Case of suspected pathologies associated with high myopia?
Hello Doctor: Recently (for almost three months), I have been experiencing a multitude of transparent white spots or black shadows flickering in my field of vision (they are more noticeable in a dark room or against a single-colored wall), similar to the images seen in visual snow syndrome (https://en.wikipedia.org/wiki/Visual_snow).
I visited a medical center, and the doctor suspected it was related to my myopia (with vitreous traction and vitreous liquefaction) as I have about 600 degrees of myopia, along with symptoms of peripheral retinal degeneration.
I have also undergone laser experiments (green laser, a few mW, without protective eyewear).
I am wondering if it is possible that prolonged exposure to bright light has caused elongation of the eye axis or retinal damage? (The hospital doctor believes it is not the case).
Can you please tell me if there are indeed cases in clinical practice where myopia has led to such conditions? The hospital doctor also mentioned that myopia is a structural issue; could you explain what a structural issue means in ophthalmology? There seems to be a lack of information on this topic online.
Is it true that this condition cannot be completely cured? Because aside from retinal hole repair, the hospital doctor did not suggest any further treatment.
If the visual noise does not move, does that indicate a retinal issue rather than a vitreous issue? Thank you for taking the time to respond.

Hello, Genghis Khan VI: If the fundus examination shows no significant lesions, this condition may be related to issues with the vitreous body.
Laser treatment does not cause axial elongation-related lesions, but it can lead to retinal damage, so it is essential to wear protective goggles during laser procedures.
The cause and treatment of visual snow syndrome have not yet been identified, although some studies suggest a correlation with migraines.
The ophthalmology department at Puzi Hospital in Taiwan is open on Monday, Tuesday, Thursday, and Friday mornings from 8:00 AM to 12:00 PM, and Wednesday afternoons from 1:00 PM to 4:30 PM.
Online responses should only be used as a reference; it is necessary to seek medical attention at healthcare facilities when needed.
I hope to have the opportunity to serve you.

More Info
High myopia, also known as pathological myopia, is a severe form of nearsightedness that can lead to various ocular complications, including retinal detachment, macular degeneration, and other structural changes in the eye. Your symptoms of seeing numerous transparent white spots or black shadows, particularly in low-light conditions or against a single-color background, can indeed be concerning and warrant further investigation.
Symptoms and Risks of High Myopia
Individuals with high myopia often experience visual disturbances due to changes in the vitreous body and retina. The vitreous gel, which fills the eye, can undergo liquefaction and shrinkage, leading to vitreous detachment. This can manifest as floaters or flashes of light. The presence of static spots, as you described, may indicate that there is some degree of retinal involvement, especially if you have a history of peripheral retinal degeneration.
The structural changes associated with high myopia include elongation of the eyeball, which can stretch the retina and lead to thinning or degeneration. This is what is often referred to as a "structural issue" in the context of high myopia. The retina may become more susceptible to tears or detachments, particularly in the periphery, where degenerative changes are more common.
Potential Causes of Your Symptoms
Regarding your concern about the potential impact of prolonged exposure to strong light, such as from laser experiments, while there is some evidence that excessive UV or blue light exposure can contribute to retinal damage, the primary concern in high myopia is the structural changes that occur within the eye itself. The elongation of the eyeball and changes in the vitreous are more directly related to the symptoms you are experiencing.
Treatment Options
Currently, there is no definitive cure for high myopia, and management typically focuses on monitoring and addressing complications as they arise. If your symptoms are due to retinal issues, such as tears or detachments, surgical interventions like laser photocoagulation or vitrectomy may be necessary. Regular follow-ups with an ophthalmologist are crucial to monitor the condition of your retina and vitreous.
In terms of managing your symptoms, it is essential to maintain regular eye examinations, especially if you notice any changes in your vision. Protective eyewear may be beneficial if you are exposed to bright lights frequently, and discussing lifestyle modifications with your eye care provider can help mitigate some risks associated with high myopia.
Conclusion
In summary, high myopia can lead to significant ocular complications, and your symptoms warrant careful evaluation. While structural changes in the eye are a primary concern, the presence of static visual disturbances may indicate retinal involvement. Regular monitoring and appropriate interventions are key to managing your condition. If you have ongoing concerns or if your symptoms worsen, seeking a second opinion or further evaluation from a retinal specialist may provide additional insights and treatment options.
