Made up of four doctors of ophthalmology, including Dr. Cameron Javid, Retina Associates treats patients in Tucson, Arizona. The practice offers a range of surgical procedures, including one that reduces loss of vision due to diabetic retinopathy.

Diabetic retinopathy impacts people with diabetes mellitus, a condition that harms blood vessels in the retina because of high sugar levels. The illness comes in two forms, non-proliferative diabetic retinopathy (NPDR) and proliferative diabetic retinopathy (PDR). NPDR, which causes secretion of blood and fluid in the retina, typically does not affect vision until macular edema or ischemia becomes an issue. Macular edema does not eliminate peripheral vision; rather, it creates swelling of the macula which results in vision loss. Macular ischemia closes the capillaries, thus causing blurry vision.

PDR derives from the closure of retina blood vessels. Because the eye does not receive enough blood supply, it begins neovascularization, a formation of abnormal new blood vessels that appear on the surface of the retina or optic nerve. Wrinkling or detachment of the retina can occur from scar tissue. In addition, there is risk of a vitreous hemorrhage, which in severe cases, will block out all vision.
