PURPOSE: The purpose was to describe the medial rectus muscle elongation (MRE) procedure to treat very large-angle @entity5971 ( @entity5971 ) with surgery on a lower number of muscles. METHODS: Twenty @entity1 with very large-angle @entity5971 (more than 70 @entity1726 ) underwent the MRE procedure. In the MRE procedure, the muscle was split longitudinally into three parts. The wider central part was sutured with 6/0 vicryl and disinserted. The distal end of the peripheral parts (still attached to the original insertion), 7-9  mm away from the insertion, was sutured to the proximal end of the central part. At the end of the procedure, the distance of the @entity254 site from the insertion was named as the final elongation. The dose-response effect of the final elongation was calculated in bilateral MRE cases. The mean of the dose-response effect, obtained in the binocular surgery group, was used in the monocular surgery group to calculate the resection effect of lateral rectus (LR) muscle. RESULTS: Eleven @entity1 underwent bilateral MRE and nine @entity1 underwent unilateral MRE and LR muscle resection. The mean preoperative far and near deviation was 94.10        19.33 @entity1726 . The mean postoperative deviation was 14.60        18.07 @entity1726 for far and 14.50        18.23 @entity1726 for near deviation. In bilateral MRE cases, the mean dose-response effect of the elongation was 5.53        0.67 @entity1726 /mm for far and 5.58        0.69 @entity1726 /mm for near deviation. The mean LR muscle resection effect was 6.41        1.99 @entity1726 /mm for far and 6.28        1.93 @entity1726 /mm for near deviation. CONCLUSION: The MRE procedure seems an acceptable method to treat very large-angle @entity5971 with surgery on a lower number of muscles.
