The layer comprised of the footplates of Muller cells and their basal lamina is called:

• A. Internal limiting membrane (ILM)
• B. Outer limiting membrane (OLM)
• C. Internal nuclear layer (INL)
• D. Outer nuclear layer (ONL)

Answer: (A)

The boundary between the retina and the vitreous is formed by the endfeet of Müller glial cells together with their basement membrane, creating the internal limiting membrane. This innermost retinal layer lines the vitreous side and serves as the attachment point for the retina to the gel-filled cavity. The other layers mentioned are located differently: the outer limiting membrane sits at the outer retina where photoreceptors meet Müller cells; the inner nuclear layer houses the nuclei of bipolar, horizontal, amacrine, and Müller cells; the outer nuclear layer contains photoreceptor cell bodies.
