What is the area around the optic nerve called in OCT imaging?

• A. Papillomacular axis
• B. Peripapillary
• C. Macular zone
• D. Optic rim

Answer: (B)

Peripapillary describes the zone around the optic nerve head. In OCT, this region is analyzed because the retinal nerve fiber layer wraps around the disc, and its thickness here is a key indicator of glaucomatous damage. The other terms refer to different structures: the papillomacular axis is a line from the fovea to the disc, the macular zone is the central retina in the macula, and the optic rim is the tissue at the edge of the optic nerve head itself. So the area surrounding the optic nerve in OCT imaging is called the peripapillary region.
