A single word for "not seeing the big picture"

I am looking for a word that would describe being obsessed with the details of a larger entity such that the "looker" neglects to see the whole or (perhaps more importantly) the purpose of the whole.

Basically, "not seeing the big picture".

What can [more] succinctly describe this?

Edit: I just found this post: An adjective for "able to see the big picture". I think I want the exact opposite.

Solution 1:

How about myopic, which means short-sighted and therefore, both literally and figuratively not able to see the big picture?

Solution 2:

Shortsighted, tunnel-vision, hyper-focused, myopic, or unimaginative can all apply to this. As well as detail-oriented, anal, drudgeon, or dullard.

Solution 3:

How about "blinkered" (when a horse if forced to only see what is in front of them).

Solution 4:

What about omphalocentric, i.e. navel-gazing?
