Embolectomy for branch retinal arterial occlusion

Area of Science:

• Ophthalmology
• Retinal Vascular Diseases
• Surgical Techniques

Background:

• Branch retinal artery occlusion (BRAO) can cause significant vision loss.
• Identifying and removing the embolic source is crucial for treatment.
• Pars plana vitrectomy offers a surgical approach for retinal interventions.

Purpose of the Study:

• To describe the surgical management of BRAO using pars plana vitrectomy.
• To report the outcomes of attempting embolus removal in a BRAO case.

Main Methods:

• A single case of BRAO with a visible embolus was treated.
• Pars plana vitrectomy and attempted arterial embolectomy were performed.
• Pre- and postoperative visual acuity, fluorescein angiography, and OCT were analyzed.

Main Results:

• Embolus removal was unsuccessful; the embolus repositioned intraoperatively.
• Despite failed removal, fluorescein angiography showed improved arterial perfusion.
• Optical coherence tomography revealed reduced macular edema postoperatively.
• Visual acuity improved from 20/80 to 20/20 within 9 months.

Conclusions:

• Vitreous surgery can be considered for BRAO with visible emboli.
• Even unsuccessful embolus extraction may lead to improved visual outcomes.
• Further research into surgical techniques for BRAO is warranted.
