Herpes simplex is a common contagious skin disease that can occur anywhere on the body. Herpes simplex keratitis is also caused by a viral infection. Some symptoms of herpes simplex virus keratitis are obvious to patients and there is a certain degree of pain.

Herpes simplex keratitis symptoms

Typical symptoms: Mainly manifested as systemic fever and swollen and painful preauricular lymph nodes. Eye damage is extremely rare, mainly including: 1) Herpetic blepharitis: The blisters on the eyelid rash dry up after one week, and the scabs fall off without leaving painful scars. 2) Acute follicular conjunctivitis: conjunctival congestion, swelling, follicular hyperplasia, and even the appearance of pseudomembranes. 3) Punctate or dendritic keratitis:

1. Primary infection:

Primary infection only occurs in those with negative serum antibodies, which is more common in children. Infants under 6 months old can obtain anti-herpes simplex virus antibodies from the mother through the placenta. Factor-induced infection is rare, and then as the antibodies gradually disappear, children aged 1 to 3 years are most susceptible to infection. By the age of 5, 60% are infected, and by the age of 15, more than 90% are infected.

The main symptoms of primary infection are fever and swollen and painful lymph nodes before the ears. Eye damage is extremely rare and mainly includes:

1) Herpetic blepharitis:

After a week, the blisters of the eyelid rash dry up, form scabs and fall off without leaving painful scars.

2) Acute follicular conjunctivitis:

The conjunctiva is congested, swollen, follicularly proliferates, and even pseudomembranes appear.

3) Punctate or dendritic keratitis:

About 2/3 of patients with the above two symptoms may develop changes of punctate keratitis or dendritic keratitis.

2. Recurrent infection:

If there has been a herpes virus infection in the past and antibodies are present in the serum, under the action of provocative factors, the first attack or recurrence is considered a recurrent infection. The source of infection is mostly endogenous (that is, the virus exists in the cornea, lacrimal glands, and conjunctival trigeminal ganglion), and a few may also be exogenous.
