Summary
Pars plana vitrectomy with air/fluid exchange can cause permanent visual field defects. Surgeons should exercise caution during optic nerve procedures to prevent optic nerve trauma.
Area of Science:
- Ophthalmology
- Surgical Procedures
- Neuroscience
Background:
- Pars plana vitrectomy is a common intraocular surgery.
- Air-fluid exchange is frequently used during vitrectomy to maintain intraocular pressure and tamponade the retina.
Observation:
- Three patients developed dense, permanent, peripheral temporal visual field defects post-vitrectomy.
- These defects were observed in the eyes treated with pars plana vitrectomy and air/fluid exchange.
Findings:
- Visual field loss is a potential complication following pars plana vitrectomy with air/fluid exchange.
- Mechanical trauma to the optic nerve head during the procedure may cause this visual field defect.
Implications:
- Ophthalmic surgeons must be cautious when using extrusion instruments near the optic nerve.
- This finding highlights the need for careful surgical technique to minimize the risk of optic nerve damage and subsequent visual field loss.
