Eyelid herpes zoster

Introduction to eyelid herpes zoster The typical lesions of herpeszoster are mostly in the first branch of the trigeminal nervethe branches of the ocular nerve (frontal nerve, lacrimal gland nerve and nasal ciliary nerve) or the distribution of skin in the third main branch (less common). A clustered blister-like rash occurs. But it does not cross the central boundary of the ankle and nose, but is limited to one side. Herpes zoster is divided into two types according to the cause: epidemic (viral) and symptomatic. The former may be caused by a type of varicella virus infection, while the latter is a symptomatic herpes zoster, which is actually a latent infection that has been lurking in the past. The hidden dangers, and the lesions that are actively stimulated by the new induced stimuli, are not substantially different from the epidemic types, and the latter are more common in young people and are prone to recurrence. basic knowledge The proportion of sickness: 0.4% Susceptible people: no special people Mode of infection: non-infectious Complications: keratitis iridocyclitis

Causes of herpes zoster

It is caused by acute viral infection of the trigeminal semilunar ganglion or one of its main branches, but its mechanism of invasion is not fully understood. It often occurs in frail elderly people, with recurrence and primary points. The former is rare.

Concurrent keratitis or iridocyclitis.

Orbital herpes zoster symptoms Common symptoms Herpes zoster-like appearance Nausea severe pain Cold keratitis Scarring lymphadenopathy Herpes Herpes Eye muscle paralysis

1. There are different pre-existing symptoms before the onset, such as chills, nausea, vomiting and other general malaise. After a few days, there is severe neuropathic pain in the ward, and there are symptoms such as fear of light, tearing, and redness of the skin.

2, the formation of clustered transparent small blisters on the skin of the eyelids, arranged in a strip shape, followed by turbidity to form pustules, rupture and erosion, and finally dry and crusted, the general course of disease is about 2 weeks, after the dislocation, leaving a shallow pigmentation In the scar, in some cases, herpes purulent formation of deep ulcers, combined with the corresponding lymph nodes, leaving a permanent scar after healing, each of which can be judged to have suffered from the disease, sometimes bleeding around the herpes, or deep in the eyelids Seesaw inflammation.

3, eyelid skin clustering herpes according to the location of the first branch of the trigeminal nerve, generally appear in the third branch of the trigeminal nerve (ocular nerve) distribution, spread over the forehead, sometimes invading the second branch The lesions are distributed in the lower jaw face and upper lip skin, and never cross the forehead midline, but invade it, the third branch is rarely affected, and the three main branches are involved at the same time. The neuralgia can last 1~ 2 months, sometimes months, disappeared in a few years, and the feeling of delay is numb.

4, herpes appears in the nose and nose, it indicates the involvement of the nasal ciliary nerve, causing cornea, iris, sclera, uvea, optic nerve, retina and the possibility of involving the ophthalmoplegia. Corneal involvement, visual loss, matrix opacity or even ulceration, such as invasion of the iris, even without pupillary atresia, secondary glaucoma can occur, but not common.

Eyelid herpes detection

History

The duration of rash pain, the history of immunodeficiency, and the risk factors for acquired immunodeficiency syndrome.

2. Comprehensive eye examination

Including slit lamp examination and fluorescein staining, intraocular pressure measurement, dilated examination of the optic nerve and retina.

3. Whole body examination

Diagnosis and diagnosis of herpes zoster

diagnosis

1. The first branch of the unilateral trigeminal nerve and/or the second branch distribution area has a hereditary herpes, no more than the midline of the face.

2, before the emergence of herpes, there may be fear of light, tears, severe pain along the nerve spasm distribution, local skin redness and general malaise and other symptoms.

3, herpes is of different sizes, arranged in a strip shape, initially colorless and transparent, followed by opacity and purulent, after about 2 weeks, the scars fall off, leaving scars or pigmentation.

4, often complicated by conjunctivitis, keratitis, iridocyclitis, occasionally eye muscle paralysis.

Differential diagnosis

Eyelid herpes simplex and allergic eyelid inflammatory rash, etc., easy to be confused with other skin herpes, should be noted.
