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).
A detached retina occurs when the retina is pulled away from its normal position in the back of the eye. The retina sends visual images to the brain through the optic nerve. When detachment occurs, vision is blurred.A detached retina is a serious problem that can cause blindness unless it is treated.sually the vitreous separates from the retina without causing a problem. But sometimes the vitreous pulls hard enough to tear the retina in one or more places, causing the retinal detachment. Fluid may pass through the retinal tear and lift the retina off the back of the eye like wallpaper can peel off a wall.
