This study used a form of peripheral vision testing, called kinetic perimetry, which is effective in detecting peripheral field defects typical of VGB toxicity, and produces more reliable results in children.
Goldmann stimuli sizes and all stimuli colors used in perimetry.
"This research will produce a deeper scientific understanding of perimetry and will lead to improved methods for using perimetry in clinical studies, treatment trials and care of individual patients," Swanson said.
Regular perimetry tests are also used to monitor whether or not treatment for glaucoma is preventing further vision loss.
Swanson's research path will now move toward optimizing and reducing variability in the perimetry testing that is used to find certain patterns of vision loss, especially early changes in vision caused by nerve damage from glaucoma.
This frequency is lower than previous observations using kinetic perimetry in older children or adults.
With a new quantitative model for creating statistical methods that accurately compare different clinical measures, along with development of a next generation of perimetry for glaucoma patients called contrast sensitivity perimetry (CSP), Swanson's work can focus on optimizing protocols for CSP testing in clinics, on testing the new model's predictions in a large database and on developing a better understanding of the relations between how glaucoma damage is measured by CSP and other clinical methods.
