<prompt> Retinal detachment is -Separation of sensory epithelium from pi gmented epitheliumSeparation of pigmented epithelium from choroidSeparation of nuclear layer from plexiform layerNone  <response>: Ans. is a i.e.. Separation of sensory epithelium from pigmented epithelium Ref: Khurana 4th e p. 276o Retina has total ten layers from with out inward i Pigmented epithelium, ii Layers of Rods 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 membraneo Broadly these layers are subdivided into two layers based on the functionNeurosensorv layer or sensory layer containing layers ii to x of above 10 layers for vision.Pigmented epithelium layer iProvide metabolic support to neurosensorv layer and acts as an antireflective layer.o So, inner layers are included in neurosensorv layer and outer most layer is retinal pigmented epithelium RPEo Retinal detachment is a disorder of eye in which retina peels away from its underlying layer of support tissue,o 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.
