Pronunciation: VIT-rek-toh-mee
Surgical removal of the vitreous gel from the eye's posterior chamber to treat retinal disorders.
Full Definition
Vitrectomy is a microsurgical procedure involving the removal of vitreous humor from the posterior segment of the eye. The surgery is performed using specialized instruments inserted through small gauge incisions in the pars plana. Common indications include diabetic retinopathy, retinal detachment, macular holes, and epiretinal membranes. The procedure may involve additional techniques such as membrane peeling, endolaser photocoagulation, or gas/oil tamponade.
Usage
Usage note: Distinguish from vitreous biopsy, which involves sampling rather than complete removal.
