Retinal Issues in High Myopia: Concerns and Recommendations - Ophthalmology

More Info

---

Hello! Thank you for your questions regarding high myopia and its associated retinal issues. As someone with extremely high myopia (around -1200 to -1300 diopters), it's understandable to have concerns about your eye health, especially with the recent increase in floaters. Let’s address your questions one by one.

1. Physical Activity and Eye Safety: Your understanding of engaging in physical activities while being cautious about eye safety is generally correct. High myopia can lead to a thinner retina, which may increase the risk of retinal detachment, particularly with activities that involve high impact or potential trauma to the head and eyes. While many forms of exercise can be safely performed, it is crucial to avoid activities that could lead to direct trauma to the eyes. For instance, in judo, where falls and impacts are common, you should take extra precautions. It might be wise to consult with your ophthalmologist about specific exercises and sports that you can safely participate in. They may recommend avoiding high-impact sports or activities that involve rapid head movements or potential collisions. Always prioritize protective measures, such as wearing appropriate eyewear during sports.

2. Night Shifts and Retinal Health: Working night shifts and staying up late can have various effects on your overall health, including your eye health. While there is no direct evidence that night shifts cause retinal detachment, chronic sleep deprivation can lead to eye strain and fatigue, which may exacerbate existing visual disturbances, such as floaters. It's essential to maintain a healthy sleep schedule as much as possible, even when working nights. Ensure that you take regular breaks during your shifts to rest your eyes and reduce strain. If you notice any changes in your vision or an increase in floaters, it’s crucial to seek an eye examination promptly.

Regarding your anxiety about floaters, it's important to remember that while they can be bothersome, they are often benign, especially if your eye examinations have not shown any signs of retinal tears or detachment. However, given your high myopia, you should continue to have regular eye check-ups to monitor your retinal health. If you experience sudden changes in your floaters, flashes of light, or a shadow in your peripheral vision, you should seek immediate medical attention, as these could be signs of a retinal detachment.

In summary, while you can continue to engage in most physical activities with caution, it’s essential to avoid high-risk sports that could lead to eye trauma. Additionally, managing your work schedule to ensure adequate rest and eye care is vital. Regular follow-ups with your eye care provider will help ensure that any potential issues are caught early, allowing for timely intervention if necessary. Stay proactive about your eye health, and don’t hesitate to reach out to your ophthalmologist with any concerns. Wishing you the best in your health and well-being!
