Where is the retinal pigment epithelium located relative to the neurosensory retina?

• A. Within the vitreous body
• B. Just outside the neurosensory retina
• C. In the sclera
• D. Within the choroid

Answer: (B)

The retinal pigment epithelium sits right beneath the neurosensory retina, forming a pigmented layer that lies between the neural retina and the choroid. This means it is just outside the neurosensory retina, serving as its outermost layer. It is not located in the vitreous body, nor in the sclera, nor within the choroid itself. This placement helps support photoreceptors and participate in the eye’s metabolic processes.
