Scleral show.

"Scleral show" is an anatomical condition in which the sclera area is visibly exaggerated due to constitutional, evolutive, or endocrine etiology. It can also occur because of iatrogenies, and is considered one of the most complex blepharoplasty complications. Its evolution and poor response to treatment are questionable. The defect is not always linked to an ectropion, and the basic differences between the two are explained. During blepharoplasties, in order to avoid iatrogenic "scleral show," among other complications, one should take special precautions with the quantity and the exact location of the tarsal portion of orbicularis oculi muscle to be resected.
