Black dots/pixel in dark background

So for the past 7 years I am suffering from visual snow but this symptom is quite strange to me because I am not able to find the reason of this particular symptom. In the dark i have number of black dots or pixel that twinkles when I am staring at something dark and also these dots turns to green when staring at something bright. This phenomena strongly suggest to me it is related to the photoreceptors of the eye but then visual snow is know to be an neurological disorder I have gone through multiple dilation and OCT exam in the past 7 years all were normal.

I also read an article about Autoimmune Retinopathy(AIR) in that photoreceptors were attacked by the immune system creating scotoma but I am not sure that these dots are those scotoma further as suffering from the past 7 years AIR highly seems unlikely but this doubt is killing me everyday it made me a hypochondriac.

does someone also suffer from such symptom I am really feeling alone and lost in life.

I have attached 2 gifs the first one describing when I stare something dark the second one describing when I stare at something bright and immediately look at less bright.
