Flashes & Floaters
Inside the eye is jelly-like substance called the vitreous humour.
Within the vitreous, debris can be ﬂoating around which can cast shadows on the retina, the back surface of the eye. This debris is called ﬂoaters which are generally small and can be noticed against plain pale backgrounds like white paper, white walls and blue clear sky. They can move randomly especially when you move your eye around.
Most ﬂoaters are natural and safe. Occasionally they can indicate that the vitreous is separating from the retina, which is called a Vitreous Detachment. Sometimes, this can be a sign that a tear or hole in the retina has developed. These changes are normally painless, and can be associated with ﬂashing lights in your vision.
These symptoms are more common with patients who are short sighted (myopic) or in certain environments for example playing contact sports like rugby and boxing. If you experience these symptoms, we advise you to seek medical advice swiftly.
