I was diagnosed with PTC in September of 2007. My CSF pressure was 423 at my first lumbar puncture. A week later it was back up to 600, the very next day I was rushed into surgery to have an LP shunt placed to control the pressure. The pressure then, was 560. My shunt is set at 150. My headaches are mostly gone, but my eyes are damaged. My vision is 20/2300. My question is this, Is my CSF pressure too high? I've heard that "normal pressure" is between 7-14. Why would my neurosurgon set mine so high?
