Eye Movement Issues: Causes and Concerns Explained - Ophthalmology

Eye concerns?


Hello, doctor: My eyes sometimes involuntarily drift rapidly, suddenly moving quickly from side to side.
What is this phenomenon? Additionally, when I go to sleep at night with all the lights off, I see bright or dark moving spots whether my eyes are closed or open.
My line of sight seems to follow these movements, and sometimes it even leads to complete darkness where I can't see anything.
However, when I turn on the light, I can see again.
What could this situation be? I have a myopia of 1000 degrees.
Thank you.

Hello, Xiao Ke: Your eyes may sometimes experience involuntary rapid movements, which could be a sign of nystagmus.
Given your high myopia, this phenomenon may be caused by retinal degeneration.
I recommend that you visit an ophthalmologist for an examination.
At Taiwan E-Hospital Puzi Hospital, the ophthalmology department is open Monday to Friday from 8:00 AM to 12:00 PM and Wednesday afternoons from 1:00 PM to 4:30 PM.
I hope we have the opportunity to serve you.
Best regards, Gao Pi-Lin.

Hello! Thank you for your detailed description of your eye movement issues. Based on your symptoms, it sounds like you may be experiencing a combination of eye movement disorders and visual disturbances that can be quite concerning. Let’s break down your symptoms and explore potential causes and concerns.


Eye Movement Issues
The phenomenon of your eyes moving rapidly and involuntarily could be indicative of a condition known as nystagmus. Nystagmus is characterized by uncontrolled eye movements, which can be horizontal, vertical, or rotary. This condition can be congenital (present at birth) or acquired due to various factors such as neurological disorders, inner ear problems, or even certain medications. The rapid movement of your eyes may lead to difficulties in focusing and can cause visual disturbances.


Visual Disturbances in Low Light
Your experience of seeing bright or dark moving spots when the lights are off, regardless of whether your eyes are open or closed, may be related to a few different phenomena:
1. Phosphenes: These are the sensations of seeing light without light actually entering the eye, often caused by pressure on the retina or spontaneous activity in the visual system. They can occur in dark environments when your eyes are adjusting to low light.

2. Visual Snow Syndrome: This is a neurological condition where individuals see a persistent "snow" or "static" in their visual field, which can be more pronounced in low-light conditions.

3. Retinal Issues: If you are experiencing significant changes in your vision, especially if it leads to temporary blindness (as you mentioned seeing black), it’s crucial to consider potential retinal problems. Conditions like retinal detachment or vitreous detachment can cause sudden changes in vision and should be evaluated by an eye care professional immediately.


Nearsightedness and Its Impact
With a prescription of -10.00 diopters, you are considered highly nearsighted (myopic). High myopia can increase the risk of various eye conditions, including retinal detachment, glaucoma, and cataracts. It’s essential to have regular eye exams to monitor your eye health, especially given your degree of myopia.


Recommendations
1. Seek an Eye Specialist: Given the complexity of your symptoms, it is highly advisable to consult with an ophthalmologist or a neuro-ophthalmologist. They can perform a comprehensive eye examination, including visual field tests and possibly imaging studies, to determine the underlying cause of your symptoms.

2. Document Symptoms: Keep a journal of your symptoms, noting when they occur, their duration, and any associated activities or environmental factors. This information can be invaluable for your healthcare provider.

3. Avoid Self-Diagnosis: While it’s tempting to search for answers online, self-diagnosing can lead to unnecessary anxiety or misinterpretation of symptoms. Rely on professional evaluations for accurate diagnosis and treatment.

4. Consider Visual Therapy: If your eye movements are linked to a condition like nystagmus, vision therapy may help improve your control over eye movements and enhance visual function.

5. Regular Eye Check-Ups: Ensure you have regular check-ups with your eye care provider to monitor your myopia and any potential complications associated with it.

In conclusion, your symptoms warrant a thorough evaluation by a medical professional. Understanding the underlying causes of your eye movement issues and visual disturbances is crucial for effective management and maintaining your overall eye health. Please prioritize scheduling an appointment with an eye specialist to address these concerns. Thank you for sharing your experience, and I wish you the best in your journey toward better eye health!
