Retinal detachment occurs between
a) Layers of neurosensory retina
b) Neurosensory retina and pigment epithelium
c) Pigment epithelium and choroid
d) None of the above
Correct Answer - B
Ans. is ‘b’ i.e., Neurosensory retina and pigment epithelium
Retina has total ten layers from with out inward :- (i) Pigmented
epithelium, (ii) Layers ofRods & cones, (iii) External limiting
membrane, (iv) Outer nuclear layer, (v) Outer plexiform layers, (vi)
Inner nuclear layer, (vii) Inner plexiform layer, (viii) Ganglionic cell
layer, (ix) Nerve fibre layer, (x) Internal limiting membrane
Broadly these layers are subdivided into two layers based on the
function :?
Neurosensory layer or sensory layer (containing layers ii to x of
above 10 layers) :- for vision.
Pigmented epithelium (layer i) :- Provide metabolic support to
neurosensory layer and acts as an antireflective layer.
So, inner layers are included in neurosensory layer and outer most
layer is retinal pigmented epithelium(RPE).
Retinal detachment is a disorder of eye in which retina peels away
from its underlying layer of support tissue. Usually
there is separation between the neuroepithelium (neurosensory
epithelium or sensory epithelium) and the pigmented
layer, because there is a potential space between these two layers
where fluid can accumulates and can cause separation
