What is posterior vitreous separation / detachment?
Posterior vitreous separation, (also known as posterior vitreous detachment) is a common age-related degeneration where the vitreous - the jelly in the back of the eye - becomes detached from the retina. This gives rise to the visualisations of 'floaters'. As the vitreous detaches it pulls on the retina causing the individual to experience flashing lights.
It's not to be confused with the more serious condition, retinal detachment.
There are several warning signs for retinal detachment, and you should get an urgent re-examination if you experience any of the following:
- A sudden increase in the number of floaters in your vision
- A decrease in your visual field
- A veil coming across your vision
