<prompt> In retinal detachmentEffusion of fluid into the suprachoroidal spaceRetinoschisisSeparation of sensory retina from pigment epitheliumNone of the above  <response>: In retinal detachment the fluid accumulate in subretinal space i.e., the space between neurosensory epithelium sensory epithelium or neuroepithelium and pigmented epithelium.Retinoschisis Vs Retinal detachmentIt has already been explained that in retinal detachment there is separation between neurosensory layer and pigmented epithelium. The separation is between pigmented epithelium and layer of rods cones of neuroepithelium.In Retinoschisis, there is separation within the neurosensory layer, i.e., neurosensory layer or sensory layer of retina splits into two layers at the level of the inner nuclear and outer plexifonn layer. Senile degenerative retinoschisis is a predisposing factor for primary rheugmatogenous retinal detachment.
