Vascular microdissection in strabismus surgery.

Microdissection of the muscular vessels allows recessions, resections, or transpositions of the recti muscles without interrupting the blood flow to the corresponding anterior ciliary arteries. This avoids postoperative impaired blood flow to the anterior segment and may play a role in preventing anterior segment ischemia syndrome. The use of a fine-hooked cannula and microscissors, in addition to the usual strabismus surgery instruments, is described.
