Eye Flashes and Retinal Degeneration: Your Questions Answered - Ophthalmology

---

Hello! Thank you for your detailed questions regarding your eye health, particularly concerning retinal degeneration and the symptoms you are experiencing. Let's address your concerns one by one.

1. Flashes of Light with Blinking: The phenomenon you describe, where you see a bright spot or flash of light every time you blink, could be related to the vitreous gel in your eye. As we age or in cases of myopia (nearsightedness), the vitreous can begin to liquefy and pull away from the retina. This can lead to sensations of flashes or floaters. The bright spots you see may be due to the vitreous tugging on the retina or even light reflecting off the vitreous itself. If these flashes are persistent or accompanied by other symptoms like a sudden increase in floaters or a shadow in your vision, it is crucial to seek immediate medical attention, as these could indicate a retinal tear or detachment.

2. Dietary Supplements for Retinal Health: Regarding your question about lutein and zeaxanthin (often found in supplements for eye health), studies suggest that these antioxidants can help protect the retina from oxidative stress and may slow the progression of age-related macular degeneration (AMD). While they may not reverse retinal degeneration, they can contribute to overall eye health. Additionally, consuming foods rich in antioxidants, such as fruits and vegetables, can be beneficial. Foods high in anthocyanins (like blueberries and blackberries) may also support retinal health, but their direct impact on retinal degeneration is still being researched.

3. Commercial Juices and Antioxidants: The purple vegetable juice you mentioned, which contains anthocyanins, can be a good addition to your diet. Anthocyanins are known for their antioxidant properties and may help reduce inflammation and oxidative stress in the body, including the eyes. However, while these juices can be part of a healthy diet, they should not replace a balanced intake of whole foods.

4. Traditional Remedies for Floaters: The suggestion from traditional medicine to reduce soft drink consumption to help with floaters is not scientifically validated. Floaters are typically caused by changes in the vitreous gel of the eye and are not directly influenced by diet. However, maintaining a healthy diet and hydration can support overall eye health. Other methods to manage floaters include staying hydrated, protecting your eyes from UV light, and regular eye check-ups to monitor any changes.

5. Lifestyle Habits and Eye Health: Maintaining good lifestyle habits is indeed beneficial for eye health. This includes getting adequate sleep, managing stress, and taking regular breaks from screens (the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds). A balanced diet rich in vitamins A, C, E, and omega-3 fatty acids can also support retinal health. Regular exercise and avoiding smoking are additional factors that contribute to overall eye health.

In conclusion, while dietary supplements and lifestyle changes can support eye health, they should be part of a comprehensive approach that includes regular eye examinations, especially given your history of myopia and retinal degeneration. If you notice any changes in your vision, such as increased flashes or floaters, please consult your eye care professional promptly. Your eye health is paramount, and proactive management is key to preserving your vision. Thank you for your questions, and I hope this information helps you understand your condition better!
