Retina Conditions
Floaters
Floaters are small dark shapes that float across your vision. They can look like spots, threads, squiggly lines, or even little cobwebs. Most people have floaters that don’t need treatment. But sometimes floaters can be a sign of a more serious eye condition. So if you notice new floaters that appear suddenly and don’t go away, speak to your eye doctor.

Eye Anatomy
Retina: the light-sensitive membrane in the back of the eye that converts light to electrical impulses that are sent to the brain through the optic nerve
Vitreous: also called vitreous humor, a thick, colorless gel that fills the large space in the middle of the eye, behind the lens Macula: the central retina that contains the fovea Fovea: a shallow pit in the center of the retina responsible for our sharpest straight ahead vision Optic nerve: carries the message of vision from the retina to the brain Cornea: transparent convex membrane that covers the pupil and iris of the eye Iris: colored part of the eye that consists of a muscular diaphragm surrounding the pupil and regulates the light entering the eye by expanding and contracting the pupil Pupil: dark circular opening at the center of the iris in the eye, where light enters the eye Lens: focuses light to produce an image on the light-sensitive cells of the retina. Nearly spherical and convex on both sides, it sits behind the pupil |
