Eye/brow/lid ptosis? Orbital dystopia, "shrinking eye"? (Photos)

Not sure what's going on with my right eye. Eyelid/eyebrow ptosis fluctuates wildly (to different levels) and the lower corner & lateral canthus looks to be thinning/very hollow. The eyelashes also slope down, and in general the eye looks like it's sinking into my skull. It also feels heavy. I'm consulting with a neurologist in the next month, but wanted to get some thoughts and possible treatment from a cosmetic perspective. Photos added with differing light to emphasis contrast. Thank you
