What medicine is good for myopia?
In recent years, the problem of myopia has become one of the health topics of global concern, especially the rate of myopia among teenagers continues to rise. Many patients and their families are looking for medication to treat myopia. So, what medicine is good for myopia? This article will answer this question for you based on the hot topics and hot content on the Internet in the past 10 days.
1. Causes and Current Situation of Myopia
Myopia is caused by the eyeball being too long or the curvature of the cornea being too steep, causing light to focus in front of the retina, resulting in blurred distance vision. According to data from the World Health Organization (WHO), there are more than 2 billion myopia patients worldwide, and the myopia rate among Chinese teenagers is as high as over 70%.
| area | Myopia rate among teenagers | growing trend |
|---|---|---|
| China | More than 70% | Rising year by year |
| USA | About 40% | slow growth |
| Europe | 30%-50% | stable |
2. Research progress in drug treatment of myopia
Currently, there are no specific drugs that can completely cure myopia, but some drugs have shown certain effects in controlling the progression of myopia. The following are several drugs that have been hotly discussed on the Internet in the past 10 days:
| Drug name | Mechanism of action | Effect | Things to note |
|---|---|---|---|
| Atropine eye drops | Relax the ciliary muscles and slow down the growth of the axial length of the eye | Can delay the progression of myopia by about 50% | May cause mydriasis and photophobia |
| Aescin and Digitalis Diglycoside Eye Drops | Improve retinal blood circulation | Relieve visual fatigue and indirectly assist in controlling myopia | Requires long-term use |
| Vitamin A/D supplements | Promote retinal health | Auxiliary effect, limited effect | Overdose may be toxic |
3. Comprehensive prevention and control plan recommended by experts
Relying solely on medication cannot completely solve the problem of myopia. The following are comprehensive prevention and control measures recommended by experts:
1.Optical correction:Wearing glasses or orthokeratology lenses (OK lenses) can effectively correct vision and delay the progression of myopia.
2.Outdoor activities:At least 2 hours of outdoor activities every day and exposure to natural light can help inhibit the growth of the axial length of the eye.
3.Eye habits:Follow the "20-20-20" rule (look 20 feet away for 20 seconds every 20 minutes) to reduce the time you spend using your eyes at close range.
4.Regular inspection:Conduct a vision examination every 6 months and adjust the prevention and control plan in a timely manner.
4. Precautions when using drugs
1. Atropine eye drops must be used under the guidance of a doctor and cannot be purchased by yourself.
2. Drugs may cause side effects, such as mydriasis, blurred near vision, etc. The pros and cons need to be weighed.
3. Children should be treated with special caution to avoid affecting their growth and development.
5. Future research directions
Scientists are studying more possible drug treatment options, including:
| Research direction | progress | expected effect |
|---|---|---|
| dopamine receptor agonist | Animal experiment stage | May regulate eyeball growth |
| gene therapy | basic research | Myopia is expected to be cured in the long run |
| biomaterial implants | clinical trial | May control axial growth |
6. Answers to Frequently Asked Questions by Patients
Q: Is taking lutein useful for myopia?
A: Lutein mainly improves retinal health and has limited effect on controlling the progression of myopia.
Q: Can Chinese medicine treat myopia?
A: There is currently insufficient scientific evidence that Chinese medicine can reverse myopia. Some Chinese medicine may relieve visual fatigue.
Q: Can vitamins prevent myopia?
A: Vitamins A and D are helpful for eye health, but they cannot prevent or treat myopia alone.
7. Summary
At present, the effect of drugs in treating myopia is limited. Atropine eye drops are a relatively effective choice, but it needs to be combined with other prevention and control measures. The key to preventing myopia is to develop good eye habits and increase time for outdoor activities. Patients should develop a personalized treatment plan under the guidance of a professional doctor, and do not believe in exaggerated "miracle drugs".
As medical research advances, more effective treatments for myopia may emerge in the future. At this stage, comprehensive prevention and control is still the best strategy to deal with myopia.
