    Area of Science:

    • Ophthalmology
    • Neurology

    Background:

    • Anterior ischemic optic neuropathy (AION) is a significant cause of vision impairment in individuals over middle age.
    • AION is frequently misdiagnosed as an intracranial tumor due to overlapping symptoms.
    • Understanding AION is crucial for accurate diagnosis and management in elderly patients.

    Purpose of the Study:

    • To review the clinical characteristics of anterior ischemic optic neuropathy.
    • To discuss the underlying pathogenesis of AION.
    • To outline current treatment strategies for AION.

    Main Methods:

    • Literature review of clinical features, pathogenesis, and treatment of AION.
    • Analysis of diagnostic challenges, particularly differentiating AION from intracranial masses.
    • Synthesis of current therapeutic approaches.

    Main Results:

    • AION presents with characteristic visual field defects and optic disc edema.
    • Pathogenesis involves impaired blood supply to the optic nerve head.
    • Differential diagnosis from intracranial tumors is a common clinical challenge.

    Conclusions:

    • AION is an underrecognized yet common cause of vision loss in the elderly.
    • Timely diagnosis and appropriate management can mitigate vision impairment.
    • Further research into AION pathogenesis may improve treatment outcomes.
