Vitreous haemorrhage is bleeding into the clear jelly inside the eye called the vitreous.
Why vitreous haemorrhage occurs
Fragile or damaged blood vessels can leak or rupture, releasing blood into the gel. Common causes include diabetic eye disease, retinal tears, and trauma.
- Patients often notice sudden floaters, cobwebs, or dark shapes
- Vision may become hazy, shadowed, or completely blocked in severe cases
- Bleeding itself is usually painless but very alarming
- Risk is higher in people with diabetes or previous retinal problems
Assessment and treatment
Any suspected vitreous haemorrhage needs urgent specialist assessment to rule out retinal detachment. Treatment aims to find and address the bleeding source while monitoring how the blood clears.
- Eye examination and ultrasound help assess the retina when vision is cloudy
- Laser, injections, or surgery may be needed for underlying retinal disease
- Small haemorrhages sometimes clear naturally over weeks or months
- Report new flashes of light or a curtain over vision immediately
