Adjustable sutures of the vertical recti.

Fifty patients were operated for vertical strabismus problems using the adjustable suture technique. Eighty-two vertical recti muscles were either adjustably recessed or resected. the surgical decisions and muscle placement placed emphasis on the cover test plus evaluation of muscle stiffness rather than the traditional prism diopter-millimeter correlations. It was necessary to adjust 26% of the muscles postoperatively.
