The retina is a layer of specialized cells inside the eyes; through it we obtain sharp images, colors and details of objects.
In diabetic patients, after several years of illness, even controlled, become a decrease of irrigation by the impairment of retinal blood vessels. The result of this is the formation of abnormal vessels that do not support the blood pressure with rupture, leading to internal bleeding in the retina and inflammation (swelling) of central retina, the macula. The end result is a gradual loss of visual function (blurring of images).
All people with Diabetes Mellitus are subject to this problem, but the disease does not manifest itself equally for everyone. Some cases are more serious and others less. Individual factors like genetic can explain this.
Clinical examination, angiography and OCT (optical tomography) helps to classify the lesions and propose the most appropriate treatment.
The most common treatment is the use of laser. It is performed by applications (sessions) outpatients.
Another form of treatment is vessels growth factors inhibitors drugs (anti-VGF) like bevacizumab (Avastin) and ranibizumab (Lucentis). It is of drugs that inhibit the formation of neovascular lesions and decrease the edema Retinal. However, not all cases can use these substances.
The surgery is also widely used as treatment.
Every eye treatments will be successful only if there is an efficient clinical control. Therefore, treatment should be undertaken with the collaboration of professionals from different specialties.
The guidance of an experienced retina specialist is the main factor to obtain the best result of existing treatments
