She was watching television last night when she covered her left eye due to an itch and discovered that she could not see. The patient denies any precipitating event, pain, swelling, flashes, floaters, or headaches. Her past medical history is significant for uncontrolled hypertension and angina. Her medications include hydrochlorothiazide, lisinopril, atorvastatin, and nitroglycerin as needed. Her physical examination is unremarkable. Fundus examination demonstrates generalized pallor and slight disc edema with no hemorrhages. What is the most likely explanation for this patients symptoms?? A: Acute increase in pressure of the eye, B: Detachment of the retina, C: Inflammation of the temporal artery, D: Occlusion of the ophthalmic artery by embolus, E: Optic neuritis,  <response>: This is a clinical case scenario about a 58-year-old woman who suddenly lost vision in her right eye. The key findings are:- Sudden loss of vision in the right eye without pain or other symptoms- History of uncontrolled hypertension and angina cardiovascular disease- Fundus exam shows generalized pallor and slight disc edema of the right eyeThe diagnosis should explain the sudden unilateral vision loss in a patient with cardiovascular risk factors. Choice A can cause acute vision loss but is unlikely without pain or other symptoms. Choice B also typically has additional symptoms like flashes. Choice C may cause vision loss but would not explain the fundus findings. Choice E could cause unilateral vision loss but optic neuritis is unlikely given the patients age and lack of pain. Choice D, occlusion of the ophthalmic artery by embolus, seems most likely. Ophthalmic artery occlusion can present with sudden painless monocular vision loss and fundus findings consistent with ischemia. The patients cardiovascular disease predisposes her to embolic events.D: Occlusion of the ophthalmic artery by embolus
