Going through this whole process right now. During both the DAV med records review and the VA med records review, no one asked or cared about NVGs or anything else.

They look at what's in your records, annotate the big medical items, then a VA doctor reviews your records and gives you a physical. During the physical he doesn't give a crap about your stories, only what impact those big medical issues will have on your ability to work post-retirement. They won't even let you start the discussion of "no sh!t, there I was, NVGs in a 4Vx, blah blah." They want to hear the specifics of range of motion limitations, pain level doing work-related tasks, etc.

If it ain't in the records and doesn't directly impact your ability to work, they don't care.
