Vitreous Hemorrhage

Vitreous hemorrhage is bleeding into the vitreous cavity, from proliferative diabetic retinopathy, retinal vein occlusion, trauma, or posterior vitreous detachment tearing a vessel. Clinical: sudden floaters/curtain and reduced red reflex. Treatment: head elevation and observation; treat underlying cause (scatter laser for ischemic retina); pars-plana vitrectomy if it does not clear in 1-3 months or if retinal detachment is present.

Common Symptoms

Sudden floaters/curtain; reduced red reflex; by cause (diabetes/trauma/PVD)

Causes and Pathogenesis

Neovascular/vitreous-traction bleeding enters the vitreous cavity, obscuring vision.

Treatment

Observation/head elevation; treat cause (scatter laser); vitrectomy if non-clearing or detachment

Preventive Measures

Treat diabetic retinopathy; scatter laser for ischemia.
