Flashes in vision are caused by pressure on the retina, the bundle of nerves in the back of the eye where images are detected and transmitted to the brain. Patients complain of flashing lights or lightning streaks.
Floaters are often seen when fibers move within the vitreous humor, the gelatinous substance made of water and protein fibers that fills the eye. Patients complain of small specks or dots that can be seen against clear backgrounds. Serious vision loss can occur if the retina or vitreous detach from the eye wall.
We can treat many floaters with laser. This is done as an outpatient procedure. Yag laser is used to vaporize the floater and makes it smaller or disappear.
After a YAG Vitreolysis treatment, the patient should notice a difference within a few days. If not, surgical options can be discussed at that time.
