vitreous chamber

Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.


an enclosed space.
Chambers of the eye. From Dorland's, 2000.
anterior chamber the part of the aqueous humor-containing space of the eyeball between the cornea and iris.
counting chamber the part of a hemacytometer consisting of a microscopic slide with a depression whose base is marked in grids, and into which a measured volume of a sample of blood or bacterial culture is placed and covered with a cover glass. The number of cells and formed blood elements in the squares is counted under a microscope and used as a representative sample for calculating the unit volume.
drip chamber the expanded portion of intravenous tubing into which fluid falls, where the rate of flow can be monitored if necessary. See also intravenous infusion.
hyperbaric chamber an enclosed space in which gas (oxygen) can be raised to greater than atmospheric pressure; see also hyperbaric oxygenation.
ionization chamber an enclosure containing two or more electrodes between which an electric current may be passed when the enclosed gas is ionized by radiation; used for determining the intensity of x-rays and other rays.
posterior chamber that part of the aqueous humor–containing space of the eyeball between the iris and the lens.
vitreous chamber the vitreous humor–containing space in the eyeball, bounded anteriorly by the lens and ciliary body and posteriorly by the posterior wall of the eyeball.

The mean of right vitreous chamber depth measurement was not significantly different from the left one (P>0.05).
The depth of vitreous chamber of the globe in right side were mostly lesser than left one but have not signiicant statistically deference with them and these are unlikely to be of clinical significance.
This study was to characterize the normal ultrasound appearance and ocular biometry of vitreous chamber in the eye of cattle by using a widely available, general purpose scanner and this investigation will provide baseline information for the study of pathologic conditions affecting the eyes with an ultrasound unit commonly available to the veterinarian.
An enucleation was performed on the left eye, which contained an exophytic retinoblastoma that filled most of the vitreous chamber. On examination, the tumor was found to significantly invade the optic nerve with no invasion of the choroid.
Our findings contrast with the results of previous reports, which stated that adult women had shorter axial globe length, shallower anterior and vitreous chamber depth, and thicker lenses than adult men (WONG et al, 2001; WARRIER et al., 2008).
The ultrasound machine used during this research was calibrated to acoustic wave propagation velocities for ocular tissue of humans at 1,532m [s.sup.-1] for the anterior chamber, 1,641m [s.sup.-1] for the lens, and 1,523m [s.sup.-1] for the vitreous chamber (GORIG et al., 2006).
The results of this research showed that dimensions of anterior chamber, lens, vitreous chamber and axial globe length of adult goats did not differ between the genders.
