What happens when your left eye is suddenly blind?

The sudden blindness of the left eye may be related to factors such as central retinal artery spasm, sudden increase in intraocular pressure, retinal detachment, etc.

1. Central retinal artery spasm

When the left eye is in a state of long-term fatigue, it may cause occlusion of the central vein, resulting in blood circulation unable to reach the eye, thus causing sudden blindness of the left eye.

2. Sudden increase in intraocular pressure

When the intraocular pressure suddenly increases, it will cause acute glaucoma, causing optic nerve edema to oppress the fundus blood supply, and left ischemia will cause sudden blindness of the left eye.

3. Retinal detachment There

are all visual cells in the eye. When the retina of the left eye detaches, there will be symptoms of visual field defect, and in severe cases, sudden blindness of the left eye occurs.
