Ptosis is the drooping of the upper eyelid, which can affect one or both eyes. It can be caused by aging, muscle weakness, nerve damage, or underlying medical conditions. Treatment options include eyelid surgery (blepharoplasty) to lift the eyelid, and in some cases, nonsurgical treatments like special glasses with a crutch to support the eyelid. Addressing underlying conditions, like nerve or muscle disorders, may also be necessary.For more information, contact Dr. Maria's Eye Clinic, Saligramam, Chennai, near Vadapalani, Virugambakkam, and Kodambakkam.
