title: Acquired divergent strabismus: presumed metastatic gastric carcinoma to the medial rectus muscle.
abstract: A patient with rapidly progressive metastatic gastric carcinoma developed diplopia and diminished adduction of the right eye. The right medial rectus muscle belly was enlarged, as shown by computed tomography. This case is unusual, because gastric carcinoma comprises only 1% of orbital metastases and less than 5% of all orbital metastases localize to extraocular muscle.
