title: Incidental hypoglobus: primary amyloidosis of the superior rectus.
abstract: A 69-year-old man who presented with incidental hypoglobus was found to have an isolated superior rectus mass. Diagnosis of primary amyloidosis of superior rectus was made on incisional biopsy and negative systemic work-up. This is an unusual manifestation and site for amyloidosis and should be a differential of any extraocular muscle mass.
