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).
The most common cause of retinal detachment is tiny breaks developing inside the retina. The breaks allow the fluid found between the retina and the lens of the eye to leak underneath the retina. A build-up of fluid can cause the retina to pull away from the blood vessels that supply it with blood.
