Endoscopic sinus surgery can cause orbital complications. Unequal pupils after surgery are usually due to eye drops, not serious injury.

Area of Science:

  • Otolaryngology
  • Ophthalmology

Background:

  • Chronic sinus disease management often involves endoscopic sinus surgery.
  • This surgical approach carries inherent risks of orbital complications.

Observation:

  • Orbital complications can include nasolacrimal duct damage, extraocular muscle injury, intraorbital hemorrhage/emphysema, and optic nerve damage.
  • An unequal pupil post-surgery is a significant concern.

Findings:

  • The most common cause of unequal pupils after endoscopic sinus surgery is topical contamination with mydriatic eye drops.
  • This is typically a pharmacological effect, not indicative of severe orbital trauma.

Implications:

  • Understanding the cause of pupillary asymmetry is crucial for accurate diagnosis.
