Successful surgical repair of a ruptured medial rectus muscle accompanied with serous chorioretinopathy.

Introduction: Extraocular muscle trauma can occur blunt or penetrating injury. This report highlights medial rectus muscle rupture after trauma.

Methods: A 41-year-old male presented with double vision after hitting a wall while riding a bike.

Results: Initial examination revealed right exotropia with -3 adduction limitation. Systemic corticosteroids were given to relieve orbital edema. The right medial rectus muscle could be partially retrieved upon strabismus surgery. Postoperatively, the patient complained of blurred vision, and optical coherence tomography revealed serous retinal detachment near upper vascular arcade, which did not affect the macula. Serous elevation decreased upon tapering the corticosteroids.

Discussion: Rupture of the medial rectus muscle can occur after blunt trauma and can occasionally be treated by retrieving the muscle in the early posttraumatic period. However, it should be borne in mind that factors related to the treatment of or trauma itself may threaten vision, therefore meticulous follow-up is mandatory.
