Surgery for Complete Vertical Rectus Paralysis Combined with Horizontal Strabismus

Figure 2

APRMT combined with horizontal muscle recession-resection (using paralysis of the superior rectus muscle as an example). Step  1: the medial rectus muscle and lateral rectus muscle were divided into 2 parts. Step  2: the upper one-half of the medial rectus muscle and lateral rectus muscle was shortened. Step  3: the shortened medial rectus muscle and lateral rectus muscle were transposed to the insertion of the superior rectus muscle on the nasal side and the temporal side. Step  4: recession-resection of the lower one-half of the medial rectus muscle and lateral rectus muscle was performed, and the ends of the recessed and resected muscles were aligned with the 2 original ends.
