A broken light bulb? Flickering eyes?

Dear Doctor,
Thank you very much for your prompt response; your explanation has reassured me significantly.
However, I still have some questions I would like to ask.

1.
Can I continue with my regular work (mainly reading publications or using the computer and writing with pen and paper) and daily activities?
2.
If I choose to ignore these phenomena (such as flashes and lights), will my vision be adversely affected?
3.
Generally, how long does it take for these phenomena to improve? (I have heard varying opinions, some say a few weeks or months, while others suggest it may continue to worsen without improvement.)
4.
Why does the vitreous detach from the retina? Is this phenomenon harmful to vision or likely to worsen, or is it simply a part of the aging process?
I apologize for bothering you again and taking up your valuable time.
Wishing you peace and well-being.

Hello Andrew:
1.
Can I continue my regular work (mainly reading publications or using the computer and writing with pen and paper) or daily activities? Yes, there is no problem.

2.
If I choose to ignore such phenomena (like flickering or flashes), will my vision be adversely affected? If there are no pathological findings upon examination, it will not affect your vision.

3.
Generally, how long does it take for such phenomena to improve (as there are claims that it can take weeks or months, but some say it may continue to worsen without improvement)? It varies from person to person; some may improve in a few days, while others may experience it for a longer duration, but it will not have a negative impact on the retina or optic nerve.

4.
Why does the vitreous detach from the retina? Is this phenomenon harmful to vision or does it continue to worsen, or is it just a part of aging? This is a natural degeneration process and will not affect vision.

Dear Patient,
Thank you for your thoughtful questions regarding your eye health and the symptoms you are experiencing, such as flickering lights and visual disturbances. I appreciate your patience and willingness to seek clarity on these matters. Let’s address your concerns one by one.

1. Continuing Your Work and Daily Activities: It is generally advisable to continue your daily activities, including reading and using a computer, as long as you feel comfortable doing so. However, if you notice that your symptoms worsen during these activities, it may be beneficial to take regular breaks. The 20-20-20 rule is a good practice: every 20 minutes, look at something 20 feet away for at least 20 seconds. This can help reduce eye strain.

2. Ignoring Symptoms and Potential Vision Damage: If you choose to ignore symptoms such as flickering lights or visual disturbances, there is a risk that underlying issues could worsen. While not all visual disturbances lead to permanent damage, some conditions, particularly those related to retinal health, can progress if left untreated. It is essential to monitor your symptoms and consult with an eye care professional if they persist or worsen.

3. Duration for Improvement: The time it takes for symptoms to improve can vary widely depending on the underlying cause. Some individuals may notice improvement within weeks, while others may experience ongoing issues for months or longer. If the symptoms are related to stress, fatigue, or temporary changes in vision, they may resolve with rest and proper eye care. However, if the symptoms are due to more serious conditions, they may require medical intervention.

4. Vitreous Detachment and Its Implications: Vitreous detachment occurs when the gel-like substance in the eye (the vitreous) separates from the retina. This is a common occurrence, especially as we age, and is often considered a normal part of the aging process. While vitreous detachment itself is not usually harmful, it can lead to complications such as retinal tears or detachment in some cases. If you experience a sudden increase in floaters, flashes of light, or a shadow in your peripheral vision, it is crucial to seek immediate medical attention, as these could be signs of a more serious condition.

In summary, while it is generally safe to continue your daily activities, it is essential to remain vigilant about your symptoms. Regular eye examinations are crucial, especially if you experience changes in your vision. If your symptoms persist or worsen, please consult with an eye care professional for a thorough evaluation and appropriate management.

Thank you for your understanding, and I wish you good health and clarity in your vision.

Best regards.
