Retinal artery occlusion is an acute-onset eye disease that seriously impairs vision, and is a critical condition in ophthalmology. The effect of traditional ophthalmology treatment methods are not ideal. It is difficult to recanalize blocked blood vessels early, but thrombolysis can be given within an effective time window to dissolve the thrombus, improve retinal blood perfusion and restore the function of the retinal inner layer cells. Under the protection of the green channel for stroke, we performed intravenous thrombolysis for patients with branch retinal artery obstruction, and achieved satisfactory results, and the patients were cured.
