Hello doctor,

I am a 37-year-old, healthy male. I have attached three views of my eyes. The top one is 13 years old, the middle one and the bottom one are from today. As you can see I always had a bit of droopy left eye lid and its prominence depends on the angle of the view. Do you think this is consistent with Horner syndrome? I have no neurological symptoms or health concerns.



Welcome to Horner syndrome is characterized by myosis (small pupil) and enophthalmos (eye turned inside) besides ptosis. It is usually associated with other symptoms like severe headache, dizziness, etc. So, I definitely do not think that you have this syndrome. As you do not have any other symptoms, there is no reason to worry about. In my opinion, it could be a normal face asymmetry. If you have double vision, especially at the end of the day, or if the ptosis is more visible at the end of the day compared to the morning, I would recommend performing nerve conduction studies in order to investigate for myasthenia gravis.
