Loop Myopexy Surgery for Strabismus Associated with High Myopia

Figure 2

Flow diagram of the selecting process of surgical procedure. MRI or CT scan of the orbit before surgery can give a clear demonstration of the rectus muscle paths. If there is an absence of alteration in muscle paths, both Yokoyama’s procedure and traditional recession-resection surgery have been recommended in some studies. In patients with abnormality in muscle paths, if contracture of the MR muscle is found, the MR recession is recommended together with the union of the LR and SR. If there is no evidence of MR contracture, the MR recession can be staged in a second surgery when the union of LR and SR is not sufficient to correct the abnormal muscle paths.
