Symptoms caused by vitreous traction on the retina?


Thank you very much, Dr.
Gao, for your patient response! It seems that every day after the laser treatment has some slight changes, but it's difficult to gauge to what extent I should return for a follow-up...
Therefore, I would like to ask again...
Regarding the previous question, I have noticed in the past few days after the laser treatment that sometimes after blinking, there is a flickering area in the lower part of my vision that disappears quickly (similar to the flickering when a fluorescent light is first turned on).
Is this a symptom of floaters? Does it indicate that the floaters are worsening? You mentioned that this is a symptom of vitreous traction on the retina, which is a type of change in the vitreous, and such phenomena can occur after laser surgery.

Q1.
Is the "symptom of vitreous traction on the retina" similar to floaters in that it is unlikely to disappear, or should it gradually resolve if it is a result of the laser surgery? (I have noticed that the frequency of these occurrences has significantly increased over the past two days, and I have even seen flashes two or three times, all in the same area of my lower vision.
However, today is slightly better than yesterday.)
Q2.
To what extent should I be concerned about the flickering or wavy phenomena in the lower part of my vision before seeking medical examination? (Is it based on increasing frequency? Expanding area? Changes in color?)
Q3.
Is it harmful to my eyes to have undergone three to four dilated eye examinations within two weeks?
Thank you for your assistance in clarifying these concerns and providing advice.
I greatly appreciate it.
Wishing you good health and well-being!

Hello Winnie,
Q1.
"The symptoms caused by the vitreous pulling on the retina," are these similar to floaters in that they are unlikely to disappear? When the vitreous no longer pulls on the retina, the symptoms will resolve.
This indicates that the vitreous has detached from the retina in that area.
Q2.
Regarding the appearance of flickering or wavy patterns in the lower visual field, at what point should one consider returning for a medical examination? Since there are no holes in your retina, these changes should be temporary, related to posterior vitreous detachment.
It is advisable to wait for your scheduled follow-up appointment with the doctor.
However, if there are significant changes in vision, visual field loss, or a substantial increase in floaters, immediate medical attention is necessary.
Q3.
Is it harmful to have undergone dilated eye examinations three to four times within two weeks? ...
No, it is not harmful.
Taiwan E-Hospital Puzi Hospital Ophthalmology: Monday, Tuesday, Thursday, and Friday from 8:00 AM to 12:00 PM; Wednesday from 2:00 PM to 4:30 PM.
Online responses are for reference only; it is essential to seek medical care at a healthcare facility when necessary.
I hope to have the opportunity to assist you.

Thank you for your detailed questions regarding your symptoms following laser treatment and the potential implications of vitreous detachment. Understanding these symptoms is crucial for managing your eye health effectively.

Q1: Regarding the symptoms of vitreous traction on the retina, are they similar to floaters and are they likely to persist?
Vitreous traction can indeed produce symptoms similar to floaters, including flashes of light or shimmering effects in your vision. These symptoms occur when the vitreous gel, which fills the eye, pulls on the retina. After laser treatment, it is not uncommon for patients to experience transient visual disturbances as the eye adjusts. While some symptoms may diminish over time, others can persist, especially if there is ongoing traction. If the flashes are increasing in frequency or intensity, it may indicate that the vitreous is continuing to pull on the retina, which could potentially lead to more serious complications, such as retinal tears or detachment. Therefore, while some changes may resolve, it is essential to monitor your symptoms closely.

Q2: When should you seek further medical evaluation for these symptoms?
You should consider returning for a follow-up examination if you notice any of the following changes:
- An increase in the frequency of flashes or floaters.

- A significant change in the pattern or area of visual disturbances.

- The appearance of new symptoms, such as a shadow or curtain effect in your vision.

- Any sudden changes in your overall vision, such as blurriness or loss of vision.

If the flashes become more pronounced or if you experience any new visual phenomena, it is advisable to consult your eye care provider promptly. Regular monitoring is crucial, especially after laser treatment, as early detection of complications can significantly improve outcomes.

Q3: Is frequent dilation harmful to the eyes?
Having multiple dilated eye exams within a short period is generally safe and should not cause harm to your eyes. Dilation allows for a thorough examination of the retina and vitreous, which is essential for diagnosing potential issues. However, it can temporarily affect your vision and sensitivity to light. If you have concerns about the frequency of these exams, discuss them with your eye care provider, who can provide personalized advice based on your specific situation.

In summary, while some symptoms following vitreous detachment and laser treatment may be benign and self-limiting, it is essential to remain vigilant. Regular follow-ups and open communication with your eye care provider will help ensure that any potential complications are addressed promptly. If you notice any concerning changes in your vision, do not hesitate to seek medical advice. Your eye health is paramount, and proactive management is key to maintaining it.
