Scleral support surgery for pathologic myopia.

Pathologic myopia is the seventh leading cause of blindness in the US and two percent of Americans have the disease; Canadian statistics are not available. Pathologic myopia involves elongation of the eyeball and scleral support surgery aims to control the progression of this elongation. The most commonly used technique involves placing a strip of sclera from a donor eye around the eyeball to prevent further stretching. Due to variable trial designs and variable patient characteristics, this review determined there is insufficient evidence to establish the clinical efficacy of this procedure. More robust evidence is required, using standardized techniques and standardized outcome measures, before a meaningful evaluation of scleral support surgery can be conducted.
