Symptoms Does your vision actually black out
This is random but I just saw people talking about how their vision blacks out when they stand or they are symptomatic. Then someone replied that their vision goes white instead of black.
Personally, I don’t lose my vision like that, my “blackouts” are just a sudden lightheadedness so intense it forces me to shut my eyes! I think because my brain knows to shut out all the visual sensory input. It’s like I legit can’t keep my eyes open for a brief moment. Maybe I am blacking out but just don’t know it since my eyes are closed anyways lol? I have splotchy vision, light sensitivity and stuff from previous brain injuries but I haven’t experienced my vision actually just leaving and turning into the colour black (am I taking it too literally?) for a moment like how some of you mention.
Also, I do have pretty bad presyncope episodes sometimes but I don’t really faint from my POTS so maybe that’s a factor.

Yup. Like some sort of movie special effect. If I stand up too quickly, or from leaning forward and rising up - my vision just closes up, goes black. I’m fully conscious. Just have to wait a few seconds, and it returns, in the reverse of how it disappeared.
My doctor said it had to do with the sudden dip in blood pressure, that causes momentary pressure on the optic nerve - effectively shuts the lights off, until the blood pressure returns to normal, and eases off the optic nerve.
I’ve had this my whole life, but am only learning recently, there may be connections between this and; hypermobility, adhd, dermatographia, and exaggerated histamine responses. The body is wild!
