The acronym ILM stands for which anatomical structure?

Explanation:
The structure that ILM refers to is the innermost boundary of the retina, formed by the endfeet of Müller glial cells and serving as the basement membrane between the retina and the vitreous. The precise anatomical term is internal limiting membrane, which is what ILM stands for; many texts and clinicians also use the wording inner limiting membrane, so you’ll see both. On imaging like OCT, it appears as a thin, bright line at the inner surface of the retina and is a key plane involved in vitreoretinal interfaces and related procedures.
