Sub-Hyaloid Hemorrhage!

-Accumulation of blood in the subhyaloid or retrohyaloid space i.e. between the ILM and posterior hyaloid causing a localised detachment of the vitreous from the retina.

-The hemorrhage is sharply demarcated because the hyaloid is attached in the region surrounding the hemorrhage.

-It begins as a circular shape and later becomes crescentic with a straight upper margin due to the effect of gravity giving it a boat shape.

-Source of blood: Retinal blood vessel capillaries.

-Severe vision loss if it occurs in the macular area.
