In shaken baby syndrome, an infant is shaken violently by an adult and can be severely injured. ![]() Shaken baby syndrome and abusive head trauma, in particular, can cause a retinal hemorrhage. When an infant or young child has a retinal hemorrhage, it can, unfortunately, be due to child abuse. SEE RELATED: Pseudoxanthoma elasticum (PXE) Child abuse and shaken baby syndrome Other types of hemorrhages – Other kinds of hemorrhages can be associated with diabetes, hypertension, leukemia, radiation treatments and other illnesses. It can indicate underlying disease such as diabetes, leukemia hypertension and endocarditis. It has a distinct appearance with a white spot in the center. Roth spots – A Roth spot is a type of hemorrhage that occurs in the retina. Conditions such as diabetes, rare disorders of the eye or veins, or sickle cell disease can cause this type. ![]() Researchers believe that flame-shaped hemorrhages are linked to artery-based diseases such as hypertension, blood disorders and certain anemias.ĭot or blot hemorrhages – These hemorrhages are found in the deeper layers of the retina and form round, uniform hemorrhages. Sometimes, there is no known cause.įlame-shaped hemorrhage – Retinal flame hemorrhages will show up on an eye exam as thin shapes, like feathers, flames or splinters. Causes can include high blood pressure, trauma or excessive blood vessel growth in the retina due to diseases like diabetes. Your eye doctor will see this on an exam. Vitreous and preretinal hemorrhages – Blood diffuses through the vitreous membrane of the eye and may collect toward the bottom of the eye as it settles. Here are the main types of retinal hemorrhages: The shape, location and severity of a retinal hemorrhage can offer clues to what type it is and the possible origin and cause.

It contains millions of light-sensitive cells called rods and cones and a dense network of small blood vessels. The retina is the sensory membrane that lines the inner back surface of the eyeball. Retinal hemorrhage can be caused by diabetes, high blood pressure, head injuries and even sudden changes in air pressure. ![]() A hemorrhage, or bleeding, happens when these tiny blood vessels are damaged by injury or disease.
