Posterior fixation is a procedure in which a rectus muscle is sutured to the sclera far posterior to its insertion. The result is weakening of the muscle in its field of action with little or no effect on the alignment in primary position. This procedure is particularly useful for treatment of incomitant strabismus. A similar effect may be achieved, at least for medial rectus muscles, by fixation to the muscle pulley.
