Questions Related to Post-Retinal Laser Treatment

Dear Dr.
Gao,
Thank you very much for taking the time to answer my questions.
About a year ago, I discovered that I had retinal tears in both my left and right eyes, and both underwent laser treatment.
During my follow-up visit in May of this year, the doctor informed me that the laser treatment on the retina was fine.
However, I forgot to ask the doctor about the following concerns, which I had already been experiencing at the time of the visit:
My main complaint is that recently, when I shift my gaze, my right eye feels fine, but my left eye often has "black lines" appearing.
One line shows up in my field of vision, while another appears at the edge of my vision, which is quite bothersome.
They flash and then disappear, and this only happens when I move my eyes.
In dark places, I do not notice them.
After resting in the dark, when I move my gaze at night, I do not experience this flashing sensation.
However, in bright areas, such as against a white wall or while looking around on the street, the black lines become very noticeable.
They are somewhat better in the morning right after I wake up.
Now, whenever I am in a bright environment, I am constantly distracted and keep noticing the flashing black lines, which makes me fearful of retinal detachment.
Currently, my left eye is -475 and my right eye is -625, with no astigmatism.
In terms of family medical history, my father has undergone surgery for retinal detachment and macular detachment, and he currently has vision in only one eye.
I would like to ask Dr.
Gao:
1.
What could be the cause of these frightening symptoms?
2.
How can I properly protect my eyes in daily life? Should I try to avoid moving my eyes and instead turn my neck?
3.
I love cycling; are there any precautions I should take? I want to protect the vision in my left eye, which has a lower prescription, but I feel helpless and am very afraid of going blind.
I sincerely seek your professional advice.
Thank you very much!

Hello, Yunyun: Usually, seeing flashes of light is primarily caused by the vitreous pulling on the retina, while seeing black lines or floaters is known as floaters syndrome.
This type of pulling is generally harmless, so as long as there is no further retinal damage upon examination, there is no need to worry excessively.
In daily life, just avoid straining your eyes, prevent any impacts, and it's fine to move your eyes around.
Riding a bicycle is also not an issue.
The ophthalmology department at Puzi Hospital in Taiwan is open on Monday, Tuesday, Thursday, and Friday mornings from 8:00 AM to 12:00 PM, and Wednesday afternoons from 2:00 PM to 4:30 PM.
Online responses can only serve as a reference; if necessary, it is still important to seek medical attention at a healthcare facility.
I hope to have the opportunity to serve you.
Dr.
Gao Pilin

Hello! Thank you for reaching out with your concerns regarding your post-laser treatment symptoms related to retinal issues. It's understandable to feel anxious about changes in your vision, especially after experiencing retinal problems in the past. Let’s address your questions one by one.

1. Understanding Your Symptoms: The "black lines" you are seeing, particularly when you move your eyes or change your gaze, could be related to several factors. One possibility is that these are floaters, which are small clumps of gel or cells inside the vitreous (the gel-like substance that fills the eye) that cast shadows on the retina, creating the appearance of lines or spots in your vision. Floaters are common and can become more noticeable in bright environments or against a plain background, such as a white wall. However, since you have a history of retinal issues, it’s crucial to monitor these symptoms closely. If you notice an increase in the number of floaters, flashes of light, or a shadow in your peripheral vision, you should seek immediate medical attention, as these can be signs of retinal detachment.

2. Protecting Your Eyes: To protect your eyes and maintain good vision, consider the following tips:
- Regular Eye Exams: Continue to have regular check-ups with your ophthalmologist to monitor your retinal health, especially given your family history of retinal detachment.

- Eye Rest: If you spend a lot of time looking at screens or reading, practice the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This helps reduce eye strain.

- Lighting: Ensure that you have adequate lighting when reading or working to minimize strain on your eyes.

- Protective Eyewear: When cycling or engaging in outdoor activities, consider wearing sunglasses that block UV rays to protect your eyes from harmful sunlight.

3. Cycling and Eye Health: Cycling is a great form of exercise, but it’s essential to take precautions. Ensure that you wear protective eyewear to shield your eyes from wind, dust, and debris. If you experience discomfort or visual disturbances while cycling, it may be wise to limit your rides until you can discuss these symptoms with your eye doctor.
In summary, while the symptoms you are experiencing can be concerning, they are not uncommon, especially after laser treatment for retinal issues. However, given your family history and previous conditions, it is vital to stay vigilant and maintain open communication with your healthcare provider. If your symptoms worsen or change, do not hesitate to seek immediate medical advice. Your eye health is paramount, and proactive management can help preserve your vision. Thank you for your questions, and I hope this information helps you feel more informed and reassured!
