Can anterior vitreous detachment occur before pvd? does it reduce the retinal risks assoc with cataract surgery? symptoms other than floaters?

Same risk of RD: The anterior hyaloid face is juxtaposed to the posterior capsule of the lens. The vitreous base is adjacent to the ora serrata. Any anterior segment trauma, including complicated cataract surgery, can cause either of these regions of the vitreous to involute before the posterior vitreous. Changes in the vitreous composition account for the high rate of pvd. Retinal tears cause the rd.

Vitreous detachment: May occur at the level of the anterior retina adjacent to an area called the ora serrata. The vitreous may delaminate from the retina at any location, meaning either posterior or anterior at anytime either from trauma or idiopathic. If the vitreous is already detached from the retina, then the risks of a retinal detachment is theoretically reduced.
