Hello emefh7, While your upper eyelids do appear to be asymmetric, it does not appear that ptosis is the major culprit. One way to diagnose ptosis, which is an abnormally low lid, is to measure the distance between your upper lid margin and the light reflex point on your eye when you are looking at a fixed point. This is called the MRD-1. You should see a plastic surgeon in consultation to have a thorough eye and eyelid exam to determine this measurement as well as other measurements of upper lid function. Your asymmetry appears to be related to at least two factors: dermatochalasis, which is excess skin of the lid, and asymmetric supratarsal folds. These can be addressed with blepharoplasty surgery.
