Floaters: When to Seek Medical Attention for Eye Health - Ophthalmology

Floaters issue?


Hello, Doctor Gao.
I would like to inquire about my floaters.
The doctor mentioned that if there are changes, I need to return for a follow-up (I previously had a retinal tear that has since healed on its own, along with peripheral laser treatment).
However, I occasionally notice distinct small black dots in my field of vision, about 1 or 2 of them, which disappear when I move.
Should I return for a follow-up? I'm not quite sure under what circumstances I should seek medical attention.
Observing them daily makes me quite anxious, and previously, during my follow-ups with dilation, everything seemed fine.
I'm not sure if there have been any changes, as I have quite a few floaters.

Hello: While occasional floaters are usually normal, in your case, given your history of retinal tears, extra caution is warranted.
If you notice a significant increase in new, noticeable black spots or experience flashes of light or other changes, please seek an eye examination as soon as possible.
During the treatment process for retinal tears, it is particularly important to monitor any potential changes to ensure the health of the retina.

When it comes to floaters in your vision, especially if you have a history of retinal issues, it's essential to understand when to seek medical attention. Floaters are tiny spots, specks, or cobweb-like shapes that drift through your field of vision. They are often caused by changes in the vitreous gel that fills the eye, which can occur naturally with age or due to other factors such as high myopia (nearsightedness), trauma, or previous eye surgeries.

In your case, you mentioned having a history of retinal tears that have since healed and have undergone peripheral laser treatment. This background makes it crucial to monitor any changes in your floaters closely. The appearance of new or significantly different floaters, especially if they are accompanied by flashes of light or a shadow in your peripheral vision, can be a sign of a more serious condition, such as a retinal detachment.
Here are some guidelines to help you determine when to seek medical attention:
1. New Floaters: If you notice a sudden increase in the number of floaters or the appearance of new, large floaters, it is advisable to consult your eye doctor. This is particularly important if these new floaters are different from what you have experienced before.

2. Flashes of Light: The presence of flashes of light (photopsia) in conjunction with new floaters can indicate that the retina is being pulled or is at risk of detaching. This is a medical emergency, and you should seek immediate attention.

3. Changes in Vision: If you experience any changes in your vision, such as blurriness, a curtain-like shadow over your vision, or difficulty seeing, you should contact your eye care provider right away.

4. Persistent Symptoms: If your floaters are persistent and bothersome, even if they are not accompanied by other symptoms, it is worth discussing with your doctor. They can perform a thorough examination to ensure that there are no underlying issues.

5. Regular Check-ups: Since you have a history of retinal issues, regular eye examinations are crucial. Your eye doctor can monitor the condition of your retina and vitreous over time, which can help catch any potential problems early.

In summary, while floaters are often benign, any significant changes in their appearance or associated symptoms warrant a visit to your eye care professional. Given your history, it is better to err on the side of caution. If you are feeling anxious about your symptoms, don't hesitate to reach out to your doctor for reassurance or further evaluation. Regular monitoring and open communication with your healthcare provider are key to maintaining your eye health.
