  6. Protocol: Ophthalmology Exam Intervals for those with retinal disease
    1. Mild to moderate nonproliferative diabetic retinopathy
      1. No macular edema: Exams every 6-12 months
      2. Macular edema present: Consider laser photocoagulation
    2. Severe nonproliferative diabetic retinopathy
      1. Eye examinations every 2-4 months
      2. Consider laser photocoagulation
