Posterior Vitreous Detachment

Posterior Vitreous Detachment Common Cause of Floaters Randall V. Wong, M.D. www.TotalRetina.com www.RetinaEyeDoctor.com

What is the Vitreous?
The vitreous is the gel that fills most of the eye.
It contains about 94% water, but, like a jellyfish, has substance.
With time (aging), areas within the vitreous degenerate and become water.

A Posterior Vitreous Detachment Can Cause a Retinal Tear
The vitreous separates from the surface of the retina
Floaters can develop
Is there a tear in the retina?

Posterior Vitreous Detachment Look for A Retinal Tear
Examine within 48-72 hours of onset of symptoms of floaters
The chance of a retinal tear forming is highest within the first 6 weeks of symptoms
Re-examine 6 weeks after the initial onset of symptoms. Tears may be asymptomatic

A Retinal Tear and Retinal Detachment
A retinal tear can cause a retinal detachment

A Retinal Tear No Retinal Detachment
A retinal tear, without associated retinal detachment, may be treated with laser to prevent a retinal detachment from developing
