Does doing a laser retinopexy around areas of lattice degeneration reduce the risk of tractional tears ensuing from posterior vitreous detachment?

Yes,it should reduce. Yes, the decision for retinopexy is best made by retina subspecialist who can assess whether the degree of lattice ; or the presence of high risk thinning would warrant the risks. Retinopexy creates a tighter bonding so that in event of PVD there is lower likelihood of retinal tears.
