vitreo-, vitre-, vitr- +
(Latin: glass; glassy; like glass)
This may be done because it has blood and scar tissue in it that blocks sight. An eye surgeon then replaces the clouded gel with a clear fluid.
3. Removal of the whole or part of the vitreous body in treating endophthalmitis, diabetic retinopathy, retinal detachment, intraocular foreign bodies, and some types of glaucoma.
Surgical procedures which may be used as part of modern vitrectomy surgeries
- Membranectomy: the removal of layers of unhealthy tissue from the retina with minute instruments; such as, forceps (tiny grasping tools), picks (miniature hooks), and visco-dissection (separating layers or tissue with jets of fluid).
- Fluid-gas exchange: the injection of gas into the eye; such as, sulphur hexaflouride or perflouropropane to hold the retina in place or to temporarily seal off holes in the retina. These gases disappear spontaneously once they have accomplished their purpose.
- Silicon oil injection: filling the eye with liquid silicon to hold the retina in place.
- Photocoagulation: a laser treatment to seal off holes in the retina or to shrink unhealthy, harmful blood vessels which grow in some diseases; such as, diabetes.
- Scleral buckling: the placement of a support positioned similar to a belt around the walls of the eyeball to hold the retina in a proper, attached position.
- Lensectomy: removal of the lens in the eye when it is cloudy (cataract) or if it is attached to scar tissue.
2. Relating to, resembling, or having the nature of glass; glassy.
3. Obtained or made from glass.
4. Of or relating to the vitreous humor.
5. Glasslike or hyaline; often used alone to designate the vitreous body of the eye.
The vitreous body refers to the transparent gel that fills the inner portion of the eyeball between the lens and the retina; also called, hyaloid body, humor cristallinus, and crystalline or vitreous humor.
2. The transparent gelatinous substance filling the eyeball behind the crystalline lens.
The vitreous humor contains very few cells; mostly phagocytes which remove unwanted cellular debris in the visual field), no blood vessels, and 99% of its volume is water with salts, sugars, and a network of collagen fibers with hyaluronic acid accounting for the rest; however, the vitreous has a viscosity two to four times that of pure water, giving it a gelatinous consistency.
Hyaluronic acid is a complex viscous substance that lubricates joints in the body and is present in connective tissue. It also plays a role in the healing of wounds.
2. Having the capability of conversion into glass.
3. The susceptibility of being formed into glass.
2. Capable of being turned into glass.
2. Having the characteristics or appearance of glass.
3. Of the nature of or resembling glass.
4. A description of any glassy, pyroclastic material containing at least 75% glass.
