octopusGlaucoma is a condition where nerve damage in the back of the eye leads to changes in the field of vision. By the time the central vision is affected, glaucoma is already far advanced with almost all peripheral vision permanently lost. That is why glaucoma is called the 'sneak thief of vision'. When we test vision on an eye-chart, only the central vision gets tested. So reading 20/20 on the eye-chart would mean you have great central vision, but no comments can be made about the peripheral field of vision.

 
Mt Tam Vision Center uses an Octopus 123 to test your peripheral and central vision, what we call fields. This automated projection perimeter shines a spot of light onto the back of the eye at predetermined locations and intensities. You are asked to press a button when you see the stimulus. Your responses are analyzed statistically and compared with a database of people your age, both with and without various conditions.
 
Besides Glaucoma, numerous conditions such as stroke, other vascular problems, and many neurological conditions can be quickly assessed through Visual Field Testing. Retinal disorders such as Retinitis Pigmentosa  and Retinal Detachment can also be diagnosed and monitored by this technology.
