Physiological blind spot enlargement
Physiological blind spot enlargement: Because the optic nerve of the human eye is in front of the retina, they gather at a point and pass through the retina to the brain. If an image of an object just falls on this point, it will not be seen, which is called a blind spot. The pseudo-disease that causes the enlargement of the physical blind spot are brain tumors and acute angle-closure glaucoma.
