A case of relief of depression of the lower lid following the reinsertion of an accidentally tenotomized inferior rectus muscle is presented here for several reasons. It demonstrates complications which could occur after an attempt at tenotomy of an inferior oblique muscle and puts one on guard when performing such an operation. Further, it presents a suggestion for management of future cases in which dysfunction of the lower lid is associated with or caused by a defect in the inferior rectus muscle.
The inferior oblique muscle1 arises from a shallow depression in the anteromedial corner of the floor of the orbit. It passes laterally and backward as a flat band beneath the inferior rectus muscle, to which it is united by its fascial sheath, and finally attaches to the posterolateral aspect of the globe. The inferior rectus muscle1 runs above the orbital floor. As it crosses the
