Vitrectomy
Vitrectomy is a surgery to remove some or all of the vitreous humor from the eye.
Anterior vitrectomy entails removing small portions of the vitreous humor from the front structures of the eye—often because these are tangled in an intraocular lens or other structures.
Pars plana vitrectomy is a general term for a group of operations accomplished in the deeper part of the eye, all of which involve removing some or all of the vitreous humor—the eye's clear internal jelly.
Even before the modern era, some surgeons performed crude vitrectomies. For instance, Dutch surgeon Anton Nuck (1650–1692) claimed to have removed vitreous by suction in a young man with an inflamed eye. In Boston, John Collins Warren (1778–1856) performed a crude limited vitrectomy for angle closure glaucoma.
Options for anesthesia for vitrectomy are general anaesthesia, local anesthesia, topical anesthesia and intracameral lidocaine irrigation.[medical citation needed]
Each anesthesia technique has its advantages and disadvantages, and the selection of anesthesia will depend on various factors including the surgeon's and patient's choice, disease and additional surgical steps required.[citation needed]
Vitrectomy was originated by Robert Machemer with contributions from Thomas M. Aaberg Sr in late 1969 and early 1970. The original purpose of vitrectomy was to remove clouded vitreous humor—usually containing blood.[citation needed]
The success of these first procedures led to the development of techniques and instruments to remove clouding and also to peel scar tissue off the light sensitive lining of the eye—the retina—membranectomy, to provide space for materials injected in the eye to reattach the retina such as gases or liquid silicone, and to increase the efficacy of other surgical steps such as scleral buckle.
