DIABETIC RETINOPATHY
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:
    • 12 mths for normal or minimal NPDR
    • 6-12 mths for mild to moderate NPDR w/o CSME & inactive/involuted PDR w/o CSME
    • 2-4 mths for mild to moderate NPDR w/ CSME, severe NPDR, non-high-risk NPDR, high-risk NPDR & inactive/involuted PDR w/ CSME

Post-op Follow-up

  • 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 w/ iris examination
    • Intraocular pressure (IOP) 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
    • Peripheral retina & vitreous examination, when indicated
