Is the blind spot enlarged in early glaucoma?
We conclude that enlargement (“baring”) of the blind spot in early glaucoma, as shown by perimetry, is probably not due to a loss of sensitivity around the optic nerve head but to a “topography-effect”. This baring should therefore be considered a pseudo-en- largement or a perimetric side effect.
How big should your blind spot be?
The brain gathers information from the opposite eye and combines it with spatial information to fill in the missing area. The blind spot is positioned at approximately 12 to 15 degrees temporally and 1.5 degrees below the horizon. It measures around 7.5 degrees high and 5.5 degrees wide.
What is optic disc swelling?
Papilledema is swelling of your optic nerve, which connects the eye and brain. This swelling is a reaction to a buildup of pressure in or around your brain that may have many causes. Often, it’s a warning sign of a serious medical condition that needs attention, such as a brain tumor or hemorrhage.
