Abstract

The upshoot or downshoot that occurs when an eye is adducted in Duane's retraction syndrome is believed to be related to a taut lateral rectus muscle. When an eye is adducted, the lateral rectus muscle is slipped over the globe, producing this abnormal eye movement. Seven patients with Duane's retraction syndrome demonstrated this findings and underwent an Y-splitting operation on the lateral rectus muscle. Y-splitting and recession of the lateral rectus muscle is safe and simple procedure. All 7 patients demonstrated markedly decrease in the upshoot or downshoot after surgery.
