The excess of sugar (glucose) in the blood causes important injuries in the blood vessels of all the organism.
These injuries are pronounced with special intensity at level of the

Signs and symptoms.
retinopatía is divided in two types:
retinopatía, in which the vision diminishes by an alteration of the
zone of the denominated
The loss of vision is relatively fast, and continuous.

retinopatía, in which the vision diminishes by the appearance of hemorrhages and new blood vessels inside the vitreous cavity (later camera of the eye)
The loss of vision takes place by stages, according to is taken place the hemorrhages, noticing blurred zones in the field of view, that are extended in size and number.
It causes loosenings of

In some patients,

retinopatía is diagnosed of precocious form, effective methods exist to avoid the
The treatment of the
retinopatía is based in the first place on the strict control of the numbers of glucemia. In order to obtain this objective, it is fundamental the work of the attending physician and / or endocrinólogo, as well as the collaboration of the patient.
Nowadays, the most effective technique stops of the treatment of the
retinopatía is the fotocoagulación with Argon laser.
The treatment with laser must be precocious possible and is able to stop the
of the retinopatía.
Diverse techniques of fotocoagulación exist and the ophtalmologist will seat the indication depending on the situation of
In many cases it is necessary to make several sessions of laser to complete the treatment.
Another possibility is the Vitrectomía, technical surgical in which the vitreous humor is replaced, gel that fills up the later part of the eye, by an artificial polymer) that is used for example when the vitreous hemorrhages are not reabsorven after
