Preretinal haemorrhage and Flame shaped haemorrhage

Preretinal haemorrhage an Flame shaped haemorrhage

Preretinal (Subhyaloid) hemorrhages:

  • Clinical features:
    • Occur either in the level of subhyaloid space between posterior vitreous face and retina or under internal limiting membrane.
    • Localized vitreous gel detachment may occur.
    • Horizontal blood level or boat-shaped hemorrhage is usually apparent, which obscures the underlying retina.
  • Fluorescein angiography demonstrates blockage of underlying details in areas of hemorrhages.
  • Underlying causes include retinal tear, bleeding from neovascularization, rupture of the internal limiting membrane, hypertensive retinopathy, posterior vitreous detachment, and vascular occlusion.

Flame shaped haemorrhage:

  • A form of intraretinal hemorrhages
  • Hemorrhage from the superficial capillary plexus.
  • Feather- or flame-shaped¬†hemorrhages with indistinct borders indicate that blood accumulates at the level of nerve fiber layer, reflecting the structure of the nerve fiber layers that run parallel to the retinal surface.
