[An unusual case of major restriction of eye motility: severe myopia].

Severe restrictive disorders of ocular motility are rarely described in high myopia. Their cause is still unknown. Several theories have been suggested: structural changes in the ocular muscles, sixth-nerve palsy or an elongation of the ocular globe. We report the case of a 44 years old man with high myopia of the left eye and disturbed ocular motility. Medical imaging techniques (echography, CT, MRI) allowed us to objectify the cause of ocular motility problem.
