Superior oblique tendon expansion in the management of superior oblique dysfunction.

Traditional superior oblique weakening procedures may be unpredictable and lead to superior oblique underaction. The use of 240 retinal band as a spacer to lengthen the superior oblique tendon has been proposed as a more controlled approach than superior oblique tenotomy and related procedures. The use of this technique is reported in a patient with diplopia following an orbital floor blow out fracture, and in a child with Brown's superior oblique tendon sheath syndrome.
