Area of Science:

  • Neuroscience
  • Radiology
  • Ophthalmology

Background:

  • The visual pathway, from globes to occipital cortex, is susceptible to diverse pathologies.
  • Optic nerve diseases can mimic intracranial conditions due to its brain tract nature.

Purpose of the Study:

  • To review the normal anatomy of the visual pathway.
  • To present computed tomography (CT) and magnetic resonance (MR) imaging techniques for visual pathway evaluation.
  • To discuss pathologic processes affecting the optic nerve and visual pathways.

Main Methods:

  • Review of normal optic nerve and visual pathway anatomy.
  • Description of CT and MR imaging protocols for visual pathway assessment.
  • Discussion of intrinsic and extrinsic pathologic conditions.

Main Results:

  • Clinician's physical examination and visual function tests aid in localizing lesions.
  • Imaging techniques like CT and MR are crucial for detailed evaluation.
  • Understanding anatomy and pathology optimizes diagnostic imaging.

Conclusions:

  • Accurate localization of visual dysfunction is key for targeted imaging.
  • Comprehensive knowledge of visual pathway anatomy and pathology aids radiologists.
  • CT and MR imaging are essential tools for diagnosing visual pathway disorders.
