Thank your for the question and photo. Your photo shows that the margin of one eyelid is closer to the pupil than the other. This can be because one eye lid is lower than the other or that the eyeball of that eye is in a different position. An in-depth discussion and exam will allow the surgeon to diagnose the source of the asymmetry. Congenital ptosis involve the mechanics of the eye lid itself in terms of being positioned lower than a normal eyelid. This can be corrected with surgery depending on the function of the eyelid itself. You will have to be evaluate by a plastic surgeon or an opthalmologist to start the process.
All the best,
Dr Remus Repta
