The Individualised Perimetry Progression Observations in Glaucoma Study (IPPOGS) is a three year longitudinal study that is evaluating the performance of our new visual field testing procedures to improve the detection of changes to vision due to glaucoma.
Glaucoma is a disease of the optic nerve in which the peripheral vision is lost. Visual damage in glaucoma is typically measured using a visual field test, which measures the ability to see small white-light targets at various locations spread across the visual field. Current clinical visual field tests use the same test pattern for all people with glaucoma regardless of what is already known about the person’s vision. IPPOGS will determine whether tailoring visual field tests to the specific individual being tested enables earlier detection of progressive damage to the visual field, enabling quicker decisions about necessary changes to treatment to preserve further sight loss.
In addition to visual field assessment, IPPOGS is also using state-of-the-art retinal imaging methodologies (structural and vascular) and will determine whether personalised visual field tests combined with information from retinal imaging are more helpful in identifying glaucoma progression. Modern sophisticated data analytics approaches are a hallmark of the IPPOGS study in collaboration with the Lions Eye Institute Data Analytics Group.
