High Myopia: Risks and Long-Term Eye Health Concerns - Ophthalmology

More Info

---

High myopia, often defined as a refractive error greater than -6.00 diopters, poses several risks to eye health, particularly as one ages. Your concerns about potential deterioration of vision and the likelihood of retinal complications are valid, especially given your current prescription of -5.75 in the left eye and -6.50 in the right eye at the age of 20.
1. Will Myopia Deteriorate with Age?
The progression of myopia can vary significantly from person to person. In many cases, myopia stabilizes in early adulthood, but some individuals may experience continued progression into their 30s or even 40s. Factors influencing this progression include genetics, environmental factors, and lifestyle choices. For instance, excessive near work, such as prolonged use of computers or smartphones, can exacerbate myopia. However, it is not guaranteed that your myopia will worsen significantly as you age. Regular eye examinations are crucial for monitoring your vision and making necessary adjustments to your corrective lenses.

2. Risk of Retinal Complications
You are correct that individuals with high myopia are at a greater risk for retinal complications compared to those with lower degrees of myopia. The risk of conditions such as retinal detachment, myopic macular degeneration, and choroidal neovascularization increases with the severity of myopia. Studies indicate that while the risk is higher, not all individuals with high myopia will experience these complications. The prevalence of retinal changes in high myopia can be significant, but it is essential to remember that many people with high myopia maintain good vision throughout their lives without severe complications.

To address your anxiety, it is important to focus on proactive measures:
- Regular Eye Exams: Continue to have regular check-ups with your eye care professional. These exams can help detect any early signs of complications, allowing for timely intervention.


- Healthy Eye Habits: Adopt good visual hygiene practices. This includes taking breaks during prolonged near work (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds), ensuring proper lighting while reading or using screens, and maintaining a comfortable distance from screens.

- Lifestyle Choices: Engage in outdoor activities, as studies suggest that spending time outdoors may help slow the progression of myopia in children and young adults. A balanced diet rich in vitamins and antioxidants can also support overall eye health.

- Stress Management: Anxiety about vision loss can be overwhelming. Consider discussing your concerns with your eye doctor, who can provide reassurance and strategies to manage your anxiety. Support groups or counseling may also be beneficial.

In summary, while high myopia does carry risks for long-term eye health, many individuals lead healthy lives with proper care and monitoring. Your current prescription does not automatically predict severe deterioration or complications in the future. By staying informed and proactive about your eye health, you can significantly mitigate risks and maintain your vision.
