There is no pain associated with retinal detachment, but there are usually symptoms before the retina becomes detached. Primary symptoms include: 1  blurred vision. 2  partial vision loss (as if a curtain has been pulled across your field of vision).
When the retina detaches, it is lifted or pulled from its normal position. If not promptly treated, retinal detachment can cause permanent vision loss. In some cases there may be small areas of the retina that are torn. These areas, called retinal tears or retinal breaks, can lead to retinal detachment.
