Purpose: To describe a new eye muscle surgical technique and its outcome in a small series of patients. METHODS AND STUDY: The Foster augmented rectus muscle transposition procedure, which utilizes posterior "lateral" fixation sutures [retroequatorial scleral myopexy parallel and adjacent to the lateral rectus muscle] to obtain greater effect from the transpositions, is modified, to preserve ciliary vessels, by doing only a partial 75-80% transposition of the rectus muscles, preserving and leaving behind a small portion of the muscle containing a ciliary vessel.
Results: In five patients in whom preserving ciliary vessel supply was particularly important, the procedure produced results in improving binocular alignment and motility equal to that of the unmodified Foster augmented transposition. There were no complications or undesirable results.
Conclusion: The modified ciliary vessel preserving procedure can be applied in most cases and may be especially useful in those where this is a high likelihood of additional eye muscle surgery being necessary in the future.
