Nd YAG Laser Embolysis in a Young Woman with Hemiretinal Artery Occlusion.

Retinal artery occlusion is an uncommon condition but can lead to grave consequences if not managed in time. Elderly population with other comorbid conditions like hypertension, ischemic heart disease, hyperlipidemia and stroke are commonly affected. However, this condition may affect younger population with entirely different systemic associations. Thromboembolism, which usually takes place secondary to cardiac emboli or hypercoagulable states cause retinal artery occlusion in young population. A24-year lady presented with a short history of unilateral altitudinal visual loss. On examination, she was found to have hemiretinal artery occlusion. Ocular massage, anterior chamber paracentesis was performed initially, followed by Nd YAG laser embolysis, which led to successful restoration of retinal circulation and significant improvement in visual field loss. Detailed evaluation and systemic investigations were carried out to identify the underlying cause, but no systemic association could be found.
