    Abstract:
    BACKGROUND: Retinal artery occlusion is a vascular entity caused by the temporary blockage of retinal arterioles. CASE PRESENTATION: We present the case of a 57-year-old woman a partial visual loss in the right eye due to a cilioretinal artery occlusion. Ophthalmoscopy revealed a focal area of retinal whitening superior to the optic nerve in the right eye, while the left eye was within the limit. Retinal imaging, in particular optical coherence tomography angiography (OCTA), showed a capillary drop out of the superficial capillary plexus and the corresponding b-scan showed a round hyporeflective grey dot (optical empty) corresponding to the dark grey spot on the enface view at the level of the retinal whitening area. CONCLUSION: Although the images did not allow the differentiation between vasospasm or retinal emboli, the OCTA imaging might help to identify and to caught in the act the specific region causing the retinal impairment. Also, the possible formation of small microcavity should be considered in case with branch retinal artery occlusion. The use of this new imaging technology might help to evaluate the efficacy of the therapy in vivo.
