The A-frame operation for acquired blepharoptosis
R. G. Small
The A-frame operation has been found effective in the treatment of acquired
blepharoptosis. It has the following advantages: (1) it can be done easily,
rapidly, and if desired, bilaterally, with a minimum of dissection; (2)
corneal irritation is not seen; (3) the tarsus is not disturbed; (4) since
it is done through an external incision, it can be done with a concomitant
blepharoplasty or other oculoplastic procedure; and (5) the procedure is
easily learned. The operation is a block resection of levator aponeurosis,
Muller's muscle, and conjunctiva. The term "A-frame" was adopted from the
use of temporary traction sutures to pull up the layers to be resected,
suggesting an A-frame building. The results in 40 eyelids are presented
with two illustrative case histories.
