Due to the different parts of the optic nerve, retrobulbar optic nerve can be divided into many different types: lesions most often invade the optic disc macular bundle fiber, many people can't cure for a long time, not because they can't cure it, but they don't understand it.

matters needing attention
The visual field should be checked regularly. Visual field examination is divided into dynamic and static examination. The general visual field examination is dynamic, which is to measure the points of equal sensitivity with moving visual markers, and the line connected is called equal line of sight, recording the peripheral contour of the visual field. The static examination is to measure the light sensitivity threshold of each point on a meridian line and connect it into a curve to get the concept of depth of visual field defect. Diet light nutrition, pay attention to dietary balance, can eat more food containing vitamin A. Don't eat spicy food.
