Is herpetic conjunctivitis serious?

Herpetic conjunctivitis is a very common disease in daily life. It can cause great harm to people's eyes, so patients need to seek medical treatment in time. Herpetic conjunctivitis is caused by microbial infection such as bacteria and viruses. According to the cause of the disease, it can be divided into two types: bacterial and viral. People need to judge the type of their disease and then take the right medicine. As long as they seek medical treatment in time, they can fully recover.

1. Overview

1. The most common microbial infections are bacteria, viruses, fungi, and chlamydia.

2. Physical sandstorms and chemical drugs.

3. Allergic and immune.

2. Classification of herpetic conjunctivitis

According to the cause, it can be divided into bacterial and viral.

According to the course of the disease, it can be divided into acute and chronic.

3. Clinical manifestations of herpetic conjunctivitis

1. Conjunctival congestion and edema

Localized to a specific area, vesicular conjunctivitis.

Diffuse bright red color, with marked hyperemia in the fornix.

The congested blood vessels are on the surface of the conjunctiva, and when you push, the blood vessels move with you. After applying 1% epinephrine eye drops, the congestion disappears, and in severe cases, conjunctival edema occurs.

2. Increased secretions

Bacterial serous, mucous, purulent.

Viral watery, serous.

Allergy or dry eye sticky stringy.

3. Subconjunctival hemorrhage

4. Nipples hyperplasia and follicle formation

Papillary hyperplasia is the excessive proliferation and polymorphonuclear leukocyte infiltration of the conjunctival epithelium. Under the slit lamp, some dilated capillaries can be seen in the center of each papilla, spreading out in a spoke-like manner, showing a small papillary or velvety appearance. A giant papilla is greater than 1 mm in diameter, vernal conjunctivitis, and corneal contact lenses.

Follicular conjunctival epithelial lymphocytes are localized and accumulate in a hemispherical shape. There are no blood vessels in the center, and blood vessels surround the follicles. This is a characteristic seen in most viral conjunctivitis.

Immune conjunctivitis (immunologic conjunctivitis, vernal keratoconjunctivitis, vernal catarrh) mostly occurs in spring and summer, improves in autumn, and is common in men under 20 years old.

Causes

Unclear, plant pollen allergy. Type I hypersensitivity, cellular immunity, IgG antibodies. The causative allergens may be plant pollen, protein components of various microorganisms, animal dander and feathers, etc.

Clinical manifestations

Symptoms include extreme itching, photophobia, tearing, and foreign body sensation.

1. The upper eyelid conjunctiva of the tarsal conjunctiva type does not invade the fornix conjunctiva. It is hard and flat, with pink nipples of varying sizes, like paving stones. There is a layer of milky membrane on the surface of the nipples, and the secretions are sticky.

2. Limbal type: Hypertrophy of the corneal papilla occurs at the limbus, and the limbus has a yellow-brown or dirty red, thickened, gelatinous appearance. It is common in the palpebral fissure area and is common in black people.

3. Mixed type: The above two types exist at the same time.

treat

1. Eliminate the cause

2. Drug treatment: 2-4% sodium cromoglycate, 1% epinephrine eye drops to improve symptoms, hormone eye drops.
