superior oblique muscle The superior oblique muscle is a muscle in the orbit that causes the eye to look downwards when it is already directed medially (looking towards the nose). It is the only muscle supplied by the trochlear nerve. The superior oblique loops through a pulley like structure (the trochlea) to get the desired movement. "superior oblique muscle." Wikipedia.

Here are SOM related links to abstracts, articles and other citations of material that are informative. Please share these references with your doctor. It is important to note that these resources are here only because the sources have been generous in giving us permission to link to the information. Many resources do not allow us to link directly to the document, but permit a link to their main/home page. In those cases, instructions will accompany the link information. For those of us with dial-up connections, this can certainly be more work, but it cannot be avoided.

Name of the source, as well as Volume, Issue and page numbers are included so that you will be able to find the information even if (most likely 'when') the journal revamps their website and the link stops working.
