This measures rapid flicker thresholds at the fovea, which is responsible for sharp central vision, as well as at each of the four quadrants of the eye. The Flicker Plus test is extremely efficient as it has standardised stimulus conditions, efficient threshold measuring algorithms and an incredibly sensitive choice of stimulus parameters all running on a calibrated display system that measures five locations simultaneously.
Who can benefit from it
Rapid flicker sensitivity is an important biomarker in glaucoma, multiple sclerosis, diabetes, ARMD and ocular hypertension. Anyone who suffer from any of these health concerns will benefit from taking this test.
Other relevant tests
Taking Flicker Plus together with CAD can give more specific results regarding loss of colour vision through glaucoma or detect subtle changes linked to side effects of accidental exposure to or planned treatment with certain drugs.
