One eye is bigger than the other and it looks a little bit cross-eyed. Treatment options? (photos)

Eye asymmetry is complex 3D issue and it needs careful evaluation. It could be due to eyeball position or eyelids. See an expert oculoplastic specialist.

Thank you for your question and photos. I believe I would begin by scheduling an appointment with an ophthalmologist to determine whether treatment is needed for the eye. Once you have been examined, you can consider scheduling a consultation with a board-certified plastic surgeon to see if eyelid surgery might create better symmetry between the eyes.
