- 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.
