    Optic nerve drusen may increase the risk of developing ischemic optic neuropathy, even in young adults. This suggests a potential causal link rather than a coincidental occurrence.

    Area of Science:

    • Ophthalmology
    • Neurology

    Background:

    • Optic nerve drusen are abnormal deposits within the optic nerve head.
    • Idiopathic ischemic optic neuropathy (ION) typically affects older individuals.

    Observation:

    • Five eyes across four patients with optic nerve drusen developed ischemic optic neuropathy.
    • Two affected patients were in their 20s, an age group where ION is uncommon.

    Findings:

    • The concurrence of optic nerve drusen and ION, especially in young patients, suggests a link beyond chance.
    • Mechanical distortion of optic nerve vasculature by drusen may cause infarction.

    Implications:

    • Optic nerve drusen may be a risk factor for ischemic optic neuropathy.
    • This finding could impact the diagnostic and management strategies for patients with optic nerve drusen.
