Lifestyle changes that help to prevent retinal vein occlusion include eating a low-fat diet, getting regular exercise, maintaining an ideal weight and not smoking, according to the National Institutes of Health. Controlling diabetes and taking aspirin or blood thinners can also help prevent retinal vein occlusion.
Retinal vein occlusion is caused by the formation of a blood clot in the veins of the retina and may result in the destruction of retinal cells and vision loss, according to Cleveland Clinic. Although the beginning of the disease is marked with slight blurring or loss of vision, this can worsen over a few hours or days and can sometimes result in a total and abrupt loss of vision or in other eye problems.
Risk factors for retinal vein occlusion include age, atherosclerosis, diabetes, high blood pressure and other eye conditions. Although there is no way to reverse or open blockages, many regain vision without treatment. Treatment for complications of retinal vein occlusion may include focal laser treatment, if macular edema is present, injections of anti-vascular endothelial growth factor drugs into the eye and laser treatment to prevent growth of new abnormal blood vessels that can lead to glaucoma, according to the NIH.
