WHEN JAMESON first presented his technique of recession, he primarily described a method of suturing a muscle ending directly to the sclera.* This gave more uniform results than simple tenotomy. He advised that after the incision of the conjunctiva, the "capsule" be buttonholed about 3 mm. from the belly of the muscle in the region of the equator. A strabismus hook was inserted into the buttonhole and slipped under the muscle. A second buttonhole was made on the other side of the muscle at a corresponding distance. The muscle then was undermined, and diverging "capsular" incisions were made, which were carried forward to meet the muscle at the outlines of its insertion. When the muscle was tenotomized, a "capsular" flap overlying the muscle was completed and allowed to retract along with the muscle.
There have been many modifications of the Jameson original procedure. For example, the angle and placement of
