Does every part of the eye see the same?

I'm having a breakdown right now, I'm a 19 year old girl, no known health conditions, my last eye exam was couple months ago, all aspects appear good, it was with a optometrist and then a ophthalmologist. I'm not sure if this was there back then because I never looked. to my question....

If I make my mouse cursor black and reduce it's size a little bit to about the size of the letter ''e'' in this sentence. In certain spots against a white screen, it appears to ''vanish'', this is exactly the same for both eyes in the exactly same areas. Although if my background is black and the cursor is white, it doesn't appear to vanish, or atleast it does but not enough. These ''tiny areas'' are most defiantly symmetrical  and appear to literally be where the retinal veins run along. I know this sounds very very odd, I will bring it up next appointment but what are the chances that I have some dreadful, symmetrical disease going unnoticed for however long it's been there??? I know RNFL isn't equal everywhere, but these ''spots'' are not very big, and both eyes?

I think you have discovered your physiological blind spots.  Google and read about them. It is a tiny hole in our vision where the images fall on the optic nerve head.  The optic nerve head has not retina over it thus does not 'see'.  Our brain normally fills in the blind spot but it is easily mapped out in visual field testing and if one eye is carefully tested you can make things like the tip of your finger disappear.  It is towards the ear side of each eye (temporal).

Sorry the areas I’m referring to are intact outside of the optic nerve blind spot. Theyre most certainly very very small, same spot in both eyes and don’t seem to be able to pick up what I described above? Does this sound like something to you, I don’t believe diseases happen symmetrically. Although it isn’t neurological as the points are slightly off for each eye but most certainly in the same areas precisely. My MD thinks perhaps when I was younger I may have had a accident staring at the sun or something, or perhaps the small areas I’m noticing is where your eye isn’t as strong to pick up a small pinpoint of light, but does intact pick up a brighter stimula if that makes sense.
Can't think of any thing that would make it exactly symmetrical. If you ophthalmologist isn't seeing any pathology I would just watch it and move on
Thankyou, I know this may seem odd but the only thing I can really find is of retinas pigmentosa that can be symmetrical... I’ve recently been to a optometrist, retinal specialist, Ophthalmologist and back to a optometrist in the last 4 months. I am not at all certain when this appeared, but i never purposely looked for it, my last appointment was two days ago with a optometrist who was very thorough, I’m not saying I have anything against optometrist but I do worry they miss things sometimes, but do you think they could’ve missed something like that on examination? They dilated my eyes, looked at the back multiple times, took photos, even tested for glaucoma aswell as my rnfl graph, yet my paranoid side is thinking perhaps they didn’t notice that tiny spot on my retina. Any feedback would be good this has me worried I’m  only 19
I think you concerned is likely misplaced given the number of eye doctors you've seen.  I would quit obsessing on it, stop trying to find the areas and move on with your life. Retinitis pigmentosa would be easy to diagnosis and causes profound visual field loss.
Thankyou alot
You are welcome. If something changes you can return to the eye doctor you have most confidence in.  If you do this a lot try and deal with problems in a healthy manner.
