Retinal Issues: Questions After Eye Trauma and Laser Treatment - Ophthalmology

Retinal issues?


Hello, Dr.
Tsai! Recently, my eye suffered an injury (impact), and afterward, I started seeing flashes of light in my peripheral vision that seem to move (sometimes from top to bottom, and sometimes from bottom to top).
I went to an ophthalmology clinic where the doctor dilated my pupils for a fundus examination.
The result showed that my retina was fine, but the next day, the flashes became more frequent.
I then went to another large hospital for a re-examination, and the doctor said my retina was thin and close to tearing.
I was asked if I wanted laser treatment, and I agreed immediately (because I was very worried about retinal detachment).
I have some questions I would like to ask:
1.
The doctor said my retina is thin and close to tearing; is laser treatment absolutely necessary? (I have read online that a thin retina does not always require laser treatment.) Could it cause more harm if I undergo laser treatment before it actually tears?
2.
After the laser treatment, I still see flashes of light moving for two to three days (the frequency has decreased); is this normal, or does it mean the laser treatment was not effective?
3.
After undergoing laser treatment, does the risk of retinal detachment become very low? Or is there still a significant chance that detachment could occur?
4.
How long does the effect of retinal laser treatment last? If detachment does occur later, can I undergo laser treatment again, or will surgery be necessary?
5.
After the laser treatment, what should I pay attention to in my daily life? Can I continue working on the computer?
6.
Will my symptoms increase the likelihood of blindness in the future?
Thank you, Dr.
Tsai, for your patience in reading and answering my questions.
I wish you good health!

Hello! Thank you for your detailed questions regarding your recent eye trauma and subsequent treatment. It’s understandable to have concerns after experiencing such an event, especially when it involves the retina and potential vision loss. Let’s address your questions one by one.

1. Is laser treatment necessary for a thin retina?
When a retina is described as "thin" or "stretched," it indicates a risk for retinal tears or detachment. While not every case of a thin retina requires laser treatment, it is often recommended as a preventive measure, especially if there are symptoms like flashes of light or floaters. The rationale behind this is to create a barrier that helps to secure the retina to the underlying tissue, thereby reducing the risk of detachment. If your doctor recommended laser treatment, it was likely based on their assessment of your specific condition and the risks involved. However, if you have doubts, seeking a second opinion from another retinal specialist can provide additional clarity.

2. Is it normal to still see flashes after laser treatment?
Experiencing flashes or floaters after laser treatment can be normal, especially in the days immediately following the procedure. The laser creates small burns in the retina, which can temporarily irritate the surrounding tissue, leading to continued visual disturbances. However, if the frequency or intensity of these flashes increases significantly, or if you notice new symptoms, it’s important to follow up with your eye care provider to ensure that everything is healing as expected.

3. Does laser treatment significantly reduce the risk of retinal detachment?
Laser treatment is effective in reducing the risk of retinal detachment in cases where the retina is at risk due to thinning or other factors. While it does not eliminate the risk entirely, it significantly lowers it. The long-term success of the treatment can vary based on individual circumstances, including the extent of the initial damage and the overall health of the retina.

4. How long does the effect of laser treatment last, and can it be repeated?
The effects of laser treatment can last for many years, but this can vary. Some patients may require additional treatments if new areas of concern develop. If a retinal detachment occurs despite previous laser treatment, surgical intervention may be necessary. The type of surgery would depend on the specifics of the detachment.

5. What precautions should be taken after laser treatment?
After laser treatment, it is generally advised to avoid strenuous activities, heavy lifting, or any activities that could strain your eyes for a short period. You can usually return to normal activities, including computer work, but it’s wise to take regular breaks to reduce eye strain. Follow your doctor’s specific recommendations regarding activity restrictions.

6. Does this condition increase the risk of future vision loss?
While experiencing flashes and having a thin retina can indicate a higher risk for complications, timely treatment, such as laser therapy, can significantly mitigate this risk. Regular follow-ups with your eye care provider are essential to monitor your condition and address any new symptoms promptly.

In conclusion, it’s crucial to maintain open communication with your eye care team. If you have ongoing concerns or if your symptoms change, do not hesitate to reach out to them. Regular monitoring and adherence to treatment plans are key to preserving your vision and preventing complications. Wishing you a smooth recovery and the best of health!
