What causes retina detachment?

Flashes floater veil: Vitreous separation ; traction on the retina causes retinal tears-causing vitreous floaters ; hazy vision. Laser helps to prevent the tear from progressing to a retinal detachment as fluid flows though untreated tears and the retina falls off the back of your eye-like wallpaper coming off a wall. This causes a veil in your side vision then central vision loss. It is painless.

Many things...: Trauma, retinal tears, genetic predisposition, prematurity, retinal thinning and lattice formation, any type of intraocular surgery, diabetes and more.

Many possible causes: As we age, the vitreous may pull away from its attachment to the retina at the back of the eye. If the vitreous pulls hard enough to tear the retina in one or more places, fluid may pass through, lifting the retina off the back of the eye, causing it to detach. Some risk factors for detachment are: nearsightedness, trauma to the eye or a family history of retinal detachment.

That's correct above. Most commonly retinal detachments originate with a tear in the retina (rhegmatogenous detachment). However, retinas can detach without a tear. This would include inflammation (serous detachment) and scarring/fibrovascular proliferation (traction detachment, most commonly diabetic
