    Summary
    This summary is machine-generated.

    Sudden visual loss, known as ischaemic optic neuropathy, often occurs in older adults. This review of 22 cases highlights hypertension as a key factor, alongside other potential causes like migraine and trauma.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Vascular Medicine

    Background:

    • Ischaemic optic neuropathy (ION) is a significant cause of sudden, painless vision loss in middle-aged and elderly individuals.
    • Characterized by optic disc swelling and visual field defects, ION impacts the optic nerve's blood supply.

    Observation:

    • This study reviewed 22 cases of ischaemic optic neuropathy.
    • The review examined the diverse etiological factors contributing to ION.

    Findings:

    • Hypertension is identified as the predominant cause in non-arteritic ION cases.
    • Cranial arteritis, vascular disease, migraine, and trauma are also recognized as potential contributors to ION.

    Implications:

    • Understanding these risk factors is crucial for diagnosing and managing ION.
  • Further research into the specific mechanisms of ION related to hypertension, migraine, and trauma is warranted.
