Vitreous Haemorrhage and Vitreous Opacity (Floaters)

Procedure information

  • Surgery is usually performed under local anaesthesia with sedation. It is usually performed as a day operation.
  • Depending on the cause of the vitreous haemorrhage, surgery usually involves vitrectomy and possibly a combination of laser or gas injection.
  • Vitrectomy involves the usage of micro-instruments through the white part of the eye (sclera) to remove the vitreous gel.

Vitreous Haemorrhage

  • Vitreous haemorrhage is bleeding into the vitreous cavity of the eye.
  • The blood in the vitreous cavity scatters light and obscures light from being focused onto the retina.
  • Symptoms can include floaters, shadows, blurry vision and loss of vision.
  • There are many causes of vitreous haemorrhage. The most common causes include:
    • Posterior vitreous detachment with or without a retinal tear
    • Diabetic retinopathy
    • Retinal vein occlusions – Trauma
  • The management of vitreous haemorrhage involves accurately identifying and treating the underlying cause, and in some cases surgical removal of the blood via a vitrectomy operation.

Vitreous Opacity (Floaters)

  • New onset of floaters may be a sign of a retinal tear or detachment and should be assessed urgently to avoid further loss of vision. Please make an appointment with Dr. Sia to have this looked at.
  • Long-standing floaters is usually caused by ageing of the vitreous gel. It may also be caused by previous vitreous haemorrhage, inflammation or trauma.
  • Long-standing floaters are usually benign and does not require treatment. However, some patients may experience troubling symptoms due to these floaters.
  • In these circumstances, floaters can be removed surgically with a vitrectomy operation.
  • Please make an appointment to see Dr. Sia for further discussion about your floaters.
