Eye Flashes and Floaters
Vitreous contraction floaters are floaters due to shrinking of the jellylike substance that fills the back part of the eyeball, called the vitreous humor, and require no treatment. Many flashes are also due to shrinking of vitreous substance and do not require treatment. Sometimes if a person has many floaters that interfere with vision, doctors may use a hollow needle to remove the vitreous humor from the eye and replace it with salt water. This surgical procedure is called vitrectomy. However, many doctors think vitrectomy should not be done for floaters because the procedure may cause detachment of the retina or cataracts and because sometimes floaters remain afterward. Other disorders causing symptoms are treated. For example, surgery is done to repair a detached retina. Antimicrobial medications are used for infections causing vitreous inflammation.
