How might hereditary endotheliopathy with retinopathy, nephropathy, and stroke (HERNS) be treated?

At this time there is no effective treatment for hereditary endotheliopathy with retinopathy, nephropathy, and stroke (HERNS). Treatment of HERNS is largely palliative, which means that it is aimed at decreasing pain and suffering by providing treatments for relief of symptoms along with comfort and support. In some cases, aspirin may be recommended. Laser treatment to prevent retinal hemorrhage may be beneficial to some affected individuals. A continuous maintenance dose of corticosteroids may be prescribed to manage cerebral edema (swelling in the brain).[1][2][3]
