[8] [23] [24] In this technique, the vitreous gel is removed from the eye to relieve the pulling force on the retina. [8] [10] Any fluid behind the retina is drained, and tears are sealed with freezing or lasers. [8] [10] The removed vitreous is then replaced with either a gas bubble or silicone oil, which stabilizes the retina.

The vitreous (Latin for "glassy") humor is a gel which fills the eye behind the lens. Between it and the retina is the vitreous membrane. With age the vitreous humor changes, shrinking and developing pockets of liquefaction, similar to the way a gelatin dessert shrinks and detaches from the edge of a pan. At some stage the vitreous membrane may ...
Over time, it is common for the vitreous within the human eye to liquify and collapse in processes known as syneresis and synchisis respectively. This creates fluid-filled areas that can combine to form pockets of vitreous gel that are mostly liquid with very small concentrations of collagen .
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 ...
Intravitreal injection was first mentioned in a study in 1911, in which the injection of air was used to repair a detached retina. [6] [7] [8] There were also investigations evaluating intravitreal antibiotics injection using sulfanilamide and penicillin to treat endophthalmitis in the 1940s, yet due to the inconsistency of results and safety concerns, this form of drug delivery was only for ...
