Humphrey Automated Visual Field |
|
 Your peripheral vision, or side vision, is
very important for your visual function, and is also affected by
many eye conditions. |
|
Many times, subtle changes in your peripheral
vision are not noticed. The Humphrey Automated Visual Field allows
us to detect any vision loss that you may not have noticed
otherwise. |
|
This is important for conditions such as
Glaucoma,
retinal detachments, optic neuritis, retinal blood vessel
blockage, brain tumors, ptosis (lid lag), auto-immune conditions
like lupus, and many others. |

Sitting in front of a concave dome, a
computer-driven program flashes small lights at
different locations within the dome's surface, and you
press a button when you see the small lights in your
peripheral vision. Your responses are compared to
age-matched controls to determine the presence of
defects within the visual field. The test will detect any
loss of peripheral vision and provide a map of that loss
which will be helpful in diagnosing the cause.
Normal Results
The peripheral vision is normal in extent.
What Abnormal Results Mean
Abnormal results may indicate diseases or central
nervous system problems such as tumors that damage or
compress the parts of the brain that deal with vision.
Other diseases that may affect the visual
field of the eye include diabetes, hyperthyroidism (a
condition where the thyroid produces an excess of
hormones), hypertension, diseases of the pituitary
gland, and multiple sclerosis. |
