The vitreous is a jelly like substance that fills the eye and forms its shape. It is located behind the lens and is attached to the retina by the posterior vitreous membrane. As we get older, the vitreous may liquify. As this happens, the posterior vitreous may tug on the retina. As a result, small clumps or particles may appear in the vitreous. These particles are often suspended in this jelly like fluid and don’t float downward. As light passes through the pupil to the retina, some floaters may be right in the path of light and will form a shadow on the back of the retina. This will appear as a spot moving around in your field of vision.
Sometimes when the vitreous tugs on the retina, it may cause you to see a flash of light. In rare incidences, this tugging may result in a tear in the retina. A retinal tear is a serious condition and needs immediate medical attention. Flashes and floaters can be an annoyance, but can also indicate a retinal detachment. If you notice a sudden increase in floaters with our without flashes, please see your eye care professional immediately.
