Pars plana vitrectomy for macular holes can cause inferotemporal visual field defects. This vision loss may result from optic nerve damage during the surgical procedure.

Area of Science:

  • Ophthalmology
  • Surgical Outcomes
  • Neuro-ophthalmology

Background:

  • Idiopathic macular holes are a common cause of vision impairment.
  • Pars plana vitrectomy is a standard surgical treatment for macular holes.
  • Visual field defects are a potential complication of ocular surgery.

Observation:

  • Three patients developed inferotemporal visual field defects after pars plana vitrectomy.
  • Defects were noted early postoperatively in two patients; one was asymptomatic but had perimetry abnormalities.
  • Visual field deficits remained stable over 4-12 months of follow-up.

Findings:

  • Pars plana vitrectomy for idiopathic macular hole is associated with inferotemporal visual field defects.
  • The visual field defect appears to be a persistent complication.

  • Potential causes include inadvertent optic nerve injury during air/fluid exchange or hyaloid membrane stripping.

    • Implications:

    • Ophthalmologists should be aware of visual field defects as a potential complication of pars plana vitrectomy.
    • Further investigation into the mechanisms of optic nerve injury during vitrectomy is warranted.
    • Patients undergoing this procedure should be monitored for visual field abnormalities.
