Retinal Laser Treatment: Concerns and Clarifications - Ophthalmology

Retinal laser therapy


Hello, Doctor.
I am the person who previously inquired about having undergone laser treatment at another clinic, but no holes or laser marks were found during the examination.
Recently, I went to another ophthalmology clinic, and again, no holes or laser marks were detected.
However, they did find some dark pigmentation in the upper part of my right eye.
The doctor mentioned that it could be congenital.
Could this dark spot possibly be a result of laser treatment? Is it easy to differentiate between laser marks and pigmentation? Since the laser treatment was done a while ago, is it possible that the laser marks and holes could have faded over time and become undetectable? Additionally, I have seen many videos of retinal laser treatments that show green light, but I don't recall seeing any green light during my procedure.
Is it typical for this type of laser to have green light? I also found online that lasers can cause macular folds; is that true? I felt something was off with the doctor at that time, and the Google reviews were not very good.
To be honest, I really hope that the doctor did nothing at that time.
I am genuinely worried that my eyes were subjected to unnecessary laser treatment or some other harm.
Thank you, Doctor.
I appreciate your help.

Hello, the distinction between laser marks and melanin can sometimes be challenging.
However, the type of laser should be identifiable.
Different lasers may not necessarily emit green light.
Peripheral lasers should not cause macular folds.

Hello! Thank you for your questions regarding retinal laser treatment and your concerns about potential complications. It’s understandable to feel anxious about your eye health, especially after undergoing procedures that can significantly impact vision.

Firstly, regarding the dark pigmentation you mentioned in your right eye, it is essential to clarify that such pigmentation can occur naturally and may not necessarily be a result of previous laser treatments. The presence of dark spots or pigmentation in the retina can be due to various factors, including congenital conditions, age-related changes, or even previous trauma. In your case, since multiple examinations have not revealed any signs of retinal holes or laser marks, it is likely that this pigmentation is benign and not related to any past laser procedures.

As for differentiating between laser marks and natural pigmentation, trained ophthalmologists can typically distinguish between the two based on their appearance and location. Laser treatment often leaves specific patterns or changes in the retinal structure, while natural pigmentation tends to have a more uniform appearance. If you have concerns about the nature of the pigmentation, a second opinion from a reputable retinal specialist may provide additional reassurance.

Regarding your question about whether laser marks or holes can disappear over time, it is unlikely that any significant changes would occur after a long period. Once a laser treatment is performed, the effects are generally permanent. However, the absence of visible signs of treatment does not necessarily indicate that no procedure was performed; it could also mean that the treatment was effective and did not leave any lasting marks.
Concerning the green light you expected to see during the laser treatment, it is important to note that different types of lasers emit various wavelengths of light. While many retinal lasers do emit a green light, some may use other colors depending on the specific technology and purpose of the treatment. If you did not see a green light, it does not automatically imply that the procedure was not performed; it may simply be a characteristic of the laser used.

Lastly, regarding the concern about laser treatment causing macular folds or other complications, it is true that any surgical procedure carries risks. However, reputable laser treatments are designed to minimize such risks. Macular folds can occur due to various reasons, including trauma or underlying retinal conditions, but they are not a common outcome of laser treatment when performed correctly. If you have ongoing concerns about your vision or the health of your retina, it is crucial to maintain regular follow-ups with your eye care provider.

In summary, while it is natural to have concerns about your eye health, the information you provided suggests that your current findings may not be related to previous laser treatments. If you continue to feel uneasy, seeking a second opinion from a trusted ophthalmologist can provide peace of mind and clarity regarding your eye condition. Remember, your vision is invaluable, and staying proactive about your eye health is essential. Thank you for reaching out, and I hope this information helps alleviate some of your concerns!
