (30%):
When the body is traumatized, devastated drugs or other touching, the ambush virus starts to move, causing hemorrhagic inflammation of the posterior root nodule, and descending neuritis to make the nerve separation area The skin is dew blistering, and its patient has low defiance. The virus in the blister is mixed and spreads to cause extensive herpes. This is the cause of herpes zoster.
It is caused by varicella-zoster virus infection in the semilunar ganglion or a branch of the trigeminal nerve. Patients who are receiving radiation therapy or immunosuppressive therapy are prone to this disease. After the onset, they are immunized for life and rarely relapse. Mainly caused by viral infections.
Prevention
Eye herpes zoster prevention
For the prevention of this disease, it is necessary to pay attention to enhance physical fitness, mental well-being, avoid overwork, lack of sleep, eyelid trauma and so on.
After the onset of care is also particularly important, try to keep the local clean and dry, timely clear the exudate pus, not suitable for water treatment or Chinese medicine decoction directly fumigation, to avoid rubbing the affected part by hand.
Complication
Ocular herpes zoster complications Complications keratitis iritis
Among the complications, keratitis and iritis are more common.
Symptom
Ocular herpes zoster symptoms common symptoms keratitis chills scarring
1, the disease site: often occurs in the first branch of the trigeminal nerve (eye branch), distributed in the hair of the scalp, the forehead and upper skin; sometimes also invade the second branch, the lesion is distributed in the lower eyelid, cheek and upper lip, It is characterized by infringement of only one side, ending in the midline formation of the forehead and a significant demarcation.
2, the symptoms : early onset, the distribution of trigeminal nerves have severe neuralgia, fear of light, tears and so on.
3, physical signs: a few days after the onset of skin flushing, swelling, clusters of numerous transparent, the size of the band is arranged, the blister is initially colorless and transparent, followed by turbid purulent, crusting in a few weeks, due to invasion of the dermis, legacy Permanent scars, often complicated by keratitis and iridocyclitis, affect vision, occasionally eye muscle paralysis, in addition to severe cases may be associated with fever, chills, discomfort and other systemic symptoms, or local lymphadenopathy and tenderness.
Examine
Eye herpes zoster examination
1. Comprehensive eye examination
Including slit lamp examination and fluorescein staining, intraocular pressure measurement, dilated examination of the optic nerve and retina.
2. Whole body examination.
Detailed medical history and local physical examination are generally not difficult to diagnose.
3. Laboratory examination: no specificity, eosinophils may increase in the blood. The lgE check is likely to increase.
Diagnosis
Diagnosis of ocular herpes zoster
diagnosis:
Diagnosis can be performed based on clinical manifestations and examinations.
Differential diagnosis:
The disease should be distinguished from the sinus red sputum in Chinese medicine. Although both diseases are red and red in the eyelids, the lesions of the sinus are limited to the sacral chords, which do not affect the skin surface. Eye herpes zoster is mainly caused by the lesions of the eyelid skin, and generally does not affect the chord.
