INFERIOR OBLIQUE SURGERY FOR RESTRICTIVE STRABISMUS IN PATIENTS WITH THYROID ORBITOPATHY

Introduction: Thyroid orbitopathy is the most common cause of restrictive strabismus. Patients often present with vertical or horizontal double vision, or both, due to restriction involving most commonly the inferior and medial rectus muscles. Traditional muscle surgery involves release of the tight muscles. Previous literature has described a frequent need for secondary operations and an overcorrection incidence of up to 50%.
