Amaurosis after blepharoplasty is a complication which is considered to be rare, but which nevertheless deserves extreme attention. Although various hypotheses have been proposed (and sometimes proved) its etiopathogenesis is still uncertain. The observation of a case of temporary loss of vision after blepharoplasty, which promptly regressed after medical therapy, led us to a revision of the most common causes of amaurosis, and to formulate, for this case, the etiopathogenetic hypothesis of acute glaucoma, which has already been reported in scientific literature, but without any case report.
