What does a person with a negative scotoma see?

What does a person with a negative scotoma see? A black area? A white
area?

They see nothing in the scotoma area.

While looking staight ahead, consider what you "see" behind you. Is
it black or white or "nothing".

I can't imagine what having a massive negative scotoma would be like.
What do your negative scomata patients report? What does "seeing
nothing" mean?

The essence of negative scotoma is that the patient is unaware of the
loss. The example I used, "while looking forward, what do you see
directly behind your head" is what seeing nothing means. Not black,
not white, not a hole, not a lack, simply unaware and "nothing".

So if I were to move my finger through the area in the visual field
where a negative scotoma was, would it disappear while moving in it,
and reappear on the other side?

I suppose the world would be very strange if your entire visual field
was a negative scotoma.

Um...it doesn't. All it tells me I that I don't have AMD. But it's
unusable for my right eye, b/c it's acuity is so poor I can't see the
dot or grid.

Is ROP a form of wet MD?

Doesn't psychogenic blindness also cause that?
