What is the abbreviation for the internal limiting membrane?

• A. ILA
• B. ILM
• C. ILN
• D. ILS

Answer: (B)

ILM stands for the internal limiting membrane. This thin boundary sits at the innermost surface of the retina and is formed by the endfeet of Müller glial cells, separating the retina from the vitreous. In OCT, it appears as a bright, continuous line at the retina’s inner surface and serves as a crucial landmark during vitreoretinal procedures, such as peeling in macular hole or edema treatment. The other letter sequences (ILA, ILN, ILS) are not standard abbreviations for this structure and do not refer to the internal limiting membrane.
