Post-retinal detachment surgery

Hello, I would like to ask the doctor about my eyes.
I underwent laser treatment for retinal detachment at the beginning of last year, which aimed to seal the detached area.
However, more than a year after the surgery, I still continue to see flashes caused by traction, with almost no signs of reduction.

1.
Considering that I have been seeing these traction flashes for many years prior to the surgery, is it normal for the flashes to not completely disappear?
2.
Is there still a possibility of new detachment occurring in the area that was treated with laser?
3.
I notice that the flashes I see have two different trajectories; what could be the reason for this?

Hello: 1.
The persistence of flashes may be normal, but it could also be a warning sign that requires further evaluation.
Flashes are typically caused by the vitreous pulling on the retina.
After surgery, these flashes should diminish or disappear.
However, if the flashes persist or worsen, it may indicate the presence of other issues.
It is advisable to see an ophthalmologist for an examination as soon as possible, so the doctor can assess your condition and provide appropriate recommendations.
2.
Laser surgery is usually performed to repair retinal detachment and prevent further detachment.
However, in some cases, retinal detachment may occur again, especially if there are other risk factors present in the eye, such as high myopia or other abnormalities in the vitreous.
The risk of recurrent retinal detachment varies from person to person and requires further evaluation by an ophthalmologist.
3.
The different trajectories of flashes may be due to the varying ways in which the vitreous pulls on the retina.
The fibrous structures or abnormalities within the vitreous can produce different visual effects, including varying flash trajectories.

Hello! Thank you for reaching out with your questions regarding your post-retinal detachment surgery symptoms. It’s understandable to have concerns after such a significant procedure, especially when experiencing ongoing visual disturbances like flashes of light. Let’s address your questions one by one.

1. Persistence of Flashes of Light: It is not uncommon for patients to continue experiencing flashes of light after retinal detachment surgery, especially if they had a history of seeing these flashes prior to the surgery. The flashes are often caused by the vitreous gel pulling on the retina, which can happen even after the retina has been reattached. The fact that you have been seeing these flashes for many years prior to your surgery suggests that your vitreous may be more prone to pulling on the retina. In some cases, these flashes can persist for an extended period, and while they may diminish over time, complete resolution is not guaranteed. If the flashes are not accompanied by any new symptoms, such as a sudden increase in floaters or a shadow in your vision, it may be a normal part of your recovery.

2. Risk of New Retinal Detachment: After laser treatment for retinal detachment, there is still a risk of new detachments occurring, especially if there are underlying issues with the retina or vitreous. The laser creates a scar that helps to hold the retina in place, but it does not prevent future detachments entirely. Factors such as high myopia, trauma, or other retinal conditions can increase the risk. It’s essential to maintain regular follow-up appointments with your ophthalmologist to monitor the health of your retina and address any concerns promptly.

3. Different Trajectories of Flashes: The presence of flashes with different trajectories can be attributed to various factors, including the way the vitreous gel interacts with the retina. Different areas of the retina may respond differently to the pulling of the vitreous, leading to flashes that appear to move in different directions. Additionally, the brain processes visual information in complex ways, and sometimes the perception of flashes can vary based on the position of your head or eyes. If you notice any changes in the pattern or intensity of these flashes, it’s important to report these to your eye doctor.

In summary, while it can be concerning to experience persistent flashes after retinal detachment surgery, it is not uncommon. Regular follow-ups with your eye care provider are crucial to ensure that your retina remains healthy and to address any new symptoms that may arise. If you have any further questions or if your symptoms change, don’t hesitate to reach out to your ophthalmologist for personalized advice and care. Your vision health is important, and staying informed is a key part of managing your recovery.
