Question
My childhood friend returned to her hometown after seven or eight years. We ran into each other in high school, and she took me to her house for a visit. To my surprise, there was a younger brother there with poor eyesight. When she sent me out, I asked her about it, and she said her brother had optic nerve atrophy. How is optic nerve atrophy caused?
Answer
The causes of optic nerve atrophy are quite complex and cannot be attributed to certain inevitable pathogenic 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 conditions of brain edema and choking. The main causes of optic nerve atrophy include:
- Compressive optic nerve atrophy.
- Ischemic optic nerve atrophy.
- Inflammatory optic nerve atrophy.
