Visual Disturbances: Insights on Flashing Lights and Eye Symptoms - Neurology

Frequent bright spots and flashes in the eyes are indicative of enhanced Scherer's symptom?

---

Hello Doctor, I am really very anxious and I seek your help to understand what might be wrong with me.
I apologize for the lengthy message.
My symptoms started in January after I bought a VR headset out of curiosity and used it for two months.
After pressing my eyeball with my finger once, I developed floaters in my vision.
I went to an ophthalmology clinic for an examination, and there were no major issues; it was diagnosed as physiological floaters.
However, afterwards, I began to see many bright spots moving around when looking at the sky, similar to the symptoms described online as Scheerer's phenomenon.
Last week, I visited the ophthalmology department at Renai Hospital in Taipei and underwent another dilated fundus examination, which again showed no significant problems.
The ophthalmologist assured me that the structure of my eyes is definitely fine and that I do not need to undergo an eye CT scan.
He suggested that I see a neurologist.
1.
Recently, I feel that the Scheerer's phenomenon has gradually worsened.
When I look at bright areas, including sunlit asphalt roads and illuminated books, I see bright spots moving along fixed paths (the spots are not very dense, resembling white blood cells in blood vessels).
I also occasionally experience a sensation similar to visual snow, and I see two fixed bright spots, but they disappear with a blink or a quick glance.
There are also very bright fixed spots that feel like strong light, and they also disappear with a blink.
The bright spots are very small, approximately less than 0.5 mm in size.
2.
When looking at distant black objects (such as black cars or tree shadows) in bright light, I see strange, extremely dark patches flickering around my focal point.
However, these symptoms do not occur when I close my eyes in the dark, and both eyes are affected.
3.
Last year, I often felt a trembling sensation inside my body when lying flat (similar to the feeling of nerves shaking after exerting my hand).
When I was close to falling asleep, I also experienced a migraine-like flashing sensation in my eyes that lasted from 10 seconds to 5 minutes, occurring in both eyes, but without an actual migraine.
I felt a pressure in the back of my head, which alleviated after I fell asleep, and I did not wake up with a headache.
Sometimes, I also see flashes when looking at fluorescent lights in dim places; it’s not a bright flash, but rather a dimming, like a faulty light bulb.
4.
During that time, I was under a lot of stress due to final exams, and I consulted a cardiologist and an endocrinologist.
The cardiologist noted that I have some sinus arrhythmia but no major issues.
I underwent an echocardiogram and a 24-hour ECG, both of which were normal.
The endocrinologist conducted tests for the autonomic nervous system and blood tests, all of which were also normal.
5.
The frequent flashing sensation in my eyes has recently diminished, but over the past two months, I have started to feel pressure in the back of my head near the neck and occipital region when lying flat.
I need to sit up to relieve it, but it subsides after I fall asleep.
I also experience some tinnitus and a high-frequency ringing in my ears, with the sensation of pressure in the back of my head and around my ears.
6.
Recently, when I am about to fall asleep or get startled awake, I see a flash of white light, which makes me fear that something might be wrong with my brain.
My sleep schedule is not very irregular; I have been going to bed around midnight and waking up around 7 AM for the past two years.
However, since the onset of the floaters, I have been very worried.
7.
Additionally, my blood pressure tends to be on the higher side, around 120-140 over 80-90.
8.
I really love playing the piano.
I started playing at three and a half years old and have played a lot throughout high school and college.
I would like to ask the doctor if playing the piano has any significant negative effects on the nervous system.
I have many questions and feel quite helpless.
I sincerely ask for your help in clarifying these issues.
I would be extremely grateful.
Thank you for reading this, from a very anxious college student.
