Intraocular hemorrhage may be caused by physical trauma (direct injury to the eye); ocular surgery (such as to repair cataracts); or other diseases, injuries, or disorders (such as diabetes, hypertension, or shaken baby syndrome). [2] Severe bleeding may cause high pressure inside the eye, leading to blindness.
[2] [3] Generally only one eye is affected. [2] Causes can include coughing, vomiting, heavy lifting, straining during acute constipation or the act of "bearing down" during childbirth, as these activities can increase the blood pressure in the vascular systems supplying the conjunctiva. Other causes include blunt or penetrating trauma to the eye.
Some injuries can cause blood vessels in the back of the eye to bleed. Trauma is the leading cause of vitreous hemorrhage in young people, and accounts for 12–18.8% of cases in adults. [ 1 ]
Experiencing trauma can sometimes lead to post-traumatic stress disorder (PTSD). This serious mental health condition is marked by changes in mood, intrusive memories, avoidant behavior, and a ...
A microhyphema, where red blood cells are hanging in the anterior chamber of the eye, is less severe. A layered hyphema when fresh blood is seen lower in the anterior chamber is moderately severe. A full hyphema (total hyphema), when blood fills up the chamber completely, is the most severe. [1]
A red eye is an eye that appears red due to illness or injury. It is usually injection and prominence of the superficial blood vessels of the conjunctiva , which may be caused by disorders of these or adjacent structures.
Eye examination may be done to check the eye(s) conditions, for instance to check how well the patient sees straight ahead, off to the sides and at different distances. Blood tests may provide information about the patient's overall health and may also reveal the medical condition that may have caused retinal hemorrhage.
In contrast to Post-Traumatic Stress Disorder, which springs from fear, moral injury is a violation of what each of us considers right or wrong. The diagnosis of PTSD has been defined and officially endorsed since 1980 by the mental health community, and those suffering from it have earned broad public sympathy and understanding.
