Bleph Risk with Acute Posterior Vitreous Detachment? Recently the vitreous of my eye has pulled away from my retina (normal aging). But it hasn't completely detached resulting in flashes of light at night. Is it advised to have a laser blepharoplasty during this time or should I wait until the vitreous has completely detached. I know retina detachment is a risk with a bleph. Would I be at more risk with the vitreous pulling on the retina (which alone could rarely lead to a retinal detach). What can cause retinal detach during surgery?
