The correct answer is to administer high-flow oxygen via non-rebreather mask. In cases of suspected retinal artery occlusion, immediate high-flow oxygen therapy is crucial. This intervention aims to maximize oxygen delivery to the retina, potentially preserving some retinal function until definitive treatment can be initiated. The cherry-red spot in the macula is a classic sign of retinal artery occlusion.

While ophthalmology consultation is important, it is not the most immediate intervention. Ocular massage may be attempted but is less effective than oxygen therapy. Administering aspirin is part of the management but is not the most urgent step. High-flow oxygen therapy should be initiated immediately while preparing for other interventions and specialist consultation.
