Mild eyelid ptosis with good elevator function can be treated with minimally invasive procedures. When Muller’s muscle contraction corrects the deficiency (evaluated by phenilefrine test) conjunctivo-mullerectomy is the procedure of choice.
This video presents the surgical steps to perform conjunctivo-mullerectomy.
