Concerns about retinal detachment?


Hello, doctor.
A month ago, I suspected I had a retinal detachment and visited an ophthalmologist, where I underwent a dilated eye exam and OCT.
The doctor mentioned that one area of my retina was in the red zone (thinner), but everything else appeared normal, with no signs of tears.
However, since then, I have noticed some symptoms and couldn't find satisfactory answers online, so I am here to ask.
I have two main questions.

First, I have read that retinal detachment can cause flashes of light, so I have been deliberately observing for any unusual lights in dark areas.
Recently, while sleeping, I noticed high-frequency flashes in my peripheral vision with my eyes closed, about three times per second for approximately five minutes.
The intensity is not very strong, so it’s not very obvious, but this has occurred two or three times in the past week.
Should I consider having another dilated eye exam? Additionally, I have noticed that when I move my eyes, there is a more intense flash sensation at the upper edge of my right eye.
Could this be a precursor to retinal detachment?
The second part of my question is also something I observed while sleeping.
When I rapidly open and close my eyes, I feel that the center of my vision is darker, and it takes about a second for it to adjust to the same brightness as my peripheral vision.
I thought this might be because there are fewer rod cells in the center of the vision, leading to a slower adaptation.
Is this correct? Or could this be a sign of macular degeneration? (My left eye is -5.75 diopters with -1.75 astigmatism, and my right eye is -4.75 diopters with -1.25 astigmatism.)

Dear Mr.
Wu: Regarding the issue you raised, it is quite complex and not suitable for written discussion.
It is recommended that you visit the ophthalmology outpatient clinic for further examination.

Your concerns regarding potential retinal detachment and the symptoms you're experiencing are valid and warrant careful consideration. Retinal detachment is a serious condition that can lead to permanent vision loss if not treated promptly. Let's break down your symptoms and questions to provide a clearer understanding.


Symptoms and Concerns
1. Flashing Lights: The presence of flashes of light, especially in the peripheral vision, can indeed be a sign of retinal detachment or other retinal issues. These flashes occur due to the vitreous gel in the eye pulling on the retina, which can happen as we age or due to other factors. If you are experiencing flashes of light, particularly if they are new or have increased in frequency, it is essential to consult with an eye care professional as soon as possible.

2. Darkening of Central Vision: The sensation of your central vision appearing darker after rapid eye movement could be related to several factors. One possibility is that it is a normal physiological response as your eyes adjust to changes in light and focus. However, if this sensation is accompanied by other symptoms, such as persistent flashes or floaters, it could indicate a more serious issue, including potential macular degeneration or other retinal conditions.

3. Vitreous Detachment: Given your history of high myopia (nearsightedness), you are at a higher risk for vitreous detachment and retinal issues. The vitreous gel can become more liquid and pull away from the retina, leading to symptoms like flashes and floaters. This process can sometimes lead to retinal tears or detachment, especially in individuals with high myopia.


Recommendations
- Follow-Up Examination: Since you have already undergone a dilated eye exam and OCT (Optical Coherence Tomography) that showed a thin area of the retina but no tears, it is crucial to keep monitoring your symptoms. If the flashes increase in frequency or intensity, or if you notice any new floaters or changes in vision, you should seek an immediate follow-up with your eye doctor. They may recommend another dilated exam to ensure there are no changes in your retinal condition.

- Understanding Retinal Health: It’s important to understand that while flashes and floaters are common, especially in individuals with high myopia, they should not be ignored. Regular eye exams are essential for monitoring your retinal health, particularly as you age or if you notice changes in your vision.

- Managing Anxiety: It’s natural to feel anxious about potential vision problems, especially after researching symptoms online. However, it's crucial to rely on professional medical advice rather than self-diagnosing based on internet searches. If you feel overwhelmed, consider discussing your concerns with your eye care provider, who can provide reassurance and clarity.


Conclusion
In summary, while your symptoms could be related to normal changes in the eye, they could also indicate more serious conditions that require attention. Given your history of high myopia and the symptoms you describe, it is advisable to maintain regular check-ups with your ophthalmologist and report any new or worsening symptoms immediately. Early detection and treatment are key to preserving your vision and preventing complications.
