A Study of Horizontal Strabismus Surgery: Is Medial Rectus Surgery More Effective on Near Deviation?
We used to believe that medial rectus surgery was more effective on near deviation than on distant deviation, and conversely lateral rectus surgery was more effective on distant deviation. Therefore, an unequal amount of unilateral recession and resection, bimedial rectus recession or bilateral rectus resection has often been per formed on non-basic type horizontal strabismus (Awaya, 1985; von Noorden et al, 1986). However, no statistical study has ever clearly demonstrated the propriety of these relationships. Our purpose is to clarify how each recession and resection of rectus muscle influences the surgical result.
