Yes, my spot shows up in the Amsler grid. It is in the upper right quadrant. It appears as a whole, with the grid line
s becoming slightly distorted as they "fall into" the whole.
Yes, I can see through the spot. It is not a totally blocked scotoma. Sometimes it appears light grey. Other times it is almost pinkish. Sometimes blue. It looks very much like the afterimage of a bright light and goes through the same variations of color. But it is never a black, opaque spot.
