My brother was recently diagnosed with papilloedema in both eyes, greater in the left eye. What could this mean? Is this life-threatening? Can you live with this? He had some vision changes which led him to see an opthamologist who gave him new glasses and this diagnosis. He's going to see a retinologist to look further into it later in the week. I've heard it could be a tumor. Is it possible to be something else? With a tumor wouldn't he be acting differently? He seems otherwise fine, despite his change in vision. Are any of you living with this? What are the treatments? Is this a very concerning condition? I'm not sure what to think!
