What is Vitreous hemorrhage and explain in detail?
Vitreous hemorrhage is the extravasation, or leakage, of blood into the areas in and around the vitreous humor of the eye. The vitreous humor is the clear gel that fills the space between the lens and the retina of the eye. A variety of conditions can result in blood leaking into the vitreous humor, which can cause impaired vision, floaters, and photopsia.

Symptoms
Common symptoms of vitreous hemorrhage include:

Blurred vision
Floaters – faint cobweb-like apparitions floating through the field of vision
Reddish tint to vision
Photopsia – brief flashes of light in the peripheral visionSmall vitreous hemorrhage often manifests itself as "floaters." A moderate case will often result in dark streaks in the vision, while dense vitreous hemorrhage can significantly inhibit vision.

Causes
There are many factors known to cause vitreous hemorrhage.

Diabetic retinopathy
The most common cause found in adults is diabetic retinopathy. Abnormal blood vessels can form in the back of the eye of a person with diabetes. These new blood vessels are weaker and prone to breaking and causing hemorrhage. Diabetic retinopathy accounts for 31.5–54% of all cases of vitreous hemorrhage in adults in the United States.

Trauma
Some injuries can cause blood vessels in the back of the eye to bleed
