Sudden onset painless loss of vision in an old patient with thromboembolic risk factors without temporal headache + pale retina = Central Retinal Artery Occlusion
Though there are many tried treatment options in CRAO (such as AC paracentesis/ ocular massage), we don’t have an effective one. But different centres have their own protocols. The prime goal of CRAO is to assess the risk for STROKE in the brain, as CRAO is the stroke of the eye. So, it’s essential to refer the patient to the Stroke clinic and to treat the cardiovascular risk factors.
In severe cases, we can expect RAPD in retinal diseases such as CRAO, CRVO, Retinal detachment etc. since Retina is a part of the afferent visual pathway. So optic nerve lesions and severe retinal disorders can cause RAPD
