The Vitreous Humour (also known as the
Vitreous
Body) is located in the the large area that occupies approx. 80% of
each eye in the human body. Note that this is spelt "Vitreous
Humor" in textbooks that use American spellings - the meaning is
the same.
The vitreous humour is a perfectly transparent thin-jelly-like
substance that fills the chamber behind the lens
of the eye - click
for diagram. It is an albuminous fluid enclosed in a delicate transparent
membrane called the hyaloid
membrane.
There is a canal called the canal of Stilling running
through the centre of the vitreous humour from the entrance
of the optic nerve to the posterior surface of the lens. This is filled
with fluid and lined by a prolongation of the hyaloid membrane.
The subject of visual (also known as "physiological") optics
is a key component of many courses within the fields of both biology and
physics. It is also an essential consideration in the design of displays
and control units used in many applications from televisions and mobile
telephones to advanced aircraft. In the context of engineering "visual
optics" is one of several medical and psychological topics in the
important area of "Human Factors". |
