Flashes of light in the eyes?

Dear Dr.
He,
My left eye experienced flashes and an increase in floaters in December of last year.
After an examination at an ophthalmology clinic, both eyes were found to have retinal tears.
At that time, I underwent laser treatment on my left eye.
The following week, I went to a larger hospital for a check-up and received laser treatment on my right eye, but since there was still a tear in my left eye, I underwent another laser procedure on the left eye a few days later.

More than two months later, I noticed small flashes in the dark in my left eye, and upon returning to the hospital for an examination, a small tear was found again, leading to another laser surgery that same day.
After the third laser surgery, I felt that my recovery was not as good as after the first two procedures; I experienced severe dry eye, and the color in my visual center appeared slightly yellow, with some distortion in straight lines.
Therefore, I sought a second opinion at another hospital, where I was diagnosed with macular folds and tears, and my left eye's vision was 0.4.

At the end of March, I underwent surgery for the macula.
The recovery was good, and two months later, my left eye's vision improved to 0.8.
However, in the past few weeks, I have been experiencing pulling flashes in my left eye.
I informed my doctor during my follow-up visit, and he said it would gradually improve.
I am still somewhat concerned about the possibility of new tears developing, especially since my next follow-up appointment is in two and a half months, and I am worried about the condition of my eye during this period.
The recent flashes have not been accompanied by floaters.
Question 1: Are these flashes a part of the recovery process after surgery?
Question 2: Should I return for a follow-up examination to confirm the condition of my eye?
Question 3: Could multiple laser treatments on the same eye have adverse effects?
Thank you.

Hello Miss Liao: 1.
Flashes are often caused by traction on the retina, usually indicating that there are still areas of residual tension on the retina.
2.
If the frequency of flashes significantly increases, or if accompanied by floaters, it is recommended to return for a dilated eye examination.
3.
Since these are typically very peripheral lasers, the impact is generally minimal.

More Info

Hello! Thank you for your detailed inquiry regarding your eye condition and the flashing lights you are experiencing post-surgery. It’s understandable to feel concerned, especially after undergoing multiple procedures. Let’s address your questions one by one while providing some additional context about the situation.

1. Are the flashes a part of the recovery process?
Flashing lights in the eye, particularly after surgeries like laser treatment for retinal tears, can indeed be a part of the recovery process. These flashes often occur due to the vitreous gel in the eye pulling on the retina, which can happen as the eye heals. This phenomenon is known as "posterior vitreous detachment" and is relatively common after retinal surgery. However, it’s crucial to monitor these symptoms closely. If the flashes become more frequent or are accompanied by new floaters or a shadow in your vision, it’s essential to seek immediate medical attention, as these could indicate a new retinal tear or detachment.

2. Should you return for a follow-up examination?
Given your history of retinal issues and multiple surgeries, it would be prudent to schedule a follow-up appointment sooner rather than later, especially if you notice any changes in your symptoms. Regular monitoring is key in the post-operative period to ensure that any potential complications are caught early. If you feel anxious about the waiting period until your next scheduled appointment, don’t hesitate to reach out to your eye care provider for advice or to see if an earlier visit is possible.

3. Are there any adverse effects from multiple laser treatments on the same eye?
Multiple laser treatments can lead to some complications, but they are generally safe when performed by an experienced ophthalmologist. However, repeated procedures may increase the risk of scarring or changes in the retinal structure, which could potentially affect your vision. It’s essential to maintain open communication with your eye doctor about your concerns and any symptoms you experience. They can provide tailored advice based on your specific situation and the condition of your eye.

Additional Considerations:
- Dry Eye Symptoms: You mentioned experiencing severe dry eye, which can be a common side effect after eye surgeries. Managing dry eye is crucial, as it can affect your overall comfort and vision. Consider using artificial tears or other treatments recommended by your eye doctor to alleviate these symptoms.

- Color Changes and Visual Distortions: The yellowish tint and distorted lines you are noticing could be related to the changes in the retina or the effects of the surgeries. These symptoms should be discussed with your ophthalmologist, who may suggest further evaluation or treatment options.

- Psychological Impact: It’s also worth noting that dealing with ongoing eye issues can be emotionally taxing. If you find yourself feeling anxious or overwhelmed, consider seeking support from a mental health professional or joining a support group for individuals with similar experiences.

In conclusion, while some flashing lights can be a normal part of the healing process, it’s essential to remain vigilant and proactive about your eye health. Regular check-ups and open communication with your healthcare provider will help ensure the best possible outcome for your vision. Wishing you a smooth recovery and improved eye health!
