physiological blind spot
In healthy eyes, are the physiological blind spots always identical or can there be some variation in size?
MEDICAL PROFESSIONAL
The blind spot is caused by the optic nerve head not having sight receptors on it. The optic herve head is towards the nose so the blind spot is projected outward (temporal) towards the ears. Since optic nerve size varies the blind spot varies among normal individuals and can be pathologically small (optic nerve hypoplasia) or abnormally large (swollen optic nerve or papilledema). So yes blind spots vary in size.

Thank you doctor. Do they also vary between eyes in the same individual or are they symmetrical?
