Retinal Holes: Flashes and Floaters Explained

Retinal tears, flashes, and floaters?

Hello, Doctor: I suddenly experienced a cluster of black spots and flashes in my right eye.
After examination, I was diagnosed with floaters and a retinal tear.
I underwent retinal laser photocoagulation at National Cheng Kung University Medical College on July 18 of this year.
Why am I still experiencing flashes two to three days later? Is it possible that the retinal tear has not been fully treated or repaired? Should I return for an immediate follow-up? Is it safe to bend down to wash my face? I appreciate your clarification on these matters.
Thank you.

The occurrence of flashes is related to the retina being pulled.
If the tension is not released, the flashes will persist.
This is not related to whether or not laser treatment is performed, nor is it a sign that a tear has not been properly fixed.
As for bending down to wash your face, there should be no issues!

Hello, thank you for your question. It sounds like you are experiencing some concerning symptoms related to your vision, specifically flashes and floaters, which can indeed be alarming. Given your recent diagnosis of retinal holes and subsequent laser treatment, it’s understandable that you have questions about your ongoing symptoms and what they might mean.

Firstly, it's important to clarify that the presence of flashes and floaters can be common after experiencing a retinal tear or hole, even after treatment. The flashes you are seeing are often caused by the vitreous gel in the eye pulling on the retina, which can happen during the healing process. This is particularly true if the vitreous is still in the process of detaching from the retina, which can lead to ongoing sensations of light or movement in your vision.

Regarding your concern about whether the retinal hole has been completely fixed, it is not uncommon for patients to continue experiencing flashes for some time after laser treatment. The laser works to create a scar around the retinal tear, which helps to seal it and prevent fluid from entering the space between the retina and the underlying tissue. However, the healing process can take time, and the vitreous may still be exerting some traction on the retina, which can lead to the perception of flashes.

As for whether you should return for an immediate check-up, it is always best to err on the side of caution when it comes to eye health. If you notice an increase in the frequency or intensity of the flashes, or if you experience new symptoms such as a sudden increase in floaters, a shadow or curtain over your vision, or any significant changes in your visual acuity, you should contact your eye doctor right away. They may want to perform a thorough examination to ensure that there are no complications from the treatment.

Regarding your question about bending over to wash your face, it is generally advisable to avoid any activities that might put strain on your eyes or increase intraocular pressure, especially in the immediate aftermath of retinal surgery. While low-impact activities like washing your face may not pose a significant risk, it’s always best to follow your surgeon's specific post-operative instructions. If you have any doubts, it would be prudent to consult your eye care provider for personalized advice.

In summary, while it is common to continue experiencing flashes after laser treatment for retinal holes, you should remain vigilant for any new or worsening symptoms. Regular follow-ups with your eye doctor are essential to monitor your condition and ensure proper healing. If you have any concerns or questions about your recovery, do not hesitate to reach out to your healthcare provider for guidance. Your vision is important, and staying proactive about your eye health is key to ensuring the best possible outcomes.
