[High myopia with esotropia fixus].
Most of the 19 cases of high myopia with esotropia fixus had the refractive error in childhood while esotropia fixus set in progressively during middle age. The eyeball was fixed in a position of marked adduction, and the forced duction test was positive. Electromyography showed normal innervation of the medial and lateral recti. Contracture of the medial rectus and thinning of the lateral rectus were observed during surgery. Histopathological examination revealed degeneration and fibrosis in the medial rectus. Etiology was not clear. Tenotomy of the medial rectus or that of the inferior rectus in addition, with fixation of the lateral rectus tendon to the lateral orbital rim produced satisfactory corrective results.
