The hyaloid membrane is a transparent
membrane that encloses the vitreous
humour, seperating it from the retina.
In front of the ora serrata (the area in which the retina terminates
as a jagged margin towards the front of the eyeball as it approaches the
ciliary
body) the hyaloid membrane is thickened by radial fibres and is called
the Zonule
of Zinn or (another name for the same thing, the zonula
ciliaris).
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".
For further detail about components of the human eye mentioned on these
pages, we recommend Gray's
Anatomy as one of the most informative yet inexpensive sources of
detailed information. |
