Anterior vitrectomy entails removing small portions of the vitreous humor from the front structures of the eye—often because these are tangled in an intraocular lens or other structures. Pars plana vitrectomy is a general term for a group of operations accomplished in the deeper part of the eye, all of which involve removing some or all of ...
In symptomatic VMA patients with more significant vision loss, the standard of care is pars plana vitrectomy (PPV), which involves surgically removing the vitreous from the eye, thereby surgically releasing the symptomatic VMA. In other words, vitrectomy induces PVD to release the traction/adhesion on the retina.
Eye infections, including pink eye, may also trigger floaters. "Eye infections can cause floaters if the infection is severe enough to cause white blood cells to be released into the eye to try to ...
Vitrectomy is also used for proliferative vitreoretinopathy, which is the growth of scar tissue on the retina that can occur after a retinal detachment. [8] [23] [24] In this technique, the vitreous gel is removed from the eye to relieve the pulling force on the retina.
What causes a floater in your eye? Eye floaters are a normal part of aging, but some people turn to vitrectomy surgery to get rid of floaters from their vision.
Floaters are, in fact, visible only because they do not remain perfectly fixed within the eye. Although the blood vessels of the eye also obstruct light, they are invisible under normal circumstances because they are fixed in location relative to the retina, and the brain "tunes out" stabilized images through neural adaptation.

Vitreous hemorrhage is diagnosed by identifying symptoms, examining the eye, and performing tests to identify the cause. Some common tests include: Examination of the eye with a microscope; Pupil dilation and examination; An ultrasound examination may be used if the doctor does not have a clear view of the back of the eye
A ring of floaters or hairs just to the temporal side of the central vision As a posterior vitreous detachment proceeds, adherent vitreous membrane may pull on the retina. While there are no pain fibers in the retina, vitreous traction may stimulate the retina, with resultant flashes that can look like a perfect circle.
