Vitreous Hemorrhage

Vitreous hemorrhage occurs when blood leaks into the vitreous — the clear, gel-like substance that fills the center of the eye. This bleeding can block light from reaching the retina, causing sudden vision loss, a shower of floaters, or a reddish tint to vision. Common causes include proliferative diabetic retinopathy, retinal tears, retinal vein occlusion, and trauma. Mild hemorrhages may clear on their own over weeks to months, but severe cases or those caused by an underlying retinal tear or detachment require prompt evaluation and treatment. A vitrectomy may be needed to remove the blood and repair any underlying damage.
