    Cavernous sinus thrombosis rarely causes vision loss. This case documents sudden blindness due to ischemic optic neuropathy, even with clear retinal vessels, highlighting a rare complication.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Vascular Medicine

    Background:

    • Cavernous sinus thrombosis (CST) is a rare but serious condition, typically presenting with neurological deficits.
    • Visual disturbances are uncommon in CST, with most cases not involving direct optic nerve compromise.

    Observation:

    • A patient with acute cavernous sinus thrombosis developed markedly elevated intraocular and intraorbital pressures.
    • Despite maintaining patent retinal vasculature, rapid, unilateral blindness ensued within 48 hours.

    Findings:

    • This case represents the first documented instance of blindness caused by ischemic optic neuropathy secondary to cavernous sinus thrombosis.
    • The rapid onset of visual loss suggests an acute ischemic event affecting the optic nerve.

    Implications:

    • This case expands the known spectrum of visual complications associated with cavernous sinus thrombosis.
    • Clinicians should consider ischemic optic neuropathy in the differential diagnosis of sudden vision loss in patients with CST.
    • Prompt recognition and management of CST may be crucial in preventing irreversible visual impairment.
