Explain briefly about retinal artery occlusion?

Explain briefly about retinal artery occlusion?

See a retina special: A blocked retinal artery (usually from an embolus that traveled from somewhere else in the body like the carotid artery or the heart) can lead to vision loss. It could be a branch or the central retinal artery. There are no good treatment, but a systemic workup to look for the source is required (carotid ultrasound and echocardiogram). A rarer cause is giant cell arteritis. ...Read more

Obstruction (Definition)

Anything that creates a blockage of the intestinal tract. You may think of the intestinal tract (stomach, small bowel, large bowel) as somewhat akin to a garden hose. If you kink the garden hose, or twist it, or block it inside, you have created an "obstruction". Most obstructions are a results of previous surgery and most of these ...Read more

Is central retinal artery occlusion correctible, and if so, then how much time do you have?

Is central retinal artery occlusion correctible, and if so, then how much time do you have?

Not correctable : Occlusion of the vessel can occur from a plaque, clot, emboli, irregular heart beat, etc. Eye can worsen (glaucoma/pain) even if vision improves some, which is rare. The important task to do is to prevent more events in eyes and brain, see your family doctor to determine what caused this occlusion. ...Read more

Can you give me suggestion: any treatment/surgery for central retinal artery occlusion?

Medical evaluation: Most importantly, you must get an immediate, comprehensive medical evaluation to find possible causes and treat them. This is not a purely ocular problem - the underlying causes must be found. As far as visual recovery is concerned, certain treatments, such as hyperbaric oxygen and intraocular pressure lowering, can help if done very promptly. ...Read more

Asd closure after retinal artery branch occlusion. Post procedure = palpitations that felt very irregular. After 6 weeks it improved. My dr thinks i may be in af. Is it possible that af was transient?

Asd closure after retinal artery branch occlusion. Post procedure = palpitations that felt very irregular. After 6 weeks it improved. My dr thinks i may be in af. Is it possible that af was transient?

A fib: Yes. It is possible in case of paroxysmal atrial fibrillation, which is episodic. As you have mitral regurgitation, you are at risk for having atrial fibrillation. As you are already on Aspirin and Plavix (clopidogrel) i don't recommend warfarin which increases bleeding risks. I suggest you to get holter and event monitor to record arrhythmias to get appropriate antiarrythmic therapy. ...Read more

What are the differences between ischaemic optic neuropathy and retinal artery occulsion?

What are the differences between ischaemic optic neuropathy and retinal artery occulsion?

Difficult to answer: If one distinguishes between anterior and posterior ischemic optic neuropathy this is easier to answer as the former is almost always caused by giant cell arteritis and treated with prednisone and the latter is due to systemic atherosclerosis. Acute central retinal artery occlusion may be caused by carotid occlusion or dissection or cardioembolic events. Treatment includes hyperbaric O2. ...Read more

What is the difference between optic neuropathy and retinal artery occulsion?

What is the difference between optic neuropathy and retinal artery occulsion?

Related issues: Optic neuropathy is a generic term referring to damage to the optic nerve from any cause including trauma, decreased blood flow, or genetic disease. Retinal artery occlusion is a blockage in the artery feeding the retina, which leads to damage or death of the retinal nervous tissue. A central retinal artery occlusion can cause an optic neuropathy. ...Read more

Can you please tell me how ischaemic optic neuropathy and retinal artery occulsion differ?

Can you please tell me how ischaemic optic neuropathy and retinal artery occulsion differ?

Nerve vs. artery : Arterial occlusion generally from embolus, inflammatory, which affects the inner retinal lining of the eye. Ischemic optic neuropathy is due to blockage of the blood flow to the optic nerve (anterior ciliary arteries or posterior nutritive). Other causes can be from compression form tumors or inflammation as in giant cell arteritis. ...Read more

Please tell me, could hereditary retinal artery tortuosity be cured?

Please tell me, could hereditary retinal artery tortuosity be cured?

No. It is inherited: Hereditary conditions are by definition genetically inherited. However recent research into stem cell treatment of inherited conditions of the eye are beginnjng to be treated and studied Retinal tortuosity can also be caused by carbon monoxide exposure. You would benefit from habing your car muffler checked by your mechanic for leaks and see your ophthalmologist. ...Read more

Artery (Definition)

Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more
