Post-retinal laser treatment issues?


Hello Doctor: I have myopia of about 700 degrees in both eyes.
Recently, my right eye has been experiencing a small flashing light when I blink.
I visited an ophthalmologist, who advised immediate repair of a hole, so I underwent retinal laser treatment for a small hole in my right eye two weeks ago.
One week after the procedure, I noticed a new light shadow (a vertical line from top to bottom) in my right eye.
It is not visible during the day but is particularly clear in dark places, and I can see it when I blink.
During my follow-up appointment, the doctor re-examined my retina and said there were no issues but could not explain the phenomenon.
Now that it has been two weeks since the laser treatment, I would like to ask: 1.
Will the new light shadow disappear? If it does not disappear, should I be concerned? Why is this happening? 2.
The small point has now turned into a line of light, and I feel that my condition has not improved after the laser treatment.
If I discover a new tear in the future, is it possible for it to heal on its own? 3.
What new symptoms should prompt me to return for a follow-up?

Hello, Xiao Yu:
1.
After undergoing laser treatment, new light flashes may occur, which could be caused by changes in the vitreous body.

2.
If there are no issues with the fundus, these light flashes may gradually subside.
It is advisable to treat any new tears with laser to prevent retinal detachment.

3.
If the light flashes increase in intensity or if there are more floaters, or if you experience darkening or loss of vision, please return for a follow-up as soon as possible.

Taiwan E-Hospital Puzi Hospital Ophthalmology: Monday to Friday, 8:00 AM to 12:00 PM; Wednesday afternoon, 1:00 PM to 4:30 PM.
We hope to have the opportunity to serve you.

More Info


After undergoing retinal laser surgery, it is common for patients to experience a variety of visual changes and concerns. Your situation, where you have noticed a new line of light or shadow after the procedure, is not unusual, and I will address your questions based on the information provided and general medical knowledge regarding post-operative retinal care.

1. Will the new light shadow disappear? Should I be concerned?
The appearance of new light phenomena, such as a line or shadow, can be attributed to several factors. After laser surgery, the retina undergoes changes as it heals, which can lead to temporary visual disturbances. These disturbances may include flashes of light, floaters, or shadows. In many cases, these symptoms can diminish over time as the retina stabilizes and heals. However, if the light shadow persists, it is essential to monitor it closely. While it may not indicate a serious problem, any new or worsening visual symptoms should be reported to your ophthalmologist. They can perform a thorough examination to ensure that there are no complications, such as a new retinal tear or detachment.

2. Can a new tear heal on its own?
Retinal tears do not typically heal on their own. If a new tear develops, it is crucial to seek immediate medical attention. While some small tears may not lead to significant issues, they can progress to retinal detachment if not treated promptly. Laser treatment or cryotherapy is often necessary to seal the tear and prevent further complications. If you notice any sudden changes in your vision, such as an increase in floaters, flashes of light, or a shadow in your peripheral vision, you should return to your eye doctor as soon as possible.

3. When should I return for a follow-up?
It is essential to maintain regular follow-up appointments with your ophthalmologist after retinal surgery. You should return for a check-up if you experience any of the following:
- Sudden changes in vision, such as blurriness or loss of vision.

- An increase in the number of floaters or flashes of light.

- Any new shadows or curtain-like effects in your vision.

- Persistent discomfort or pain in the eye.

In addition to these specific symptoms, it is advisable to adhere to the follow-up schedule recommended by your surgeon. Regular monitoring is crucial to ensure that your retina is healing properly and to catch any potential issues early.

Additional Considerations:
Post-operative care is vital for optimal recovery. Here are some general recommendations:
- Avoid strenuous activities: Activities that involve heavy lifting, straining, or high-impact sports should be avoided for a period as advised by your doctor.

- Protect your eyes: Wearing sunglasses outdoors can help reduce glare and protect your eyes from harmful UV rays.

- Monitor your symptoms: Keep a journal of any visual changes or symptoms you experience, as this can help your doctor assess your condition more effectively during follow-up visits.

In conclusion, while experiencing new visual phenomena after retinal laser surgery can be concerning, it is often part of the healing process. However, vigilance is essential, and any persistent or worsening symptoms should prompt a visit to your eye care professional. Regular follow-up and open communication with your ophthalmologist will help ensure the best possible outcome for your vision.
