Floaters in the eyes are a common occurance. You have a thick gel material in the middle of your eyes. Over time it liquifies and can sometimes clump together. When you look in the light, you see the shadows of these things and see them as floaters. Floaters are generally not a problem, though they can be annoying.
New floaters can be an indication of a retinal problem, such as a hole or tear. The first picture shows an uneventful vitreous
detachment where the thick gel pulls away from the wall of the eye. The second figure shows how the movement of the vitreous can pull on the retina can cause a retinal tear. Retinal tears can progress to a retinal detachment
. If left untreated, you can lose vision. If caught early, laser can be used to strengthen the retina. If the retina is already detached, then surgery may be necessary to reattach the retina.
Warning signs of a retinal detachment are a sudden increase in floaters, flashes of light
(like a lightening storm, arc
of light), or a shadow/veil in the periphery of your vision.
