High Myopia: Risks and Management for College Students - Ophthalmology

High myopia


Hello, doctor.
I am a university student with severe myopia.
My right eye is -9.00 and my left eye is -9.75.
I have regular fundus examinations and take lutein supplements.
I would like to ask the doctor: even with regular check-ups, is the risk of blindness still high for those with severe myopia? I worry every day about possibly going blind, which causes me a lot of distress.
Thank you, doctor.

Reduce screen time, allow your eyes to rest, and have regular check-ups; there is actually no need to worry too much.

High myopia, defined as a refractive error greater than -6.00 diopters, poses significant risks to eye health, particularly for young adults like yourself. With your measurements of -9.00 diopters in the right eye and -9.75 diopters in the left, you fall into the category of high myopia, which is associated with various ocular complications that can lead to severe vision impairment or even blindness.

One of the primary concerns with high myopia is the increased risk of developing conditions such as retinal detachment, myopic macular degeneration, and glaucoma. These conditions can arise due to the elongation of the eyeball, which is characteristic of high myopia. The stretching of the retina can lead to thinning and potential tears, while changes in the macula can affect central vision. Regular eye examinations are crucial for early detection of these complications, and it’s good to hear that you are already undergoing periodic eye checks.

Despite your proactive approach to eye health, including regular check-ups and supplementation with lutein, it is understandable to feel anxious about the potential for vision loss. The risk of blindness is indeed higher in individuals with high myopia compared to those with normal vision. However, it is important to note that not all individuals with high myopia will experience severe complications. The key is to maintain a close relationship with your eye care provider, who can monitor your condition and recommend appropriate interventions if necessary.

In terms of management, there are several strategies that can help mitigate the risks associated with high myopia:
1. Regular Eye Exams: Continue with your routine eye examinations. Your eye doctor will look for early signs of complications and can provide timely treatment if needed.

2. Protective Measures: Wearing UV-blocking sunglasses can help protect your eyes from harmful rays, which may contribute to retinal damage over time.

3. Lifestyle Adjustments: Reducing screen time and taking regular breaks during prolonged near work can help alleviate eye strain. The 20-20-20 rule is a helpful guideline: every 20 minutes, look at something 20 feet away for at least 20 seconds.

4. Healthy Diet: A diet rich in antioxidants, vitamins, and minerals can support overall eye health. Foods high in omega-3 fatty acids, leafy greens, and colorful fruits and vegetables are particularly beneficial.

5. Vision Correction: Ensure that your glasses or contact lenses are up to date. In some cases, refractive surgery may be an option, but this should be discussed thoroughly with your eye care professional.

6. Stress Management: Anxiety about potential vision loss can be overwhelming. Consider engaging in stress-reducing activities such as mindfulness, yoga, or talking to a counselor if your worries become too burdensome.

While the risk of severe complications exists, many individuals with high myopia lead fulfilling lives without significant vision loss. Staying informed and proactive about your eye health is the best approach to managing your condition. If your anxiety persists, discussing your concerns with your eye doctor or a mental health professional may provide additional support and reassurance. Remember, you are not alone in this, and there are resources available to help you navigate your concerns about high myopia.
