Is this ptosis? Do I need to see an oculoplastic surgeon? (photo)

Thank you for posting your question here!My answer will be based on the limited information and pictures provided, for a more detailed and bespoke plan please consult with your plastic/occuloplastic surgeon in person.
From your picture it does appear that you do have ptosis going on , you have different upper eyelid folds (superior palpebral sulcus) which is likely secondary to detachment of the levator muscle which leads to ptosis. This can be corrected by a levator advancement surgery and re-attaching the levator to the aponeurosis .I hope this helps, best of luck!

If your surgeon doesn't know how to fix this then you surely need to see someone who does. Ocular plastic surgeons are ophthalmologists with extra training in plastic surgery techniques around the eye.
Many Plastic Surgeons 2 to 5 years of plastic surgery training are well trained in treating this condition. Ask if the surgeon you see is familiar with ptosis correction before you make another appointment.
