What are the effects of unilateral ptosis & upper bleph on the opposite eye?

Question

1 year ago, I got unilateral ptosis & upper bleph on my left eye. Since then, my right eye seems to have lost volume on the outer corner. The eye lid also appears to have become more rounded out, whereas before it was much more horizontal. It just looks older and deflated now with the volume loss, almost as if a bleph was performed on it as well. Im aware of herring's law but this seems a bit beyond that description. Prefer not to upload photos at this time

The upper eyelid margin gets bilateral innervation from the brainstem but the eyebrows get separate unilateral innervation. This makes sorting out the effects of surgery less than straight forward. Removing upper eyelid skin (blepharoplasty) often stimulates the brow on the same side to relax down. Inflammation, healing,  and general wear and tear from surgery can have real and lasting effects on tissue volume. Lateral canthal disinsertion following surgery can also impact the appearance of the eyes. Without a detailed in person assessment is impossible to provide more insight into your concerns. Don't let your surgeon gas light you. The changes that you see are real and may not resolve without corrective surgery.
