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.

At Retina Associates in Tucson, Arizona, Dr. Cameron Javid treats patients with a variety of retinal disorders. Frequently, Dr. Javid and the other physicians at Retina Associates assist patients with retina detachment.
The retina is a crucial element of the eye that converts light into signals that travel to the brain. If the retina does not work properly, people often experience blurred vision. However, retinal detachment is a more serious condition wherein the retina moves from its typical position at the back of the eye. Without proper treatment, this condition frequently leads to blindness.
Fortunately, there are a number of surgical treatments available to fix a detached retina. In the scleral buckling procedure, a physician secures a flexible piece of silicone rubber to the affected region of the eye, which creates an slight indentation in the eye wall and alleviates the tearing and detachment of the retina. Retina specialists may also recommend that a patient undergo pneumatic retinopexy, a procedure in which a physician injects a gas bubble into the eye to move the retina back into place. Following the procedure, the patient must hold his or her head in a specific position until the eye re-absorbs the gas bubble. This will ensure that the bubble does not become displaced and allow the retina to reattach. Vitrectomy surgery is a microsurgical procedure where the Surgeon places 3 small self sealing incisions approximately 1/2 mm wide and working with an operating microscope the surgeon can remove the vitreous, re attach the retina and treat the tears with laser or cryotherapy then place a gas bubble or silicone oil in the back of the eye to allow the retina to heal.
