The SpOTT diagnosis for ME/CFS

According to Google, Troxler’s fading should take from tens of seconds to a few minutes.

Increased time or absence of Troxler’s fading indicates difficulty suppressing sensory input.

Maybe we're exhausted because we can't ignore irrelevant signals.

I can’t get the knots or nails in the roof to disappear completely. They sometimes get washed out or smudged after anything from five seconds to never after five minutes.

Some of the times I’m tried the side vision gets really blurry and it looks like the light playing at the bottom of a wavy pool. That’s in addition to lots of other visual symptoms that I always have.

Blinking instantly resets everything.

Could be. Which is Troxler's? Is that the peripheral fading? I think that is much quicker for me than the target disappearing.

Very healthy husband couldn't do it, gave up 3 times after 61sec, 50sec, 51sec. Had to blink at that point

I'm not sure.

The spot doesn't disappear after a minute for a healthy control I tested it with.

65secs
110secs
105secs

Spot did not disappear but I had to stop because my eyeballs became so sore.

Peripheral vision went grey.

 

[Jonathan Edwards]

It tends to take more than a minute for me, maybe two or three but I don't think more.

 

[OrganicChilli]

Isn't this mostly an endurance test? If blinking is strictly not allowed?

It feels like it! It's so painful I've never got beyond 16 seconds.
