Benign eye floaters don't usually require medical treatment or intervention; if eye floaters are bothersome, moving the eyes can shift them out of the field of vision. Eye disease and injury and diabetic retinopathy sometimes cause eye floaters, although WebMD notes that serious eye disorders are sometimes also associated with floaters, including eye tumors and vitreous hemorrhage, among others. When eye floaters affect vision, a surgical procedure may be necessary to remove the floating debris causing the eye floaters, replacing it with a solution of salt.
Usually, moving the eyes up and down shifts the fluid in the eyes and helps to move floaters out of the field of vision. Looking side to side is not as helpful as an up-and-down motion, according to WebMD.
A surgical procedure known as a vitrectomy may become necessary if the vision is affected by eye floaters that are numerous and dense. This procedure is used to surgically remove the vitreous itself via multiple incisions in the eye. Although advances in instrumentation for use in the procedure has reduced the number of complications associated with it, the risks are still quite substantial. Complications of vitrectomy include retinal tears, detachment and the development of cataracts. For the high risk posed by these complications, most surgeons do not recommend the procedure unless a patient's vision is seriously affected.
