What type of diabetes eye disorders exist?
There are two types of retinal alteration in diabetes that can lead to blindness and are macular edema (accumulation of fluid and lipids in the central part of the retina) and proliferative DR (which produces intraocular hemorrhages, retinal detachments and glaucoma neovascular).
Diabetic retinopathy can only be prevented with an early diagnosis, which is performed by an ophthalmologist within a routine examination, in which it is recommended to dilate the pupil, although there are other tests that can help with diagnosis and treatment, such as fluorescein angiography ( injecting a dye into a vein of the arm), ocular ultrasound or OCT (optical coherence tomography).

Regarding the treatment of retinopathy, it will depend on the degree of affectation that each patient has, being of crucial importance the good control of the metabolic state, by the team that takes care of their diabetes. The therapeutic modalities, once the DR is established are intravitreal injections (antiangiogenic and corticosteroids), for diabetic macular edema, LASER and intraocular surgery (vitrectomy), which in many patients must be performed several times, until achieving control of your eye complications.
