Abstract

Anterior segment ischemia(ASI) may be caused by a detachment of the rectus muscles from the globe. The interruption of the anterior ciliary artery by the detachment of rectus muscles causes a subsequent hypoperfusion to the anterior segment. ASI occurs more easily after surgery on the vertical rectus or after detachments of two or more adjacent rectus muscles. We experienced two patients with ASI after performing muscle surgery on them for lateral rectus muscle palsy caused by a traffic accident. A 5-year-old-male developed keratitis and uveitis following a Hummelsheim operation in combination with a lateral rectus resection in his right eye. A 51-year-old female showed keratitis, uveitis and pupilary distortion after a Knapp procedure combined with a lateral rectus tucking in her right eye. Both patients recovered without any complications.
