Rectus muscle flap tear as an independent cause of restricted motility.

Author information

Department of Ophthalmology, Mount Sinai School of Medicine, New York, New York, USA.


Most published cases of rectus muscle flap tear have been associated with orbital trauma of various degrees of severity. When they accompany an orbital fracture, however, it is difficult to determine whether the flap tear is merely an incidental additional finding or a major contributing cause of the resulting restriction. How to treat the flap itself remains an open question. We report a 24-year-old man with an inferior rectus muscle flap tear caused by direct laceration of the muscle. The major finding was a "reverse leash" vertical restriction. Discarding the flap instead of reattaching it did not prevent a successful result. Our case supports the proposition that rectus muscle flap tear can be a restriction-producing entity.
