โ— It is the most common form of acquired ptosis due to dehiscence or disinsertion of the levator aponeurosis for anterior surface of the tarsus.โฃ

โ— The Levator palpebrae superioris is the primary muscle responsible for the elevation of the eyelid. It is supplied by the third cranial nerve (superior division).โฃ

โ— It may be unilateral/ bilateral.โฃ

โ— It may be mild (1โ€“2 mm), moderate (3โ€“4 mm), or severe (>4 mm).

โ— Involutional โ†’ Due to aging, levator muscle becomes thin โ†’ loss of muscle tone and inability to hold the upper lid in proper positionโฃ

โ— Drooping of eyelid with reduction of palpebral fissure heightโฃ

โ— Elevated lid crease on the affected sideโฃ

โ— Increased pre-tarsal show (margin- crease distance is increased)โฃ

โ— Skin over eyelid is thinned outโฃ

โ— Sulcus is deepโฃ

โ— No lid lag on downgaze ie lid drops and ptosis worsens on downgaze โ†’ symptoms worse on downgaze/ while readingโฃ

โ— Patient may compensate with overaction of the frontalisโฃ

โ— Good levator functionโฃ

โ— Extraocular muscle movements and pupil are ๐—ป๐—ผ๐˜ involvedโฃ

โ— The goal of surgery is to reattach a disinserted or dehisced aponeurosis to the superior anterior surface of the tarsus, or shorten and tighten a weak levator muscleโฃ

A partial thickness suture is passed through the tarsus and through the levator muscle, resulting in an advancement of the levator muscle.โฃ
