    Area of Science:

    • Veterinary Neurology
    • Ophthalmology
    • Toxicology

    Background:

    • Sudden blindness in young horses can have various causes.
    • Optic pathway lesions can lead to irreversible vision loss.

    Observation:

    • A 10-month-old thoroughbred colt presented with acute, complete blindness.
    • No other neurological deficits were observed in the colt.

    Findings:

    • Necropsy revealed extensive axonal and myelin degeneration with gliosis in both optic pathways.
    • The specific etiology of the optic nerve damage was undetermined.

    Implications:

    • This case highlights the potential for toxic neuropathy to cause severe optic nerve damage in horses.
    • Further investigation into potential environmental or ingested toxins is warranted for diagnosing and preventing such cases.
