Question
My childhood friend has returned to her hometown for over seven years. We bumped into each other in high school, and she took me to her house as a guest. To my surprise, there was a younger brother who seemed to have eye problems. When she sent me out, I asked her about it, and she said the brother had optic nerve atrophy. How is optic nerve atrophy caused?
Answer
The causes of optic nerve atrophy are quite complex, and it is impossible to confirm whether certain phenomena are inevitable anemic factors. Generally speaking, ischemic optic nerve atrophy is more common, which is caused by an increase or interruption in the blood supply to the optic nerve due to one or more different diseases, leading to optic nerve atrophy in the presence of brain edema and aspiration. The main causes of optic nerve atrophy are as follows: 1. Compressive optic nerve atrophy. 2. Ischemic optic nerve atrophy. 3. Inflammatory optic nerve atrophy.
