Retinal Issues in High Myopia: Risks and Prevention - Ophthalmology

More Info

---

Hello! Thank you for reaching out with your concerns regarding high myopia and retinal issues. It's completely understandable to feel anxious about your eye health, especially when dealing with high myopia (around 750 degrees in your case). Let’s address your questions one by one.

1. Risk of Retinal Detachment in High Myopia: Individuals with high myopia have a higher risk of retinal detachment due to the elongation of the eyeball, which can lead to thinning of the retina. However, if you have not experienced any trauma or engaged in high-risk activities, the likelihood of sudden retinal detachment is relatively low. Regular monitoring through eye exams is essential. Your doctor’s recommendation for a follow-up in six months is a good practice, as it allows for ongoing assessment of your retinal health.

2. Computer and Mobile Device Use: Prolonged use of computers and mobile devices can lead to eye strain and discomfort, but it does not directly increase the risk of retinal detachment. The key concern with high myopia is the structural integrity of the retina, rather than the duration of screen time. If you do not have any signs of macular degeneration or other retinal diseases, your risk remains primarily associated with the degree of myopia rather than screen time alone.

3. Using 3C Products with Rest: Following the 20-20-20 rule—taking a 20-second break to look at something 20 feet away every 20 minutes—can help reduce eye strain. While this practice is beneficial for overall eye comfort, it does not significantly alter the risk of retinal tears or detachment. The primary risk factors remain related to the structural changes in the eye associated with high myopia.

4. Symptoms of Retinal Detachment: Symptoms of retinal detachment can indeed occur suddenly and may include the appearance of floaters, flashes of light, or a shadow or curtain over part of your vision. It’s crucial to be aware of these signs and seek immediate medical attention if they occur. Regular eye examinations are vital for early detection of any changes in your retina.

5. Diet and Eye Health: While there is no specific diet that can prevent retinal detachment, maintaining a healthy diet rich in antioxidants (such as vitamins C and E, omega-3 fatty acids, and lutein) can support overall eye health. Foods like leafy greens, fish, nuts, and fruits can be beneficial. Staying hydrated and managing overall health conditions (like diabetes and hypertension) is also crucial for maintaining retinal health.

In summary, while high myopia does increase the risk of retinal issues, regular check-ups and a healthy lifestyle can help manage this risk. If you experience any sudden changes in your vision, do not hesitate to contact your eye care provider immediately. It’s important to stay informed and proactive about your eye health, and I encourage you to continue your regular eye exams as recommended by your doctor. Remember, you are not alone in this, and many people with high myopia lead healthy lives with proper care and monitoring. Take care!
