Patient: 46 years of age, female, BCVA 0.08 at OD, 1.0 at OS. Ocular Medical History: acute onset of painless visual loss in her right eye. General Medical History: arterial hypertension, no history of amaurosis fugax, diabetes mellitus, coronary artery disease, or stroke. Main Complaint: sudden loss of vision. Purpose: to present perfused cilioretinal artery in central retinal artery occlusion. Methods: Colour Photography Posterior Pole, FFA, OCT-Spectralis. Findings: Colour Photography Posterior Pole: retinal pallor typical of central retinal artery occlusion , no visible arteriolar embolus, red area in parafoveal area. FFA, 10 s: no arterial filling in the area of central retinal artery, regular filling of the cilioretinal artery FFA, 19 s: late retrograde filling of venous retinal vessels. OCT-Spectralis: segmental focal thickening with hyperreflectivity due to intraretinal edema, regular retinal thickness in area of patent cilioretinal artery. Discussion: Retinal arterial occlusions (CRAO) occurs secondary to an emboli, which may originate from atheromatous plaques in the ascending aorta or carotid arteries, as well as calcified heart valves. Brown et al. (1) reviewed a series of 107 cases with central retinal artery occlusions (CRAO). 26% showed a macular sparing owing to a patent cilioretinal artery. Patients with patent cilioretinal sparing regained variable degrees of visual acuity. CRAO without cilioretinal sparing rarely regained any useful vision. Literature (1) Brown GC, Shields J.
