The patient was given a prescription for a prismatic correction in his glasses. He was given 4 prism diopters base down in front of the left eye. This was placed in a trial frame in the office and was found to alleviate the diplopia in primary gaze. The option of strabismus surgery in the future was also discussed. The plan is for him to use the prisms for several months and evaluate whether or not his symptoms are sufficiently alleviated. If he remains bothered by the diplopia, in spite of the prisms, and his degree of diplopia remains stable, then surgical correction will be considered.
