Fig. 17. “Hangback” technique for superior oblique tendon recession. Left superior oblique tendon has been secured with a double-armed polyglactin suture, which is then passed through the sclera at the anterior half of the original insertion. Tendon is shown near its normal anatomic position, but it will be allowed to retract under the superior rectus muscle (arrow) before the suture is tied. The superior rectus muscle has been engaged on a Jameson muscle hook to hold the eye in infraduction.
