While surgeries do exist to correct for severe cases of<unk> s, there are no medications (including eye drops) that can correct for this vitreous deterioration.<unk> s are often caused by the normal aging process and will usually become less bothersome as a person learns to ignore them. Looking up/down and left/right will cause the<unk> s to leave the direct field of vision as the vitreous humour swirls around due to the sudden movement. If<unk> s significantly increase in numbers and/or severely affect vision, then one of the below treatments may be necessary. , insufficient evidence is available to compare the safety and efficacy of surgical vitrectomy with laser vitreolysis for the treatment of<unk> s. A 2017 Cochrane Review did not find any relevant studies that compared the two treatments. Aggressive marketing campaigns have promoted the use of laser vitreolysis for the treatment of<unk> s. No strong evidence currently exists for the treatment of<unk> s with laser vitreolysis. The strongest available evidence comparing these two treatment modalities are retrospective case series. Surgery 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. Like most invasive surgical procedures, however, vitrectomy carries a risk of complications, including: retinal detachment, anterior vitreous detachment and macular edema – which can threaten vision or worsen existing<unk> s (in the case of retinal detachment). Laser Laser vitreolysis is a possible treatment option for the removal of vitreous strands and opacities<unk> s). In this procedure an ophthalmic laser (usually a yttrium aluminium garnet (YAG) laser) applies a series of nanosecond pulses of low-energy laser light to evaporate the vitreous opacities and to sever the vitreous strands. When performed with a YAG laser designed specifically for vitreolysis, reported side effects and complications associated with vitreolysis are rare. However, YAG lasers have traditionally been designed for use in the anterior portion of the eye, i.e. posterior capsulotomy and iridotomy treatments. As a result, they often provide a limited view of the vitreous, which can make it difficult to identify the targeted<unk> s and membranes. They also carry a high risk of damage to surrounding ocular tissue. Accordingly, vitreolysis is not widely practised, being 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. However, the MedicineNet web site states that "there is no evidence that this laser treatment is effective. The use of a laser also poses significant risks to the vision in what is otherwise a healthy eye." Medication Enzymatic vitreolysis has been trialed to treat vitreomacular adhesion (VMA) and anomalous posterior vitreous detachment. Although the mechanism of action may have an effect on clinically significant<unk> s, there are no clinical trials being undertaken to determine whether this may be a therapeutic alternative to either conservative management, or vitrectomy. Atropine Dropping low doses of atropine onto the eye dilates the pupil, thus reducing shadow formation on the retina by<unk> s.
