Summary

Imaging of retinal morphological changes with time secondary to laser treatment as assessed with high definition optical coherence tomography (OCT). Furthermore changes in retinal function as an effect of treatment will be documented by visual acuity testing using ETDRS charts and microperimetry. The change in vascular leakage will be assessed by performing fluorescein angiography, flare counts will be performed monthly.

Conditions

  • Proliferative Diabetic Retinopathy
  • Macular Edema
