Giant orbital cyst as a complication of a slipped medial rectus muscle.
A 61-year-old woman presented with painless swelling in the right medial orbit. There was a history of complicated squint surgery at 9 years of age, with a slipped right medial rectus and subsequent exotropia. A retention cyst in the Tenon's capsule of the slipped medial rectus was confirmed by magnetic resonance imaging.
