very annoying article where no research has been done, the pilot was on mirtazapine, this can cause visual snow and flashing vision, it did it to me and if you google it you will find many other people complaining of the same thing. a lot of antidepressants cause visual snow, the worst thing you can do to someone with a real problem is tell them its in their head. when he complained of his symptoms they upped his mirtazapine dose. in this case it wasn't just him that was affected by the handing out of these awful drugs but everyone on the plane. when will society wake up to the things anti depressants do to our visual cortex and retinas. they work on gaba receptors and these are in the eye too.
