Flashes
and Floaters
The vitreous is a clear, jelly-like substance that fills
the back of the eye in front of the retina. As the eye
ages, the vitreous may detach from the retina (vitreous
detachment) creating shadows on the retina.
The
floaters created appear as dots and squiggles. When
the vitreous pulls or tugs on the retina, one may see
lightning flashes. The pull of the vitreous can sometimes
cause holes in the retina and lead to retinal detachment.
If
you develop flashes or floaters, an eye exam is necessary
to check for a retinal tear or detachment right away.
Retinal
Tear/Detachment
The retina is a delicate structure and is vulnerable
to tearing. Previous eye surgery, trauma, nearsightedness
and family history of retinal detachment can increase
the risk of a retinal tear. When the retina tears, fluid
can leak between the retina and the back, outer wall
of the eyeball, pushing the retina off of the eye.
Laser
treatment and retina surgery are used to preserve vision.
