Vertical tarsal buckling as a complication of levator aponeurosis repair for acquired blepharoptosis.
In two patients (a 60-year-old man and a 69-year-old woman) vertical buckling of the superior tarsus followed surgery to correct levator aponeurosis disinsertions for the management of acquired upper eyelid blepharoptosis. The superior tarsus rotated posteriorly and folded on itself because the sutures reattaching the levator aponeurosis to the tarsus were placed too low on the anterior tarsal plate. This complication can be prevented by placing the tarsal sutures above the vertical midpoint of the tarsus. If this complication develops, early correction is possible by revising the suture heights and keeping the tarsus flat with a symblepharon ring. This led to a satisfactory outcome in one of our cases. Late correction of vertical tarsal buckling requires excision of the buckled tarsus and repositioning the levator aponeurosis sutures. In one of our patients, an entropion developed as a result of insufficient vertical tarsal height that caused instability of the upper eyelid. The outcome was otherwise satisfactory.
