Treatment
- Vitrectomy may be successful in treating more severe cases; The technique usually involves making three openings through the part of the sclera known as the pars plana. Of these small gauge instruments, one is an infusion port to resupply a saline solution and maintain the pressure of the eye, the second is a fiber optic light source, and the third is a vitrector. The vitrector has a reciprocating cutting tip attached to a suction device. This design reduces traction on the retina via the vitreous material. A variant sutureless, self-sealing technique is sometimes used.
For most cases, vitrectomies for floaters are successful but complications do occur. Complications include cataracts, retinal detachment, macular edema, hypotony, residual floaters, anterior vitreous detachment and optic nerve damage.
- Laser vitreolysis: In this procedure an ophthalmic laser (usually an Yttrium aluminium garnet "YAG" laser) is focused onto the floater and in a series of brief bursts, the laser vaporizes and lyses (cuts) the collagen strands of the floater. It is an outpatient process, which is much less invasive to the eye than a vitrectomy, with potentially fewer side effects. As of July 2010, laser treatment is not widely practiced and is performed by very few specialists. One of them, John Karickhoff, has performed the procedure more than 1,400 times and claims a 90 percent success rate. The MedicineNet web site states that "there is no evidence that this is effective. The use of a laser also poses significant risks to the vision in what is otherwise a healthy eye."

Famous quotes containing the word treatment:
“[17th-century] Puritans were the first modern parents. Like many of us, they looked on their treatment of children as a test of their own self-control. Their goal was not to simply to ensure the child’s duty to the family, but to help him or her make personal, individual commitments. They were the first authors to state that children must obey God rather than parents, in case of a clear conflict.”
—C. John Sommerville (20th century)
“Narcissist: psychoanalytic term for the person who loves himself more than his analyst; considered to be the manifestation of a dire mental disease whose successful treatment depends on the patient learning to love the analyst more and himself less.”
—Thomas Szasz (b. 1920)
“Our treatment of both older people and children reflects the value we place on independence and autonomy. We do our best to make our children independent from birth. We leave them all alone in rooms with the lights out and tell them, “Go to sleep by yourselves.” And the old people we respect most are the ones who will fight for their independence, who would sooner starve to death than ask for help.”
—Margaret Mead (1901–1978)
