What is the area between the macula and the optic nerve head called?

• A. Papillomacular axis
• B. Peripapillary region
• C. Foveal slope
• D. Macular halo

Answer: (A)

The area between the macula and the optic nerve head is the papillomacular axis. This term describes the path of the papillomacular bundle of nerve fibers that run from the macula to the optic nerve head, forming the connection that carries high-detail central vision. Imaging and assessments along this axis focus on the fibers essential for sharp central vision, so it’s a commonly referenced orientation in OCT scans and retinal studies. The other terms point to different concepts: the peripapillary region surrounds the optic nerve head but isn’t specifically the pathway from macula to disc; the foveal slope describes the contour of the fovea rather than a region between macula and disc; and macular halo isn’t a standard anatomical term in this context.
