Are there any side effects from preventive laser surgery?

Hello Doctor! Three days ago in the afternoon, I underwent a scatter laser examination, and the doctor recommended that I need to have a preventive focal retinal laser surgery because the retina in the lower part of my right eye is very thin and may soon tear.
After the procedure, I actually feel fine, but that evening when I got home, I noticed that whenever I look slightly downward, I can see a dark spot in my upper field of vision.
When I look upward, I cannot see the dark spot; it only appears when I look down.
This is especially noticeable in dark environments at night.
Is this a normal phenomenon? Should I schedule an earlier follow-up appointment? I am due for a follow-up in two weeks, and I don't want to overreact by going in early.
Also, can I fly before my follow-up appointment? My doctor mentioned it was okay, but now with this symptom, I am feeling uneasy and wanted to check.
Thank you.

Hello: Based on your description, you have experienced some new symptoms after undergoing localized retinal laser surgery.
Here are my recommendations:
1.
Black spots phenomenon: The sensation of having black spots in your line of sight after surgery may be normal, especially during the adaptation period post-surgery.
Localized retinal laser surgery can lead to changes in vision, but these symptoms typically improve on their own over time.
2.
Follow-up appointment: If your doctor has advised you to return for a follow-up in two weeks, and you currently have no other discomfort aside from the described black spots, you may choose to keep the original appointment.
However, if this symptom worsens, affects your vision, or causes other discomfort, it is best to schedule an earlier visit.
3.
Flying: If your doctor has informed you that it is safe to fly and your current symptoms are considered normal, you may consider flying.
If you have any concerns, it would be prudent to have your attending physician check your condition first.

More Info

Preventive laser surgery for the retina, often referred to as laser photocoagulation, is a common procedure used to treat conditions such as retinal tears or thinning. While it can be effective in preventing more serious complications like retinal detachment, it is important to understand the potential side effects and what to expect post-surgery.

Side Effects of Preventive Laser Surgery
1. Visual Disturbances: One of the most common side effects after laser treatment is the perception of visual disturbances. Patients may experience temporary changes in vision, such as seeing spots, flashes of light, or even shadows. The phenomenon you described—seeing a dark spot when looking down—could be related to the laser treatment. This may be due to the formation of scar tissue or changes in the retinal structure following the procedure. These symptoms can often resolve over time, but it is crucial to monitor them.

2. Scarring: The laser creates small burns on the retina to promote healing and prevent further damage. While this is generally a controlled process, it can lead to scarring, which may affect vision. In some cases, the scar tissue can pull on the retina, leading to further complications.

3. Increased Floaters: Some patients report an increase in floaters after laser surgery. Floaters are small specks or strands that drift through your field of vision, and while they are often harmless, an increase can be concerning.

4. Changes in Peripheral Vision: There may be temporary or, in rare cases, permanent changes in peripheral vision. This is something to discuss with your ophthalmologist if you notice any significant changes.

5. Risk of Retinal Detachment: Although the procedure aims to prevent retinal detachment, there is a small risk that it could inadvertently contribute to this condition, especially if there are pre-existing vulnerabilities in the retina.

Recommendations
Given your recent experience of seeing a dark spot when looking down, it is advisable to contact your ophthalmologist. While some visual disturbances can be normal after laser surgery, any new or worsening symptoms should be evaluated to rule out complications. It’s better to err on the side of caution, especially with retinal issues.

As for flying, many ophthalmologists may allow patients to travel shortly after laser surgery, provided there are no significant complications. However, since you are experiencing new symptoms, it would be prudent to discuss this with your doctor before making any travel plans. They can provide personalized advice based on your specific situation and the nature of your symptoms.

Conclusion
Preventive laser surgery for the retina is generally safe and effective, but like any medical procedure, it carries risks and potential side effects. Monitoring your symptoms and maintaining open communication with your healthcare provider is essential. If you notice any changes in your vision or have concerns about your recovery, do not hesitate to reach out to your ophthalmologist for guidance. They can provide the best advice tailored to your condition and help ensure your eyes remain healthy.
