[Double disinsertion of inferior and medial rectus muscle after injury. A case report].

We report a rare case of double disinsertion of inferior and medial rectus muscles of the left eye. After injury, the patient presented ocular ascension. The eye's position made the clinical examination difficult. The patient underwent two surgical treatments to find and reattach the deficient muscles. In spite of a laborious search, we obtained a good anatomic result. Oculomotor disorders require orthoptic training. To avoid diagnostic errors and to reduce oculomotor after effects, vigilance is required during examination.
