The vitreous body at birth is homogenous with a finely striated pattern. With early aging the vitreous develops narrow transvitreal "channels". The cortex is denser than the centre with development. From adolescence, vitreous tracts form from anterior to posterior. These vitreous tracts are fine sheet-like condensations of vitreous. Named tracts
Others may be "coagula of the proteins of the vitreous gel, to embryonic remnants, or the condensation round the walls of Cloquet's canal" that exist in pockets of liquid within the vitreous. The first two sort of floaters may collect over the fovea (the center of vision), and therefore be more visible, when a person is lying on his or her back ...
Asteroid hyalosis is a degenerative condition of the eye involving small white opacities in the vitreous humor. [1] It is known to occur in humans, dogs, cats, horses, and chinchillas. [2] Clinically, these opacities are quite refractile, giving the appearance of stars shining in the night sky—except that ocular asteroids are often quite mobile.
Hyalocytes, also known as vitreous cells, are cells of the vitreous body, which is the clear gel that fills the space between the lens and the retina of the eye. Hyalocytes occur in the peripheral part of the vitreous body, and may produce hyaluronic acid and collagen fibrils , [ 1 ] [ 2 ] Hyalocytes are star-shaped (stellate) cells with oval ...
Most retinal tufts are stable and do not change over time. Due to the traction that is placed on the vitreous humor, the retinal tuft may change in shape. Retinal tufts increase the risk of a retinal tear or a detached retina, although the risk is not high- 1% of tufts are thought to lead to retinal detachment.
In women, menopause can speed up bone loss "due to the loss of the protective effects of estrogen on bones," Dr. Arashdeep Litt, an internal medicine physician with Spectrum Health, tells Yahoo ...
Moore's lightning streaks are lightning type streaks (seen to the temporal side) due to sudden head or eye movement in the dark. They are generally caused by shock waves in the vitreous humor hitting the retina or traction on the retina from fibers in the vitreous humor.
A former NASA commander has revealed that while piloting his private plane in Texas last summer he nearly had a collision with two mysterious “metallic, spherical orbs.”
