Periocular
Pronunciation: peh-ree-OK-yoo-lar
Relating to the tissues and structures immediately surrounding the eye, used as a precise anatomical descriptor in aesthetic procedural documentation.
Full Definition
The term 'periocular' is an anatomical adjective that encompasses the eyelids, eyebrows, tear trough, and the immediately adjacent skin surrounding the orbital rim. In aesthetic dermatology, it is used to describe treatments, complications, and photographic documentation zones in the periocular region. Editors must distinguish 'periocular' from 'periorbital': 'periorbital' refers specifically to structures around the orbit (the bony cavity), while 'periocular' is broader and relates to structures around the visible eye. Both terms appear frequently in aesthetic literature and are often used interchangeably, but precision is required in clinical and regulatory documents.
Usage
Usage note: 'Periocular' (around the eye) and 'periorbital' (around the orbit/bony cavity) are not strict synonyms; use 'periocular' when referring to soft tissue and skin surrounding the visible eye.
