Idiopathic recurrent branch retinal arterial occlusion

Area of Science:

• Ophthalmology
• Vascular Medicine
• Medical Research

Background:

• Recurrent branch retinal arterial occlusions (BRAO) are uncommon, particularly in healthy individuals.
• The etiology of BRAO is often unknown, posing diagnostic challenges.

Observation:

• Nine seemingly healthy patients presented with recurrent, multiple BRAOs.
• Three patients reported associated auditory symptoms; others showed no systemic vascular disease signs.

Findings:

• Ophthalmoscopic and fluorescein angiography suggested focal arteritis and arteriolitis as the cause.
• The inflammatory process appeared localized to retinal vessels.

Implications:

• This suggests focal arteritis/arteriolitis as a potential, albeit rare, cause of BRAO in young, healthy individuals.
• Early recognition and further investigation may be warranted in similar cases to understand underlying mechanisms and optimize management.
• Despite the severity of BRAO, visual prognosis can be favorable in these specific cases.
