Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment ( PVD ).
12.
The risk of retinal tears and detachment associated with vitreous detachment is higher in patients with myopic retinal degeneration, lattice degeneration, and a familial or personal history of previous retinal tears / detachment.
13.
The most effective means of prevention and risk reduction is through education of the initial signs, and encouragement for people to seek ophthalmic medical attention if they have symptoms suggestive of a posterior vitreous detachment.
14.
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 floaters ( in the case of retinal detachment ).
15.
If these liquid pockets are close enough to the interface between the vitreous gel and the retina, they can cause complete separation of the vitreous from the retina in a normally occurring process in older humans called posterior vitreous detachment ( PVD ).
