    Relative afferent pupillary defects can indicate early optic nerve damage in patients with ocular hypertension and glaucoma. This sign, often associated with neurological issues, may solely result from glaucomatous damage.

    Area of Science:

    • Ophthalmology
    • Neuro-ophthalmology

    Background:

    • Open-angle glaucoma is a progressive optic neuropathy.
    • Asymmetrical visual field loss is common in glaucoma.
    • Relative afferent pupillary defect (RAPD) is a key clinical sign.

    Observation:

    • Seven patients with asymmetrical open-angle glaucoma were studied.
    • The presence and stage of RAPD were assessed in relation to glaucoma severity.

    Findings:

    • Relative afferent pupillary defects were observed in all seven patients.
    • RAPD can manifest at any stage of glaucoma.
    • The presence of RAPD may signify the earliest optic nerve damage in ocular hypertension.

    Implications:

    • Consider glaucomatous damage as a cause of RAPD, even without other neurological findings.

  • RAPD can be an early indicator of glaucoma progression in ocular hypertensive patients.
  • This finding aids in the early diagnosis and management of glaucoma.
