The
department of RETINA-VITREOUS dedicates to exploration,
diagnostic and treatment of diseases of the section of rear eye.
VITREOUS: It is situated between lens and retina. Its work is an
inner support of retina and due to its transparency it allows the
light to be transmitted.
RETINA: Is a neurosensorial tissue that internally covers the eye
bulb. Its work is to obtain light and to transmit the information
to the brain through the optic nerves.
Diseases such as diabetes and arterial hypertension affect all the
blood vessels, including those of the retina, which could lead to
loss of vision.
It is important to explore the back of the eye for early diagnostic
if the eye has been affected in these cases, and to avoid its development
and also to study the general state of the disease.

The
age related macular degeneration (ARMD) affects macula, which is part
of the retina that obtains the central vision and chooses colours.
We can’t forget that in our area it is now the most frequent
cause of nor reversible blindness, so that an early treatment is very
helpful. See NEWS.
The Cantabrian Institute of Ophthalmology has the most modern techniques
and the best experience to diagnose and treatment of the retina and
vitreous pathology from an exploration of the back of the eye, ecography,
electrophysiology, angiofluoresceingraphy, laser, up to more complicated
techniques as the vitrectomy and endoocular surgery.

The most frequent retina detachments are:
1.- Regmatogenous: produced by degeneration, holes or scratches
in the most peripherical parts of the retina, where it is thinner.
These types of detachments are frequent in great myopia, where the
size of eye increases, which produces a tension in retina that together
with disorganization of vitreous helps the detachment. These changes
can be observed in the back of the eye, which makes this an ideal
technique for it’s early diagnosis and avoid possible complications.
2.- Tractional: normally are second effects of diabetes due to the
proliferation of the fibrous tissue that accompanies the neovascular
response and produce traction force between vitreous and retina.
It is also produced by inflammation or traumatic phenomenons.
3.- Mixed: are detachments due to joint factors of degeneration
and traccionals.
To avoid the progression of the retinal detachment,
the Institute counts on photocoagulation techniques with laser (Argon/Diode),
which allow to fix the retina, creating sticky healings. The classic
escleral surgery of the detachment brings closer the retina to the
wall of bulb thanks to external implants of different materials.
In special causes it is realised by a gas. The tractional or mixed
detachments are solved by vitrectomy, which allows the extraction
of vitreous and solving subretinian membranes.
