enucleation
Pronunciation: ee-nuk-lee-AY-shun
Surgical removal of the entire eyeball while preserving the extraocular muscles and orbital tissues.
Full Definition
Enucleation is a surgical procedure involving complete removal of the eyeball from the orbit while maintaining the integrity of extraocular muscles, eyelids, and orbital fat. In ocular oncology, this procedure is typically reserved for large intraocular tumors that cannot be treated with globe-preserving methods, cases with extensive tumor involvement, or when there is high risk of metastasis. The procedure is usually followed by placement of an orbital implant and eventual fitting of a prosthetic eye. Modern surgical techniques focus on preserving orbital volume and optimizing cosmetic outcomes.
Usage
Usage note: Distinguish from evisceration (removal of intraocular contents) and exenteration (removal of entire orbital contents).
