Vitreous opacities

Vitreous opacities, often appearing as floaters, are common, usually harmless, and result from the shrinking and clumping of the vitreous gel, the gel-like substance that fills most of the eye.  

  • What they are:
    Vitreous opacities are visible structures within the vitreous gel, the clear, jelly-like substance that fills the space between the lens and the retina in your eye. 



  • Causes:
    • Age-related changes: As we age, the vitreous gel naturally liquefies and can shrink, forming strands and clumps that cast shadows on the retina, appearing as floaters. 
    • Posterior vitreous detachment (PVD): This is a common age-related process where the vitreous gel detaches from the retina, often associated with floaters.
    • Other conditions: Vitreous opacities can also be associated with inflammation, vitreous hemorrhage, or other eye conditions. 
  • Symptoms:
    • Floaters: The most common symptom is the appearance of small, moving spots, shadows, or other shapes in the visual field. 
    • Flashes: In some cases, floaters may be accompanied by flashes of light. 

  • When to seek medical attention:
    • If you experience a sudden onset of many new floaters or flashes, especially accompanied by a loss of vision or pain, it's important to seek immediate medical attention as these could be signs of a more serious condition like retinal detachment. 
    • While most floaters are harmless, they can be a sign of an underlying eye condition that needs to be evaluated by an eye doctor. 

  • Treatment:
    • In most cases, vitreous opacities are benign and do not require treatment.
    • If floaters become significantly bothersome or interfere with vision, a doctor may recommend options like vitrectomy, a surgical procedure to remove the vitreous gel. 

  • Imaging:
    • OCT (Optical Coherence Tomography) imaging is commonly used to measure the degree of vitreous opacification. 
    • B-scan ultrasound and wide-field color fundus photos are also used to document and assess vitreous opacities.
