Retinal vessel occlusion

Alternative Names: Retinal vein occlusion; Retinal artery occlusion Treatment: The dilation of retinal vessels by inhalation of carbon dioxide/oxygen mixtures may be used to treat arterial blockages. This treatment may allow the clot to move further down the vessel, thereby reducing the area of the retina that is affected. Text Continues Below In retinal artery occlusion, the cause of the blockage should be investigated. These blockages may reflect life-threatening medical situations. Patients with retinal artery occlusions should be evaluated by their primary care provider for the presence of hypertension, valvular heart disease, or carotid artery blockage. Treatment for retinal vein occlusions can include aspirin and laser therapy. In patients under 40, blood work investigating a clotting problem should be considered. Diligent evaluation of the blockage over months is important, since many harmful effects take 3 months or more to develop. Expectations (prognosis): The outcome varies. Retinal arterial blockages have a poor prognosis for visual recovery, while patients with retinal vein occlusions often regain excellent sight. Complications: Stroke Glaucoma Partial or complete loss of vision in the affected eye Calling your health care provider: Call your health care provider if sudden blurring or loss of vision occurs.
