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).
Retinal detachment occurs most often as a result of degenerative changes in the peripheral retina and vitreous body, which produce holes or tears in the retina that can range from minute breaks no larger than 0.1 mm to extensive holes that extend over the entire fundus.
