Retinal Vascular Diseases
Subretinal hemorrhage. The area of hypofluorescence in the fluorescein angiogram is consistent with blockage of normal choroidal filling. Retinal vascular filling appears normal.

  • Clinical features:
    • Usually appear as dark-red, amorphous hemorrhages
    • Situated deep to the retinal vessels and located under the retinal neurosensory level or RPE
  • Fluorescein angiography demonstrates:
    • Area of hypofluorescence, which is consistent with blockage of underlying details in areas of hemorrhages
    • Normal fluorescence of surrounding choroidal filling and overlying retinal vascular perfusion
  • Associated conditions include: choroidal neovascular membranes (CNVM), trauma that lead to choroidal rupture, macroaneurysms or exudative age-related macular degeneration.
