Proper treatment of ectropion and entropion of the eyelids requires accurate identification of the underlying cause of the malposition.
Successful blepharoptosis repair requires correct diagnosis, thorough understanding of eyelid anatomy, thoughtful planning, and good surgical technique.
Important clinical measurements for evaluation of a patient with blepharoptosis include margin–reflex distance, vertical palpebral fissure height, upper eyelid crease position, levator function, and presence of lagophthalmos.
Chemodenervation with botulinum toxin is the mainstay of treatment for benign essential blepharospasm, with surgical myectomy considered in refractory cases.
Treatment options for brow ptosis include browpexy, direct eyebrow elevation, endoscopic forehead-lift, and pretrichial brow-lift.
