Ocular Motility Abnormalities

Chapter

Abstract

Highly myopic strabismus is a rare acquired ocular motility disorder that affects highly myopic adults. The axial length of the eye frequently exceeds 30 mm. The eye movement is mechanically restricted in both abduction and supraduction, resulting in esotropia and hypotropia. In the most advanced form, strabismus fixus, the affected eye is so tightly fixed in an esotropic and hypotropic position that no movement in any other direction is possible even passively. MRI reveals that the globe is dislocated out from the muscle cone through the space between the superior and lateral rectus muscles. A surgical procedure to unite the muscle bellies of the superior and lateral rectus muscles is effective on improving both abnormal ocular motility and eye position.

The influence of myopia on concomitant strabismus is also briefly discussed.
