Hello and welcome to HCM
The cause of blak eye has to be known. Is there any history of trauma to the eye, nose or base of skull?
All these forms of injury
cause blackening of eye and this is due to accumulation of blood in soft tissues around the eye.
that you are observing in the white part (Sclera) of the eye is also due to the trauma. Trauma has caused rupture of thin walled blood vessels in the sclera.
This congestion will clear away in few days.
Get a CT scan
of head and face region to rule out any ssociated fracture
of any cranial bone. Bilateral black eyes are associated with basal fracture.
Thanks and take care
