A rare complication of optic nerve sheath fenestration (ONSF) surgery is choroidal infarction, which can cause visual field loss. Diagnosis may be delayed as funduscopic signs appear weeks post-surgery.

Area of Science:

  • Ophthalmology
  • Surgical Complications
  • Neuro-ophthalmology

Background:

  • Optic nerve sheath fenestration (ONSF) is a surgical procedure to decompress the optic nerve.
  • While generally safe, potential complications require careful monitoring and understanding.

Observation:

  • Two patients developed visual complications following ONSF surgery.
  • These complications included significant temporal visual field depression and characteristic nasal fundus changes.

Findings:

  • Both patients experienced choroidal infarctions as a direct result of ONSF.
  • The observed funduscopic changes included wedge-shaped subretinal pigmentation.

Implications:

  • Choroidal infarction is a potential complication of ONSF that can lead to visual field deficits.

  • Ophthalmologists should consider this diagnosis in patients with unexplained visual field loss post-ONSF.
  • Diagnostic funduscopic signs may not manifest immediately, necessitating delayed evaluation.
