We appreciate the interest demonstrated in our article, “Extraocular Muscle Enlargement in Growth Hormone-Secreting Pituitary Adenomas.” AJNR Am J Neuroradiol 2022;43:597–602. It is correct that dedicated orbital imaging was not performed in this series of patients secondary to the retrospective nature of the study. That would be an excellent next step in the further analysis of the changes in extraocular muscles in this clinical scenario. The images analyzed were not all from dedicated pituitary imaging. Many of the images analyzed were from the preoperative MRIs and from MRIs used for radiation planning. The measurement of the extraocular muscles was the greatest short axis diameter of the muscle (Figure).
