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 is a tear or dislocation of the eyeâs back layer of light-sensitive cells and nerve endings. This can be caused by a severe blow, but it is more commonly the result of a shrinking of the vitreous inside the eyeball, which may occur with aging. Severe shortsightedness is a risk factor, as is diabetes.
