A subconjunctival hemorrhage can often occur without any obvious cause or harm to the eye. A strong enough sneeze or cough can cause a blood vessel in the eye to burst. Hyphema is a result of blunt or penetrating trauma to the orbit that increases intraocular pressure, causing tears in the vessels of the ciliary body and iris.
The Marburg virus, which causes bleeding from the eyes, nose, and mouth, can be fatal in up to 90% of those infected ... It’s a close cousin of Ebola that’s been dubbed the “bleeding eye ...
Hyphema is the medical condition of bleeding in the anterior chamber of the eye between the iris and the cornea. [1] People usually first notice a loss or decrease in vision. [1] The eye may also appear to have a reddish tinge, or it may appear as a small pool of blood at the bottom of the iris in the cornea.

MVD, which is frequently fatal and is related to the much better-known Ebola virus, is sometimes known as "bleeding eye disease" because it damages people's blood vessels, causing them to bleed ...
A tear in the retina can allow fluids from the eye to leak in behind the retina, which causes retinal detachment. When this occurs, blood from the retinal blood vessels can bleed into the vitreous. [4] Retinal tear accounts for 11.4–44% of vitreous hemorrhage cases. [1]
