The term Sphincterotomy has two medical
meanings, one of which concerns an
ophthalmic procedure. They are:
- Non-ophthalmic definition:
The term sphincterotomy can be used to refer to the
surgical division (i.e. cutting/parting) of any sphincter muscle (that
is, a specialized ring of muscle that surrounds an orifice such as the
anus). In this case, a sphincterotomy usually involves
only partial, rather than complete, division of the muscle.
- Ophthalmic meaning:
In ophthalmology the term sphincterotomy refers to
surgical removal of part of the iris
of the eye.
