Branch retinal artery occlusion in a patient with one eye. Laser Nd:YAG approach. / Oclusión de rama arterial retiniana en un paciente con ojo único. Abordaje mediante láser Nd:YAG.

CLINICAL CASE: An 82-year-old man was admitted to the emergency department complaining of a sudden painless visual loss in his left eye (OS). He was diagnosed with branch retinal artery occlusion (BRAO) with a visible embolus. In 2012, he had a central artery occlusion (CRAO) in his right eye (OD). An embolysis with Nd:YAG laser was attempted, the retinal arterial blood flow was restored completely and the visual field was improved, with no secondary complications. CONCLUSIONS: Nd:YAG laser embolysis is a treatment to be considered in patients with BRAO with a visible embolus. The risks and benefits of the procedure should be evaluated, comparing it with possible permanent loss of visual acuity and other vascular complications caused by BRAO.
