Asymmetrical eyes: My right eye is smaller than my left, seems to have gotten worse with time, what could be causing it? (photo)

More than likely the asymmetry of your eyelids is just a feature. Nevertheless there are certain things that can generate this and should be ruled out before discussing any specific therapy. You should consult with a plastic surgeon or oculoplastic surgeon for a complete evaluation.

See an oculoplastic specialist. The asymmetry is likely from combination of upper eyelid height difference (with right side more droopy, called ptosis) and possible from one eye being more bulgy than the other or one eye being more sunken than the other.  Treatment depends on the exact problem.

Yes there are plastic surgeon and facial plastic surgeons who may offer ptosis surgery.  However, this is not more than a side line for these specialties.  You are best served seeing an oculoplastic surgeon.  Your options are either travel south to Seattle or go to Anchorage, where Carl Rosen, the only fellowship trained oculoplastic surgeon in the state of Alaska practices.  You have ptosis and this can be addressed surgically.

Since you are stating that the problem has become worse over time in my opinion this could possibly be a ptosis meaning your internal muscles may not be as strong as they once were. However, you would need to come in for an evaluation to be sure - consult a surgeon or oculoplastic surgeon to get an opinion. Surgery may be an option.Hope this was helpful!
