Management of Strabismus Following Orbital Fracture Repair

Correspondence: Requests for reprints should be addressed to: Natalie Kerr, M.D., 956 Court Ave., Suite D228, Memphis, TN 38163.

Strabismus is common following orbital fracture repair. Direct trauma to the orbital contents, including the extraocular muscles and adnexa often results in disturbances of motility. The most common muscle injured is the inferior rectus, followed by the medial rectus. Both weakness and/or restriction of these muscles can occur, resulting in diplopia and/or loss of binocularity. Resultant diplopia is often incomitant and not correctable with prisms. Surgical approaches for repairing strabismus after orbital fracture repair are reviewed in this paper. A multiplicity of factors must be taken into consideration in the planning of strabismus repair to achieve a satisfactory outcome. With proper planning, and reasonable expectations on the part of the patient and surgeon, significant improvement in binocular visual function can be achieved following orbital fracture repair.

Key words: strabismus, orbital fractures, surgery, diplopia
