PASSAGE of a bridle stay suture beneath each rectus muscle insertion is done to control the eye in most operative procedures for retinal detachment. This report describes an instrument which has proven useful in the rapid passage of these sutures. Two modifications of the instrument have been fashioned from ordinary muscle hooks (Fig 1). In both the tip of the muscle hook was flattened to a thickness of about one third millimeter. In a right-angle model, an oval hole, 2×1 mm, was bored near the tip of the instrument to accommodate either a stay suture or a No. 40 silastic band (Fig 1). Another model with a 1 mm round hole at the slightly pointed tip was designed for the passage of stay sutures only. An S-shaped curve in the shank permits easier exposure of the instrument tip once it is passed beneath the muscle. A No. 4-0 stay suture
