The term sphincterotomy has two medical meanings, one of which concerns an ophthalmic procedure.
- 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.
