Floaters and retinal issues?

Hello, Doctor Gao.
I would like to ask why, when I turn my eyes to the extreme left and right in the dark, I see a flash of light.
Is this a normal phenomenon, or could it indicate a problem with my retina? I had an indirect ophthalmoscopy last month, and the doctor said my retina was fine, but I forgot to mention this situation to him at that time.
Should I go for another examination?
Additionally, I have developed floaters due to eye strain, but most of them are very faint, like dust, and the darker spots do not remain in my field of vision.
If I take good care of my eyes, will the floaters improve?

Hello, Student Liao: When your eyes turn to the extreme left or right, you may experience flashes, which indicate that the vitreous is pulling on the retina due to pressure.
While this is a normal phenomenon, it is advisable to avoid such extreme eye movements, as they can be harmful.
The doctor has confirmed that your retina is fine, and follow-up visits may not be necessary.
Floaters are harmless and are a normal occurrence; there is no way to prevent them, and they are not caused by excessive eye strain.
Sometimes, floaters may become less noticeable over time, but they can also increase in number; the best approach is to coexist with them peacefully.
The Ophthalmology Department at Puzi Hospital in Taiwan operates on the following schedule: Monday, Tuesday, Thursday, and Friday from 8:00 AM to 12:00 PM, and Wednesday from 2:00 PM to 4:30 PM.
Online responses should only be used as a reference; if necessary, you should seek care at a medical facility.
I hope to have the opportunity to serve you.
Best regards, Gao Pilin.

Hello! Thank you for your questions regarding your eye health, particularly concerning floaters and potential retinal issues. Let's address your concerns one by one.

1. Flashes of Light When Moving Your Eyes: The phenomenon you describe, where you see flashes of light when moving your eyes to the extreme sides, can be related to a few factors. In many cases, these flashes are caused by the vitreous gel inside the eye pulling on the retina, which can happen as we age or due to other factors. This is often referred to as "photopsia." Since you mentioned that you had a recent indirect ophthalmoscopy and your retina was deemed healthy, this is a reassuring sign. However, it’s always a good idea to communicate any new symptoms to your eye care provider. If these flashes are persistent or accompanied by other symptoms like a sudden increase in floaters, a shadow in your vision, or a decrease in vision, you should seek immediate medical attention as these could indicate retinal tears or detachment.

2. Floaters and Eye Care: Regarding your floaters, it’s common for people to experience them, especially if they have a history of eye strain or myopia (nearsightedness). Floaters can appear as small specks, cobwebs, or shadows in your vision, and they can be more noticeable against bright backgrounds. While floaters are generally harmless, they can be bothersome. Good eye care practices can help maintain overall eye health, but they may not necessarily eliminate floaters. Staying hydrated, taking regular breaks during prolonged screen time, and ensuring proper lighting while reading or working can help reduce eye strain, which may indirectly lessen the perception of floaters. If you notice any changes in the frequency or appearance of your floaters, or if they become more pronounced, it’s advisable to consult with your eye doctor.

In summary, while the flashes of light you experience may not be a cause for immediate concern, it’s crucial to keep your eye care provider informed about any new or changing symptoms. Regular eye exams are essential, especially if you have existing conditions like floaters or if you experience any new visual disturbances. Maintaining good eye health through proper care and regular check-ups can help you manage your symptoms effectively. If you have further concerns or if your symptoms worsen, do not hesitate to reach out to your healthcare provider for a thorough evaluation. Your eye health is paramount, and staying proactive about it is the best approach.
