What is conjunctivitis pseudomembrane?
Recently, conjunctivitis pseudomembrane has become one of the hot health topics on the Internet. Especially in the spring and summer seasons, eye diseases are more common, and many people are confused by this symptom. This article will explain in detail the definition, causes, symptoms and treatment of conjunctivitis pseudomembrane, and attach relevant data for reference.
1. Definition of conjunctivitis pseudomembrane
Conjunctivitis pseudomembrane refers to a layer of gray-white or yellow film-like material formed on the surface of the conjunctiva during conjunctivitis (commonly known as "pink eye") caused by bacterial or viral infection. This layer of pseudomembrane is composed of fibrin, inflammatory cells and necrotic tissue. It is usually attached to the surface of the conjunctiva. Forcible removal may cause bleeding.
2. Causes of conjunctivitis pseudomembrane
The formation of conjunctivitis pseudomembrane is closely related to the following factors:
| Type of cause | Specific instructions |
|---|---|
| bacterial infection | Such as Streptococcus, Staphylococcus, etc., which secrete toxins and trigger inflammatory reactions. |
| viral infection | Adenovirus, herpes simplex virus, etc. can cause pseudomembrane formation. |
| chemical irritation | Strong acid, strong alkali or foreign matter irritates the conjunctiva and triggers an exudation reaction. |
| allergic reaction | Allergens such as pollen and dust mites induce severe allergic conjunctivitis. |
3. Symptoms of conjunctivitis pseudomembrane
Patients usually experience the following typical symptoms:
| Symptoms | Performance characteristics |
|---|---|
| bloodshot eyes | The conjunctival blood vessels are dilated and the whites of the eyes are red. |
| pseudomembrane coverage | The gray-white membrane is attached to the palpebral conjunctiva and can be wiped off but is prone to recurrence. |
| increased secretions | Yellow purulent discharge (bacterial) or watery discharge (viral). |
| Foreign body sensation/pain | There is a friction sensation when blinking, and in severe cases, it is accompanied by photophobia and tearing. |
4. Treatment methods and precautions
Treatment options vary depending on the cause:
| treatment type | Specific measures |
|---|---|
| drug treatment | Bacterial: antibiotic eye drops (such as levofloxacin); viral: antiviral drugs (such as acyclovir). |
| Pseudo membrane treatment | The doctor uses a saline swab to gently remove it, but do not tear it off by yourself. |
| adjuvant treatment | Use cold compresses to relieve swelling and artificial tears to lubricate the eyes. |
| Precautions | Avoid rubbing your eyes, wash your hands frequently, and do not share towels/cosmetics. |

6. Summary
Conjunctivitis pseudomembrane is one of the serious manifestations of conjunctivitis, and timely medical treatment is required to determine the cause. Spring is the peak season for conjunctivitis, so paying attention to personal hygiene and avoiding contact with sources of infection is key.
