Post-Laser Retinal Issues: Addressing Floaters and Concerns - Ophthalmology

Issues related to retinal laser treatment?


Hello Dr.
Tsai, I previously inquired about the issue of floaters that developed after retinal laser treatment (seeing the sky filled with very large floaters throughout my vision).
I have consulted many doctors regarding this issue, and they all said it is unrelated to the laser treatment.
However, I clearly developed two very large dark shadows the day after the procedure, and within a week, my entire vision was filled with them.
I believe I have a high tolerance for discomfort, but while riding my bike, nearly one-third of my field of vision is filled with floating dark shadows, and there are numerous black dots, lines, circles, and bubbles in other areas.
These past days have been extremely painful for me.
I truly don’t understand why the doctor initially told me my eyes were in serious condition and that I needed immediate laser treatment, while many other hospitals later informed me that it could simply be monitored, especially since there was no hole—just one area that was thinner.
I am not looking to assign blame; I just want to understand what is happening with my eyes, given the countless dark shadows.
Thank you, Dr.
Tsai, for your patience in reading this.
I hope you can provide some advice on what might be happening with my eyes.
Thank you very much.

Hello! Thank you for sharing your concerns regarding the post-laser retinal issues you are experiencing, particularly the significant increase in floaters and visual disturbances. I understand how distressing this situation can be, especially when it affects your daily life and activities like riding a bike.

Firstly, it's important to clarify that the presence of floaters, which are often described as spots, lines, or cobweb-like structures in your vision, can be a common occurrence, especially after undergoing laser treatment for retinal issues. Floaters are typically caused by changes in the vitreous gel that fills the eye, which can become more pronounced with age or due to certain eye conditions. In your case, the laser treatment may have triggered or exacerbated these changes, leading to the sudden appearance of large floaters.

The fact that you noticed these floaters immediately after the laser procedure raises some questions. While many doctors may assert that the laser treatment itself is not directly responsible for the increase in floaters, it is possible that the treatment could have caused some temporary changes in the vitreous or the retina that made existing floaters more noticeable. The laser may have also altered the structural integrity of the vitreous, leading to a higher likelihood of floaters becoming more prominent.

Regarding your experience of seeing large black shadows and a multitude of floaters, it is crucial to monitor these symptoms closely. While floaters are generally benign, a sudden increase in their number, especially if accompanied by flashes of light or a curtain-like shadow over your vision, can indicate a more serious condition, such as retinal detachment. It is essential to seek immediate medical attention if you experience these symptoms, as they may require urgent intervention.

In terms of your ongoing discomfort and the significant impact on your quality of life, it is advisable to continue consulting with eye care professionals. If you feel that your concerns are not being adequately addressed, seeking a second or even third opinion from a retinal specialist may provide you with more clarity and reassurance. These specialists can perform detailed examinations, including optical coherence tomography (OCT) and other imaging techniques, to assess the condition of your retina and vitreous more thoroughly.

As for your question about the necessity of the laser treatment, it is understandable to feel frustrated if you believe that the procedure was not warranted. However, the decision to proceed with laser treatment is often based on the assessment of potential risks versus benefits. In some cases, doctors may recommend laser treatment to prevent further complications, even if the immediate risks seem minimal. It is essential to have open discussions with your healthcare providers about your treatment options and any concerns you may have.

In the meantime, here are some general recommendations for managing your symptoms:
1. Regular Eye Exams: Continue to have regular check-ups with your eye doctor to monitor your condition and any changes in your vision.

2. Visual Hygiene: Reduce eye strain by taking breaks during activities that require prolonged focus, such as reading or using screens.

3. Stay Informed: Educate yourself about floaters and retinal health, but also be cautious not to self-diagnose. Rely on professional advice for any changes in your symptoms.

4. Report New Symptoms: If you notice any new symptoms, such as flashes of light, significant changes in vision, or a sudden increase in floaters, seek medical attention promptly.

5. Emotional Support: Dealing with visual disturbances can be stressful. Consider speaking with a counselor or support group to help manage any anxiety related to your vision.

In conclusion, while floaters can be a common and often benign issue, your experience following laser treatment warrants careful monitoring and possibly further evaluation. Don't hesitate to advocate for your health and seek the answers you need to feel more secure about your vision. Thank you for sharing your story, and I hope you find relief and clarity soon!
