A study comparing Pulsar perimetry with frequency doubling technology, scanning laser polarimetry and Heidelberg Retina Tomography found that its results were comparable with the other measuring instruments, but agreement between the instruments was rated as "poor to fair."
"Pulsar T30W test is a rapid and easy perimetric method, showing higher sensitivity than [standard automated perimetry] in detecting early glaucomatous [visual field] loss," the authors said. "Its diagnostic ability is good for detecting early perimetric [primary open-angle glaucoma] eyes and fair for [glaucomatous optic neuropathy] eyes."
The prospective observational cross-sectional case study looked at 87 ocular hypertensive patients, 67 glaucomatous optic neuropathy patients, 75 primary open-angle glaucoma patients and 90 normal patients.
Standard automated perimetry HFA 30-2, Pulsar T30W, FDT N-30, HRT II and GDx VCC were performed on the patients.
The study found that Pulsar perimetry seemed to be significantly better than HRT and GDx in detecting primary open-angle glaucoma eyes and comparable with FDT. In glaucomatous optic neuropathy cases, the Pulsar perimetry had better detection results than GDx, but worse than both FDT and HRT.
