One of my eyes is dropping. What is causing this/can it be fixed?

Thank you for your question.  I am sorry to learn about your concerns.  The diagnosis of Silent Sinus Syndrome is confirmed by CT scanning. I would be hesitant to make definitive treatment recommendations until the diagnosis is confirmed.  I would recommend examination by an Oculoplastic Surgeon who could then order the necessary scan and recommend a treatment plan.  Best of luck.

That is a sinus condition where typically one of the maxillary sinus does not ventilate due to chronic sinusitis.  The sinus overtime collapses.  Since the top of the sinus is the floor of the orbit supporting the eye, the eye begins to sink in.  However from the photo of you looking up, the two eyes project equally making this highly improbable.  On the other head you do demonstrate bilateral anterior levator dehiscence.  You have minimal ptosis but slightly more brow compensation on the left side but the right side is also elevated.   In my experience, both sides would esthetically benefit from repair of the levator.  The big benefit will be relaxation of the eyebrow position with improved symmetry.  I will caution you that there are two types of ptosis repair: posterior and anterior approach.  The posterior approach is called a Mullerectomy.  It is highly popular for a variety of reasons.  In my opinion, that approach is not the right one for this type of situation. There is no rush here for you to have surgery.  You can take your time to find the right surgeon.  You need someone who is an oculoplastic surgeon truly specialized in performing aesthetic eyelid surgery.

Best to see an oculoplastic specialist for evaluation. It does appear your left upper eyelid is droopy, called ptosis, which causes the same side eyebrow to elevate to assist raise the the droopy eyelid. See link below.

Ptosis is the drooping of an eyelid. It can occur for numerous reasons, including but not limited to contact lens use, rubbing the eye and aging. An Oculoplastic Surgeon can determine appropriate workup for you and guide you with an appropriate treatment plan.  Good luck,

You are correct, you have asymmetric tear troughs. This is most likely due to asymmetry in your underlying bony structure around this area, plus how the muscles and fat in the area drape onto the bone. Sometimes these asymmetries are exacerbated by weight loss. The best first step is to see a facial plastic surgeon or oculoplastic surgeon for an examination. Sometimes fillers can help correct this problem; sometimes surgery can help.
