Which visual field finding may be present in papilledema?

• A. Central scotoma
• B. Enlarged blind spot
• C. Superior altitudinal defect
• D. Bitemporal hemianopia

Answer: (B)

Papilledema involves swelling of the optic disc from raised intracranial pressure. This edema pushes outward at the optic nerve head, enlarging the area where the retina lacks بن normal sensitivity—the physiologic blind spot. On visual field testing, that swelling makes the blind spot appear bigger because more adjacent fibers are affected, broadening the defect around the disc. Central scotoma points to macular or optic nerve issues that specifically involve central vision, not typically the disc edema pattern seen with papilledema. An altitudinal defect, especially superior, is more characteristic of ischemic optic neuropathy or other vascular/nerve fiber layer issues. Bitemporal hemianopia arises from a lesion at the optic chiasm, such as a pituitary tumor, and is not a typical feature of papilledema.
