Eye problems
Hello Doctor: I have had floaters for a long time, and recently when I focus on a screen with one or both eyes, I feel like the objects I'm looking at are moving.
Could this be a sign of macular degeneration? Additionally, I sometimes see flickering in the peripheral vision of my eyes, which is not a brief flash but rather a continuous few seconds of a misty white light flickering.
I am very concerned that this might be a precursor to retinal detachment.
I would appreciate your insights.

Hello, floaters are not related to macular degeneration.
Flashes can also occur in the peripheral vision, and they are not instantaneous but rather consist of a sustained flickering of misty white light for several seconds.
There is a low chance that this is a precursor to retinal detachment, but it is advisable to seek medical evaluation.
Wishing you safety and health.
Sincerely, Dr.
Tsai Wen-Yuan, Director of Ophthalmology, Taoyuan Hospital, Ministry of Health and Welfare.

Hello! Thank you for your inquiry regarding your eye issues, particularly concerning floaters, potential macular degeneration, and retinal concerns. Based on your description, it seems that you are experiencing a combination of symptoms that can be quite concerning, especially given your history of floaters and recent changes in your vision.
Firstly, floaters are common, especially in individuals who are nearsighted or have experienced changes in the vitreous gel of the eye. The vitreous can become more liquid and less gel-like as we age, leading to the perception of floaters. These floaters can appear as small dots, lines, or cobweb-like structures that drift across your field of vision. While they are usually benign, an increase in floaters, especially if accompanied by flashes of light or changes in vision, warrants a thorough examination by an eye care professional.
Regarding your concern about macular degeneration, this condition primarily affects the central part of the retina (the macula) and can lead to vision distortion or loss. The symptoms you describe, such as the sensation of objects moving or the appearance of a "foggy" light in your peripheral vision, could potentially be related to macular issues, but they are not definitive indicators of macular degeneration. Macular degeneration typically presents with symptoms like blurred or distorted central vision, difficulty recognizing faces, or a dark or empty area in the center of vision.
The flashes of light you mentioned, particularly if they are persistent and occur in conjunction with floaters, could indicate a more serious condition, such as retinal detachment or retinal tears. These conditions can occur when the vitreous gel pulls away from the retina, leading to symptoms like flashes of light, an increase in floaters, or a shadow or curtain effect over your vision. It is crucial to seek immediate medical attention if you experience these symptoms, as early detection and treatment can significantly improve outcomes.
In terms of management and improvement of your symptoms, here are some recommendations:
1. Regular Eye Exams: Given your history of floaters and recent changes in vision, it is essential to have regular comprehensive eye exams. Your eye care professional can monitor your eye health, particularly the vitreous and retina, and provide timely interventions if necessary.
2. Protect Your Eyes: If you spend a lot of time in front of screens, ensure you take regular breaks to reduce eye strain. The 20-20-20 rule is helpful: every 20 minutes, look at something 20 feet away for at least 20 seconds.
3. Healthy Lifestyle: Maintaining a healthy diet rich in antioxidants (such as leafy greens, fish, and nuts) can support eye health. Regular exercise and avoiding smoking are also beneficial.
4. Manage Underlying Conditions: If you have conditions like high blood pressure or diabetes, managing these effectively can help reduce the risk of eye complications.
5. Stay Informed: Educate yourself about the symptoms of retinal issues and macular degeneration. Knowing what to look for can help you seek timely care.
In conclusion, while floaters are often benign, the combination of symptoms you are experiencing—especially the flashes of light—should be evaluated by an eye care professional as soon as possible. They can perform necessary tests, such as a dilated fundus examination or optical coherence tomography (OCT), to assess the health of your retina and vitreous. Early detection is key in preventing potential complications, so please do not hesitate to seek medical advice.
