Patients with similar proliferative diabetic retinopathy without high risk characteristics receive laser therapy in both eyes and intravitreal Bevacizumab injections in one eye. For the Bevacizumab injections, numbing drops, antibiotic drops, and drops to dilate the pupil, and possibly and anesthetic injection, are put in the eye before the medicine is injected into the vitreous. Patients return for follow-up visits 1 day, 1 and 4 weeks after the injection, and then 3 and 6 months. Patients whose condition does not improve may undergo new evaluation.
