Definition / Description

|
(1) |
Membrana limitans interna
|
The membrana limitans interna is the
retinal layer located nearest to the centre of the
eyeball - in contact with the hyaloid
membrane of the vitreous
humour. |
|
(2) |
Stratum opticum
|
The stratum opticum is the extension of the optic
nerve and is at its thickest around the optic
disc, gradually reducing in thickness towards the ora serrata. |
|
(3) |
Ganglionic layer
|
The ganglionic layer is
a single layer of large ganglion cells stretching
across the retina except in the region of the fovea where
there are several ganglia deep. |
|
(4) |
Inner molecular layer
|
The Inner Molecular Layer consists
of a network of fibres connecting and
meshing together the dendrites of ganglion cells
with cells of the Inner
Nuclear Layer. |
|
(5) |
Inner nuclear layer
|
The Inner Nuclear Layer consists of
three different types of cells that are packed closely
together. |
|
(6) |
Outer molecular
layer |
The Outer Molecular Layer is a dense
network of tiny fibres extending from the processes
of cells of Inner
Nuclear Layer. |
|
(7) |
Outer nuclear layer
|
The Inner
Nuclear Layer contains sub-layers
of oval-shaped components called rod-granules and cone-granules. |
|
(8) |
Membrana limitans externa
|
In common with the Membrana
Limitans Interna, the membrana limitans
externa is formed from the Fibres
of Müller. |
|
(9) |
Jacobs Membrane
|
The Jacob's Membrane is composed of
two types of units, they are rods (which
are the more numerous to the two), and cones. |
|

|
Pigmentary layer
|
The pigmentary layer (or "Tapetum
Nigrum") is the most external - i.e.
the most distant from the centre of the eye, layer
of the retina. |
