Could visual snow dissipate when depersonalization leaves?

Could visual snow dissipate when depersonalization leaves?

Yes, depending: Visual changes are not unusual in depersonalization, and moreso derealization. If the symptoms come and go, then the visual snow effect may dissipate when the dissociative symptoms resolve. As usual, symptoms like this are found with other conditions, and a good medical evaluation is in order if it has not been done yet, before attributing this to depersonalization, or a related issue. ...Read more

Vision has gotten really blurry lately & I see visual snow in my vision even with glasses on. This started before the glasses as well. What's going on?

Time for exam: If the snow is there all the time, you really need to see your eye doctor for a full exam. Cover each eye separately to see if it's in one or both eyes. Make sure to describe it as well as you can for the doctor. If the snow comes and goes, it could be related to low blood pressure or with migraines (if you're prone to headaches). Good luck! ...Read more

The cause is unknown but researchers this year have discovered an area of abnormal brain function (hyper metabolism) on functional MRI that appears to be the cause. Much more work needs to be done scientifically. Unfortunately, for now there is no definite evidence of a specific treatment. ...Read more

Entopics: At your age, you are probably seeing what is termed entoptic phenomena (also known as flying corpuscles). In the right light against a uniform background like a blue sky or a clear wall, you see rapidly moving tiny blobs which represent the circulation in the center of your vision. This is normal. If this does not describe this, then you might check in with a neuro-ophthalmologist. ...Read more
