Questions about the symptoms of retinal tears?
Hello, I have myopia with a degree of 600 to 700.
I previously asked questions regarding this issue in articles #202111 and #202245.
Recently, the frequency of flashes has increased, and based on recommendations, I underwent an ultra-widefield retinal examination a few days ago.
The doctor still indicated that there were no tears, and the retinal condition is good.
I was advised to monitor the situation and return for examination only if worse symptoms appear (such as an increase in floaters, dark shadows, or blurriness).
1.
Is the accuracy of the ultra-widefield retinal examination inferior to that of traditional dilated fundus examination? I have been experiencing increasing flashes, but all examinations have reported no issues.
Additionally, consultations at other clinics have indicated that dilated examinations are more common, leading me to question whether the ultra-widefield examination is less accurate and may have missed a tear.
Should I consider switching to another clinic for observation?
2.
If I wait for worse symptoms to appear, has the retina already detached? I have researched that flashes and light sensations are signs of retinal tears, which makes me constantly worry that my retina might have already torn at any moment.
However, the doctors have said everything is fine.
They suggest waiting until worse symptoms (such as an increase in floaters, dark shadows, or blurriness) appear before re-examining.
Is it too late by the time these symptoms occur? I am very concerned that the retina may have already detached by then.
3.
Seeing flashes only when my eyes are open—does this indicate a retinal tear? I have found that flashes and light sensations occur within the eye, so theoretically, I should be able to see them even with my eyes closed.
However, I only notice the flashes when my eyes are open and moving.
I have tried moving my eyes while closed and in a completely dark room, but I did not see any flashes.
Does this still indicate a potential retinal tear?

Hello:
1.
Accuracy of Ultra-Widefield Retinal Imaging: Ultra-widefield retinal imaging is an advanced examination method that provides a broader range of retinal images.
Traditional dilated fundus examination remains a common method, especially for a more detailed assessment of subtle changes on the retinal surface.
Both methods have their advantages, but there is no absolute difference in accuracy.
Ultra-widefield imaging may have an advantage in observing the peripheral areas of the retina.
2.
Timing for Monitoring Worsening Conditions: The reason a physician may recommend continued observation could be that the current examination has not revealed any retinal tears or other abnormalities.
Retinal issues typically present with more severe symptoms, such as floaters, shadows, or blurriness.
The physician may consider ongoing monitoring to ensure any changes can be detected early.
3.
Signs of Lightning and Flashes: Not seeing flashes when closing the eyes and moving them does not necessarily indicate that there is no problem.
Flashes or lightning may be symptoms of retinal tears but could also be related to other ocular conditions.
When the eyes are closed, changes in visual signals may prevent perception of these phenomena.

More Info
Understanding retinal tear symptoms and the associated concerns can be quite complex, especially for individuals with a history of high myopia, as you have described. Your situation raises several important questions regarding the accuracy of retinal examinations, the significance of symptoms like flashes and floaters, and the timing of medical intervention. Let's address your concerns one by one.
1. Accuracy of Wide-Angle Retinal Examination vs. Traditional Dilated Fundus Examination: Wide-angle retinal imaging is a relatively newer technology that allows for a broader view of the retina without the need for dilation. While it can be very effective in identifying certain retinal conditions, traditional dilated fundus examinations still hold significant value, particularly for detecting subtle changes or tears that may not be as easily visible in wide-angle images. If you are experiencing increasing symptoms like flashes, it is reasonable to seek a second opinion or request a traditional dilated examination, especially given your high myopia, which increases the risk of retinal tears and detachments.
2. Concerns About Waiting for Symptoms to Worsen: It is understandable to be anxious about waiting for symptoms to escalate before seeking further evaluation. Flashes of light can indeed be a sign of retinal irritation or potential tears, and while not every instance leads to a retinal detachment, it is crucial to monitor these symptoms closely. If your doctor has advised you to wait until you experience more severe symptoms (like an increase in floaters, shadows, or blurred vision), it is based on their clinical judgment. However, if your symptoms are persistent or worsening, advocating for an earlier follow-up is entirely appropriate. Early detection of retinal issues can significantly improve outcomes.
3. Understanding Flashes and Their Implications: The experience of seeing flashes of light, particularly when moving your eyes, can be concerning. In many cases, these flashes are related to the vitreous gel pulling on the retina, which can happen with age or myopia. However, the fact that you only see these flashes when your eyes are open and moving does not necessarily rule out the possibility of a retinal issue. It is essential to communicate this specific symptom to your eye care provider, as it may warrant further investigation.
In summary, your concerns about retinal health are valid, especially given your myopic condition. It is crucial to maintain open communication with your eye care provider and to seek further evaluation if your symptoms persist or worsen. If you feel uncertain about the assessments you have received, seeking a second opinion from another ophthalmologist can provide additional reassurance and clarity. Remember that early detection and intervention are key in managing potential retinal issues effectively.
Additionally, managing anxiety about your eye health is important. Engaging in relaxation techniques, staying informed about your condition, and maintaining regular follow-ups can help you feel more in control of your situation. Always prioritize your eye health and do not hesitate to seek help when you feel it is necessary.
