摘要：

Retroequatorial fix-tion of a rectus muscle by means of nonabsorbable scleral sutures weakens this muscle in its primary field of action without disturbing the balance with its antagonist in other positions of gaze. This procedure has been employed in patients with dissociated vertical deviations, nystagmus compensation (blockage) syndrome, double-elevator paresis, nonaccommodative convergence excess, and Duane's retraction syndrome. Complications were not encountered, but the operation was ineffective in some patients and reoperation became necessary.
