Retinopathy is the common name of any non-inflammatory disease of the retina, the innermost 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, the most common and known diabetic retinopathy, which occurs due to elevated 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 important that diabetics undergo regular eye examinations. Its main treatment is photocoagulation, laser surgery to repair abnormal blood vessels that have been created in the retina. Finally, in the case of blood that has entered into the vitreous humor, a vitrectomy is used, a type of surgery used only if the bleeding has been very generous.
