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).
Causes of Retinal Detachment. Retinal detachment is the result of vitreous liquid (the fluid inside the eye) leaking through a small hole or tear in the retina. When this occurs, the retina slowly peels away from the adjacent tissue, damaging the blood supply to the retina and preventing it from working properly.etinal detachment occurs when the retina separates from the tissue and blood vessels located in the back of the eye. Often brought on by a retinal tear, retinal detachment may lead to permanent vision loss or complete blindness if left untreated.
