Similarities between VSS and orthostatic hypotension

When I talk about "orthostatic hypotension", I mean the associated phenomen of temporary vision loss that sometimes occurs when you stand up too quickly after laying down. For me that vision loss occurs as visual snow that gets so strong I only see black and white static for a few moments. The VSS I'm experiencing is like a very very mild version of that. Has anyone else noticed the similarity too? I know its unlikely, but can that correlation maybe help in finding out what exactly is causing VSS? I cant be the first one noticing how similar thede phenomena are right?
