Case Study: Treatment of Adult-onset Constant Esotropia with Lenses, Optometric Vision Therapy and Prisms

There are few documented cases, and no cases with a video journal recording a successful outcome from non-surgical treatment of adult- onset constant esotropia. Resolving diplopia caused by sudden onset esotropia is typically achieved through the application of prisms, or surgery. Surgery can resolve the diplopia and significantly reduce the strabismic angle, sometimes entirely. The application of prisms can resolve the diplopia but not alter the strabismic angle . Optometric vision therapy as a treatment, with or without the use of compensatory prisms, is rarely offered.
