How is viral keratitis treated, and is it serious?

1 Herpes simplex virus keratitis: (1) Anti-simplex scar virus drugs. Superficial corneal lesions:

0 1 sulfonate (herpes net) eye drops can be used once an hour, 0 1 eye ointment can be added in the evening, and ribavirin eye drops can be added. 0 5 ribavirin eye drops every 1 to 2 hours may also be preferred. Medium and deep corneal stromal lesions or herpes simplex uveitis:

0 05 acetabine (cyclocytidine) eye drops or 0 5 ribavirin eye drops can be used once an hour; or subconjunctival injection of acetabine 3-5 mg, once a day, 5-10 times in a row; 0 1 -1 acyclovir eye drops can also be used, with eye drops every 1 to 2 hours. (2) Immune enhancer, levamisole can be used, 50mg each time, orally 2-3 times a day, for 10-14 days as a course of treatment. After the interval of 2 weeks, repeat the treatment for 1-2 years.

Transfer factors, interferons and their inducers can also be selected. (3) Adrenocorticotropic hormone: For patients with immunoreactive edema infiltration with too strong non-ulcerative stromal lesions, adrenocorticosteroid can be used in combination with antiviral drugs, generally 0 05 flumethasone eye drops, 2-3 times a day, increase or decrease the number of eye drops according to the changes in the condition.

It is forbidden for patients with ulcers of epithelial type and stromal layer type. (4) Others: The preferred method for epithelial patients is to gently rub the lesion area with a normal saline cotton swab to remove the infected epithelial cells at the edge of the ulcer, and at the same time drop antiviral drugs; With no water

Chemical debridement such as iodine tincture and 3-carbolic acid also has some efficacy. Topical ophthalmic medication and support for symptomatic ** Same as bacterial keratitis. 2 Zoster virus keratitis:

1) Antiviral drugs: 0 5 Ribavirin eye drops: 1 time every 1-2 hours.

0 1 Iodoside (herpes net) eye drops: 1 eye drop per hour. 3 Acyclovir eye drops:

Eye drops 1 time every 1-2 hours. 0 05 Ancitabine eye drops, 1 time every 1-2 hours. (2) Adrenocorticotropic hormones:

Patients with uveitis or discoid keratitis can be treated with topical adrenocorticosteroid eye drops as appropriate. (3) Immune enhancers: levamisole, transfer factor, interference cord, etc. can be selected.

4) Others: 1 Atropine eye drops dilated pupils, indomethacin oral, supplemented B vitamins, vitamin C, cystine, sodium pantothenate, etc.

Keratitis** should be noted at the same time as the following ten contraindications:

1. Avoid alcoholAlcohol can reduce the body's immunity and speed up the reproduction of the virus, so patients with viral keratitis must quit alcohol and alcoholic beverages.

2. Avoid mutton due to the deep corneal lesions of patients with viral keratitis, which is a manifestation of immune response, and eating mutton can aggravate this immune response and lead to aggravation of the disease, so patients with viral keratitis should not eat mutton.

3. Do not apply hot compresses to the eyes because people's corneas are in a cooler environment most of the time every day (except sleep) and have become accustomed to it. If they are suddenly treated with a higher temperature when they are sick, it is tantamount to adding fuel to the fire and causing them to suffer from high temperature and lack of oxygen.

Fourth, the number of eye drops should be guaranteed 6 to 8 times a day, and it cannot be reduced. The reason is very simple, medicine is like using soldiers, this is like fighting a war, it would take 100,000 elite soldiers to conquer a city, if only 50,000 troops were sent, the result can be imagined.

Five taboos do not suppress the lacrimal sac when the patient does not press the lacrimal sac during the medication, about 70% of the eye drops into the eye will flow into the lacrimal sac, if this channel is not blocked at this time, the efficacy of the drug will be greatly reduced.

