Superior Oblique Myomymia: Innervation of the extra ocular muscles, the lacrimal gland and the sensory nerves of the orbit. Note that the muscular superior oblique that runs forwards in the medial orbit becomes a tendon as it passes through the trochlea and then is purely tendinous as it inserts into the posterolateral part of the globe. It is this anterior tendon that is manipulated and operated upon with partial or total tenectomy. Contributed by Prof. Bhupendra C. K.

The muscle changes direction via the trochlea which is a pulley-like structure and passes under the superior rectus muscle and inserts posteriorly and temporally on the globe. Muscle action causes intorsion and depression of the eye. Patrick J. Lynch, medical illustrator
