|
Purpose: To report the good surgical results of multiple ruptured rectus muscles with avulsion of the optic nerve.
Case summary: A 39-year-old male patient underwent surgical exploration after rupture of the inferior and medial rectus muscles and avulsion of the optic nerve. The disinserted muscles were attached at the primary insertion site, and a served optic nerve was not found. Six months after the injury, the patient had orthotropia in the primary position without ischemia of the anterior segment.
Conclusions: In rare instances, blunt trauma can result in optic nerve avulsion with ruptured inferior and medial rectus muscles. Surgical treatment can result in a favorable outcome.
