Pathological optic-disc cupping can stem from various conditions beyond glaucoma. Accurate diagnosis requires careful patient history, funduscopic examination, and advanced imaging to differentiate causes and avoid misdiagnosis.

Area of Science:

  • Neuro-ophthalmology
  • Optic Nerve Disorders

Background:

  • Pathological optic-disc cupping is commonly associated with glaucoma.
  • However, numerous less-common neuro-ophthalmic conditions can also cause optic-disc excavation.
  • Misinterpretation of optic-disc cupping can lead to misdiagnosis in up to 20% of patients.

Purpose of the Study:

  • To review entities causing optic-disc cupping.
  • To differentiate these conditions based on characteristics and pathophysiology.
  • To outline diagnostic strategies for optic-disc cupping.

Main Methods:

  • Review of neuro-ophthalmic literature on optic-disc cupping.
  • Analysis of differentiating characteristics and pathophysiologies.
  • Discussion of diagnostic approaches, including imaging and clinical assessment.

Main Results:

  • Multiple conditions, unrelated to elevated intraocular pressure, can cause optic-disc excavation.
  • Accurate diagnosis remains challenging despite advanced imaging.
  • Optical coherence tomography and careful clinical evaluation aid in diagnosis.

Conclusions:

  • Optic-disc cupping results from diverse disorders, necessitating a thorough understanding of optic nerve anatomy and vasculature.
  • Neurological conditions, including treatable tumors, can present with optic-disc cupping.
  • Distinguishing glaucomatous from non-glaucomatous optic-disc cupping relies on patient history, visual fields, and funduscopic findings.
