A rare case of cavernous sinus thrombosis (CST) led to permanent bilateral blindness due to retinal artery occlusion and optic neuropathy. This highlights a critical, previously undocumented complication of CST.

Area of Science:

  • Ophthalmology
  • Neurology
  • Infectious Diseases

Background:

  • Cavernous sinus thrombosis (CST) is a rare but serious condition, often originating from infections in the head and neck region.
  • Reconstructive surgery for head and neck tumors can present unique challenges for infection control and monitoring.

Observation:

  • A patient developed bilateral proptosis and sepsis one month post-surgery for floor of the mouth tumor resection.
  • Imaging revealed bilateral cavernous sinus thrombosis (CST) secondary to a skull base infection.
  • The patient subsequently experienced sudden bilateral blindness attributed to central retinal artery occlusion and anterior ischemic optic neuropathy.

Findings:

  • This case represents the first documented instance of bilateral blindness as a direct consequence of cavernous sinus thrombosis (CST).

  • Intensive antibiotic treatment improved the patient's critical condition, but the visual loss was permanent.
  • No tumor recurrence was detected, isolating the blindness to the infectious/thrombotic event.

    • Implications:

    • Ophthalmologists and neurologists should consider CST in patients presenting with sudden visual loss, especially after head and neck procedures.
    • Early recognition and aggressive management of skull base infections are crucial to prevent devastating complications like blindness.
    • This case underscores the importance of vigilant monitoring for infectious complications post-reconstructive surgery in the head and neck region.
