The retinopathy is the common denomination of any non- inflammatory pathology of the retina, the inner layer of the eyeball responsible for receiving and sending images of the eye to the brain. That is why the term encompasses a range of conditions, with the most common and known diabetic retinopathy, which occurs due to high blood glucose levels in these patients. The symptoms are not evident during the early stages of this type of retinopathy, which can lead to vision loss, so it is critical that diabetics undergo regular ophthalmological controls. Its main photocoagulation treatment involves a laser surgery to repair abnormal blood vessels that have been created in the retina. Lastly, if you have entered blood in the vitreous humor, the vitrectomy is used, a type of surgery used only if the bleeding has been very generous.
