Why does Crvo cause macular edema?
[1] The pathogenesis of CRVO is believed to involve vascular endothelial damage and compression of the retinal vein, leading to thrombus formation. This leads to increased retinal capillary pressure, which causes transudation into the extracellular space and macular edema.
What is macular edema following retinal vein occlusion?
RVO occurs when a blood vessel in the retina becomes blocked, often by a blood clot. When fluid leaks into the macula as a result of the blocked blood vessel, it is called Macular Edema following Retinal Vein Occlusion, or MEfRVO.
Can macular edema cause retinal detachment?
Macular edema with extensive serous retinal detachment around macula and optic disc area were observed the first day after surgery. Without surgical intervention, a quick recovery of the macular edema and retinal detachment was observed by spectral domain optical coherence tomography 1 week later in both cases.
Can retinal occlusion be cured?
There’s no cure for retinal vein occlusion. Your doctor can’t unblock the retinal veins. What they can do is treat any complications and protect your vision.
What is the best treatment for branch retinal vein occlusion?
While BRVO cannot be cured, there are effective treatments that can help patients maintain or improve their visual outcome by reducing the associated macular edema. Treatment options include intravitreal injection (injection of medicine into the eye) and laser.
What is the prognosis for someone with retinal vein occlusion?
The prognosis for retinal vein occlusion depends on the subtype of occlusion that is present, but patients are typically monitored for potential complications. The eye has only one vein with multiple branches, and when that vein or one of the branches is blocked, blood flow backs up and stagnates.
What tests are used to diagnose retinal vein occlusion?
Sometimes, you may also need a test called optical coherence tomography. You may get drops to dilate your pupils and then a machine scans your eyes with rays of light to make a detailed image of your retina. There’s no cure for retinal vein occlusion.
How will your doctor diagnose retinal vein occlusion?
How to diagnose central retinal vein occlusion Fluorescein angiography: Use of a special camera to take a series of photographs of the retina after a small amount fluorescein (yellow dye) is injected into a vein in your Optical coherence tomography (OCT): Used to assess for macular edema and monitoring its course Intraocular pressure measurement Reflexes of the pupil Photos of the retina
What is the treatment for retinal vein occlusion?
Treatment options for retinal vein occlusions include laser surgery and intraocular injections of medications that prohibit abnormal blood vessel growth (anti-VEGF drugs) and anti-inflammatory agents (corticosteroids).
