</html><description>In eye care, **cup** most often refers to the central depression within the optic nerve head (the optic disc) seen during an eye exam. It is a normal anatomical feature, but its size and shape can change in certain diseases. Clinicians describe cup appearance to help assess the health of the optic nerve, especially in glaucoma care. The term also appears in clinical documentation, imaging reports, and teaching about optic nerve anatomy.</description></oembed>
