• Vision test and eye pressure measurement.
  • Retinal examination with dilated pupils: This allows for a precise assessment of the vessels into the periphery.
  • Optical Coherence Tomography (OCT): This painless cross-sectional imaging of the retina detects swellings (edema) at a stage when they are not yet visible during a normal examination.
  • In cases of advanced changes or bleeding, an ultrasound examination of the eye is sometimes necessary.
