• The eye condition is not serious, common as people age, did not require treatment and is known as a posterior vitreous detachment.
• The vitreous gel undergoes liquefaction ( posterior vitreous detachment or PVD ) and its opacities  visible as floaters  gradually increase in number.
• Floaters are generally harmless, but the sudden onset of recurring floaters may signify a posterior vitreous detachment ( PVD ) or other diseases of the eye.
• 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 ).
• 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.
• 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 ).
