Surgical mobilization of an arterial embolus in cilioretinal artery occlusion

We describe an effective surgical approach for the management of cilioretinal artery occlusion. A 23-G pars plana vitrectomy assisted with two soft tip cannulas was performed. One cannula pressed the cilioretinal artery branch directed toward the macula, distal to the location of the embolus, whereas the other cannula was used to gently swipe over the cilioretinal artery proximal to the occlusion. Anatomical and functional outcomes were evaluated by fundus examination, fluorescein angiography, Goldmann visual field, and best-corrected visual acuity (BCVA). It was possible to mobilize the embolus by mechanical displacement with 23-G soft-tip cannulas and disintegrate it, preventing the passage toward the branch directed to the macula. Restoration of retinal circulation was confirmed by fluorescein angiogram. The patient recovered his previous documented BCVA and visual field. The described technique can be considered as a new possibility for achieving a solution to cilioretinal artery occlusion or any other retinal artery occlusion.
