Blindness following blepharoplasty: two case reports, and a discussion of management.

We present two cases of unilateral permanent visual loss following four-eyelid blepharoplasty. Clinical and radiographic evidence suggested orbital hemorrhage was the cause of visual loss in both cases. In particular, electrophysiologic tests indicated that optic nerve dysfunction, and not retinal ischemia, was responsible for loss of vision. Timely orbital decompression is the cornerstone of managing these dramatic cases.
