Summary
A rare case of superonasal retinal arterial occlusion and temporal visual field loss occurred after routine vitrectomy surgery. Prompt diagnosis is key, as the artery may reperfuse, leaving subtle signs.
Area of Science:
- Ophthalmology
- Retinal Vascular Diseases
- Surgical Complications
Background:
- Pars plana vitrectomy is a common ophthalmic procedure.
- Gas-fluid exchange is frequently used during vitrectomy.
Observation:
- A case report details a patient experiencing superonasal retinal arterial occlusion.
- This occlusion resulted in a temporal visual field defect.
Findings:
- Retinal arterial occlusion was noted 12 days post-vitrectomy.
- The affected artery reperfused within 10 weeks.
- Minimal vascular attenuation and mild optic atrophy were observed post-reperfusion.
Implications:
- Even uneventful vitrectomy can lead to peripheral visual field loss due to arterial occlusion.
- Early detection of retinal arteriolar occlusion is crucial.
- Timely examination after intraocular gas resorption may reveal occlusive events.
