A 25 year old man presents with sudden painless loss of vision. Why?
In any patient with visual loss it is imperative to ask 2 questions.
In this particular patient a dilated examination showed that the patient had significant areas of “cloudy swelling” (this is what ophthalmologists call retinal whitening due to thickening of the superficial axons of the retina). Cloudy swelling is indicative of retinal artery ischemia. This patient was also noted to have some thinning of the retinal artery (the normal vein to artery ratio is 3:2). A chalky-white embolus was noted at the level of the central retinal artery as it exited the optic nerve. The patient was diagnosed with a retinal artery occlusion.
