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).
What causes a retinal detachment? Breaks in the retinal tissue (retinal holes and retinal tears) are normally found in approximately 10% of people. In a small minority of persons with retinal breaks, liquid vitreous leaks beneath the retina, separating it from the eyewall and causing a retinal detachment. A sudden separation of the vitreous from the retina (posterior vitreous detachment) is often the inciting event causing a retinal break or detachment.
