Optometrist, take two

I had my follow up appointment today to do a visual field test to check for early signs of glaucoma (due to my family history).  I did this or something similar a few years ago but had forgotten how tedious it is. You basically just stare at a light in the center of the “field” and press a button whenever you see flashes of light in the peripheral area. It takes about five or more minutes to do the main test, plus another minute or two to do a wider field (without a corrective lens). I had missed a few so it was necessary to repeat the whole thing and compare results. It’s expected that a few will be missed but they want to check if the same ones are missed. I missed a few of the same ones second time around so I get to go back in a couple weeks and do it all again. Oh what joy! From what I understand, there’s not really much of a pattern to my missed ones so it’s probably not indicative of anything at this point. I’m not quite sure what happens should I have similar results next time.
