A vitreous hemorrhage is usually caused by leakage of damaged or abnormal blood vessels in the back of the eye. The blood cells that leak into the vitreous humor reflect light that is entering the eye and distort vision.
Medical conditions and injuries that can cause damage to the blood vessels of the eye and vitreous hemorrhage include:
Rarely, tumors or bleeding from another part of the body
Blood in the gel of the eye scatters the light which may cause:
Black spots, floaters, or light flashes
Blurriness or haziness
Seeing red hues
Scotomas—changes in or distortion of visual field (blind spot)
For some, vision problems are worse in the morning.
You will be asked about your symptoms and medical history. A physical exam will be done. A hemorrhage may be suspected based on symptoms and risk factors.
A vitreous hemorrhage can usually be detected with a special tool called a slit-lamp. The lamp allows the doctor to look at the back of the eye to look for blood vessel leakage or damage. If a slit-lamp is not available, bleeding may be detected with ultrasound.
The vitreous blood usually resolves on its own without treatment. During this time, symptoms will be monitored for any changes.
Treatment of the cause may be necessary. For example, a change in glucose management may help with diabetic retinopathy or surgery may be needed for a retinal detachment.
Medications may be needed to relieve some of the bleeding. Options include:
Eye drops to reduce eye pressure, and/or dilate the pupils
Vascular endothelial growth factor inhibitors to prevent abnormal new blood vessels from forming
A severe hemorrhage or bleeding that doesn’t stop on its own may need to be treated with surgery. Surgical options include:
Laser panretinal photocoagulation—Lasers are used to heat blood vessels to slow or stop abnormal new blood vessels from forming.
—Retinal detachment or persistent vitreous hemorrhage may be treated by removal of the gel-like substance from the eye and replacement with gas or solution. Over time the eye will form new gel-like substance for the eye.
To help reduce your chance of a vitreous hemorrhage:
Manage chronic conditions like diabetes according to your treatment plan.
Take safety measures to avoid injury, such as wearing protective eye wear or a seatbelt.
Get regular eye exams as advised by your eye doctor.
Seek prompt treatment for any eye problems or injuries.
