Causes of RPON
Although it is confirmed that RPON is not a type of migraine, there are still a lot of questions about this condition. The cause of RPON is currently unknown. Researchers suggest that it might be caused by nerve problems, such as nerve compression, loss of protective fatty tissue around the nerves, or a lack of blood flow to the nerves. However, this is only a theory.
Many people with RPON have migraines. Medical researchers don’t know the link between RPON and migraine, but having a migraine history is considered a risk factor for developing RPON. Other risk factors of RPON include being a child, a woman, or having a family history of migraine.
