A surgical procedure that strengthens the superior oblique muscle by doubling over its loose tendon and securing it with a suture woven through the tendon base in a double figure-eight fashion. This shortens the effective tendon length, enhancing the muscle’s actions of depression, intorsion, and abduction. The superior oblique tuck is commonly performed to treat superior oblique palsy or paresis, correcting the associated hypertropia, excyclotorsion, and limited depression.
