DIABETIC RETINOPATHY
Treatment Guideline Chart
Diabetic retinopathy is an abnormality of the microvasculature of the retina that occurs to almost all patients with chronic diabetes mellitus.
It is one of the leading cause of blindness worldwide and principal cause of impaired vision in patients aged 25-75 years of age.
The abnormality causes microaneurysms, retinal hemorrhages, lipid exudates, macular edema & neovascular vessel growth that may lead to blindness.

Follow Up

  • The follow-up interval recommended for the following DR severity:
    • 1-2 years in patients with no apparent DR or minimal NPDR and without DME
    • 6-12 months for mild NPDR without CSME
    • 3-6 months for moderate NPDR
    • <3 months for severe NPDR
    • <1 month for PDR
  • Recommended follow-up interval for patients with DME on initial screening:
    • 2-6 months for noncentral-involved DME
    • 1-3 months for central-involved DME

Post-op Follow-up and Follow-up After Initial Screening

  • A history of the changes on the following should be documented:
    • Symptoms
    • Glycemic status (HbA1c)
    • Systemic status (pregnancy, blood pressure, serum cholesterol, renal status)
  • Follow-up exam should include:
    • Visual acuity
    • Slit-lamp biomicroscopy with iris examination
    • Intraocular pressure determination
    • Gonioscopy (if iris neovascularization is suspected or present or if IOP is increased)
    • Stereoscopic examination of the posterior pole after dilation of the pupils
    • OCT when necessary
    • Peripheral retina and vitreous examination, when indicated
