Flashes and Floaters
Flashes and floaters occur when there are changes in the back part of the eye. Floaters are small dark shapes that can appear in your field of vision. Sometimes they can look like lines, cobwebs, or other shapes and they move. Flashing lightscan be described as small camera flashes or a spark or light that is arc-shaped in the periphery of the vision.
Cause
Floaters occur when the vitreous (jelly in the back of the eye) degenerates and creates densities in the eye that cast a shadow on the retina. The vitreous degeneration
Cause
Floaters occur when the vitreous jelly in the back of the eye degenerates and causes shadows on the retina. These strands are inside your eye. The vitreous tends to degenerate with age. The process is accelerated in people who are near sighted, or those who have ocular trauma. Approximately 10-12% of posterior vitreous detachments are associated with retinal tears or detachment. Flashes occur when the vitreous is tugging on the retina. It is very important to get a dilated examination when you have flashes or floaters.
