Utilization trends: visual field testing and ocular imaging in open-angle glaucoma

“169,917 individuals with OAG and 395,721 with suspected glaucoma age ≥40 enrolled in a national United States managed care network between 2001–2009.” (opens the source at this quote in a new tab)
“For patients with OAG, the odds of undergoing VF testing decreased by 36% from 2001 to 2005, 12% from 2005 to 2009, and 44% from 2001 to 2009. By comparison, the odds of having OOI increased by 100% from 2001 to 2005, 24% from 2005 to 2009, and 147% from 2001 to 2009.” (opens the source at this quote in a new tab)
“The probability of undergoing OOI increased from 26% in 2001 to 47% in 2009 for patients of optometrists and from 30% in 2001 to 46% in 2009 for patients of ophthalmologists.” (opens the source at this quote in a new tab)

Geographic variation in diagnostic testing after open-angle glaucoma diagnosis
