High Myopia: Concerns, Treatments, and Lifestyle Tips - Ophthalmology

More Info

High myopia, or severe nearsightedness, is a condition that can lead to various complications, including retinal thinning, which you mentioned in your concerns. It’s understandable to feel anxious about the varying measurements of your eyesight and the potential implications for your vision. Let's address your questions one by one.

1. Variability in Measurements: The differences in your prescription readings can be attributed to several factors, including the method of measurement, the equipment used, and even the condition of your eyes on the day of the exam. It's not uncommon for different eye care professionals to arrive at slightly different results, especially in cases of high myopia. The term "pseudomyopia" refers to a temporary condition where the eye may appear more nearsighted due to spasm of the eye's focusing muscle (ciliary muscle). The eye drops prescribed to you are likely intended to relax this muscle, potentially providing a more accurate measurement of your refractive error. It’s advisable to follow the doctor’s instructions regarding the eye drops and to have a follow-up appointment to reassess your vision after the treatment.

2. New Glasses and Contact Lenses: If your current glasses allow you to see clearly, you may not need to rush into getting a new prescription. However, if you notice any changes in your vision or discomfort, it would be prudent to have another eye exam. As for contact lenses, both soft and rigid gas permeable lenses can be suitable for high myopia. Soft lenses are generally more comfortable, while rigid lenses can provide sharper vision and may be better for your eye health in the long run. A consultation with your eye care provider can help determine the best option for you.

3. Flying with High Myopia: Generally, individuals with high myopia can fly without issues. However, it’s wise to be cautious, as changes in altitude can affect intraocular pressure. If you have any underlying retinal issues, such as thinning or tears, it’s best to discuss your travel plans with your eye doctor to ensure that you’re not at increased risk for complications.

4. Genetic Factors: High myopia can have a hereditary component. If you have high myopia, there is a possibility that your children may also develop it, but this is not guaranteed. Environmental factors, such as time spent outdoors and near work, also play a significant role in the development of myopia.

5. Lifestyle and Eye Care: In addition to regular eye exams, there are several lifestyle modifications you can adopt to help manage high myopia. These include:
- Outdoor Activities: Spending more time outdoors has been shown to reduce the risk of developing myopia in children and may help slow its progression in adults.

- Proper Lighting: Ensure that you have adequate lighting when reading or using screens to reduce eye strain.

- Breaks from Screens: Follow the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

- Healthy Diet: A diet rich in antioxidants (found in fruits and vegetables) can support overall eye health. Omega-3 fatty acids, found in fish, may also be beneficial.

- Regular Check-ups: Continue with regular eye examinations to monitor your condition and catch any potential complications early.

In summary, while high myopia presents certain risks, proactive management through regular check-ups, appropriate eyewear, and lifestyle adjustments can help maintain your vision and overall eye health. If you have further concerns or experience any changes in your vision, don’t hesitate to reach out to your eye care professional for personalized advice.
