What is Vitreous Surgery?
|
|
Vitreous is a gel like material that fills the back
of the eye and occupies about
4/5ths
of the eye ball. It is normally clear and
transmits light to the light sensitive retina. |

How does the vitreous become diseased? |
|
Diseases can affect the
vitreous alone
or the vitreous could be affected along with
the neighbouring structures.
Abnormalities in the vitreous could be
broadly in the form of opacities that block
the entry of light;
abnormal scar tissue that pulls on
the sensitive retina.
|
|
|
The commonest opacity of the
vitreous that blocks the light entry is
blood. Bleeding can occur into the vitreous due to
several diseases such as
diabetic retinal disease,
blunt or
penetrating injury to
the eye, occlusion of the
retinal blood vessels etc. |
|
|
|
Very often blood in the vitreous cavity
(vitreous haemorrhage)
is associated with variable amount of abnormal scar
on the retina and the vitreous. |
| |
|
Certain types of retinal detachment can be
associated with vitreous anomally. |