Six taboos to bandage the eyeBandaging the eye can increase the temperature of the conjunctival sac and increase the secretion, which is conducive to the reproduction of bacteria and viruses, and the gauze used may also scratch the cornea.

7. Do not close your eyes and bow your head, this action may cause blood congestion in the patient's eyes and aggravate the condition.

Eight taboos will be accepted when they see a good condition, and only after the illness is **, the patient can stop the medicine according to the doctor's instructions.

When the condition is quickly controlled, the cornea is restored to transparency, and the vision is improved, they mistakenly think that their disease has been abandoned, and they take the initiative to stop the drug, which leads to serious consequences. They don't understand that hormone usage is specific and needs to be withdrawn in a decreasing manner.

When the effect of a certain antiviral drug, such as an inhibitory antiviral, is not satisfied, the patient can switch to other types of antivirals, such as killing antivirals, under the guidance of doctors.

You have to go to the hospital for diagnosis and treatment in time, and you can't delay. I just ** last week, and I can understand the patient's eagerness to be cured. I was on anti-inflammatory injections for 4 days.

Once you have herpes simplex virus keratitis, you should be prompted**. **Medications, surgeries, etc. may be used.

1. Antiviral drugs are mainly used in the drug, such as iodoside, also known as herpes net, which is mainly suitable for the first case, and it is advisable to switch to other drugs for multiple cases; Cytarabine has a certain effect, but it is highly toxic to normal cells, so its derivative cyclocytidine is commonly used; Riboside triazole is a broad-spectrum antiviral drug with good efficacy and low toxicity to normal cells; Acyclic guanosine is a more effective antiviral drug, especially for herpes virus, which has obvious inhibitory effect; Other antiviral drugs such as cytarabine adenosine, trifluorothymine nucleoside, etc.

Adrenocorticosteroids can also be used for herpes simplex virus keratitis, because it has the effect of inhibiting corneal immune response and anti-inflammatory, and is often used in the later stage of herpes simplex virus keratitis, but the following principles should be mastered:

1. Superficial inflammation of the epithelium or cornea is prohibited. Because it can activate the activity of viruses and collagenase, promote the reproduction of viruses, and make the lesions develop deeply. It also inhibits epithelial regeneration and even causes ulcer perforation.

2. It is only used for patients with deep inflammatory reaction and no ulcer. Because the pathogenesis of deep HSK, especially discoid keratitis, is associated with allergy to viral antigens, corticosteroids are reasonable, but antiviral drugs should be used at the same time. 1 2 days with fluorescein coloring, if there is an ulcer, immediately stop, according to the ulcer treatment.

2. Herpes simplex virus keratitis can also be surgical**, according to the condition to choose the surgical method, the commonly used methods are: mechanical debridement, anterior chamber puncture, conjunctival flap covering, corneal transplantation, etc.

Antiviral eye drops are generally used.

Keratitis in children is usually caused by infectious keratitis. It has a lot to do with the baby's lively nature, often rubbing his eyes with his hands and not paying attention to eye hygiene. This case **.

The first thing is to let the baby pay attention to eye hygiene and not continue to rub his eyes with dirty hands.

Second, we should go to the hospital in time to check and clarify what type of keratitis it is, and then give targeted anti-infection**, for example, viral keratitis should use antiviral drugs, such as ganciclovir eye drops; In bacterial keratitis, antibiotic drugs such as tobramycin eye drops should be used.

If children can't cooperate, tears after eye drops will easily make the eye drops rinse out, and it will not work, so in this case, we can give the baby eye ointment and eye gel, so that because the gel is more viscous and not easy to be rinsed out by tears, there are more drugs left in the eyes to play a role.

The baby is only four years old, and you can't say anything about corneal transplantation, and you'd better use traditional Chinese medicine** Chinese medicine**Viral keratitis is not at all**.

It's not enough to go to a big hospital once, but a few times and the doctor will be cured, and the doctor wants a little more money to prescribe a good medicine.
