  1. Values are presented as average (standard deviation).
  2. MCT, mean choroidal thickness of 6 mm scan area; P val: P value of Wilcoxon singed rank test between that visit and baseline; CVI, choroidal vasculature index represents the ratio of the choroidal vessels (lumen volume) relative to the entire choroidal volume within 6 mm scan area.
  3. Vessel Density is defined as the total length of perfused vasculature per unit area in a region of measurement.
  4. Perfusion Density is defined as the total area of perfused vasculature per unit area in a region of measurement.
  5. * asteriks indicates P value less than 0.05, bold indicates values with significant defference.
