Lamellar structure. A schematic of a lamellar structure for a eutectic system. Lamellar structures or microstructures are composed of fine, alternating layers of different materials in the form of lamellae. They are often observed in cases where a phase transformation front moves quickly, leaving behind two solid products, as in rapid cooling of eutectic (such as solder) or eutectoid (such as pearlite) systems.

A break in the front or back wall. of the cyst causes a lamellar hole to form. The term âlamellarâ refers to partial. thickness. A lamellar macular hole (figure. 2) is by definition a partial thickness. macular hole, where the inner layers of. the macula are involved with traction and.
