The Individualised Perimetry Progression Observations in glaucoma Study (IPPOS) is a longitudinal study following people with glaucoma every 4 months over 3 years at the [Lions Eye Institute](https://www.lei.org.au). The main novel measurement is an implementation of the ARREST visual field testing approach which adds locations for testing to the visual field without increasing test times. <h3>Key facts</h3> * Commenced October 2023 with scheduled completion late 2027 * Collecting at baseline visit: On-Off Macular Sensitivity, Frequency of Seeing Curves, Quality of Life Survey * Collecting every 4 months on all eyes: ARREST fields, 24-2 fields, OCT, OCTA <h3>Investigators</h3> * Prof Allison McKendrick * Prof Bill Morgan * Prof Andrew Turpin * Dr Vanessa Tang * Dr Vasanth Muthusamy * Dr Geoffrey Chan <h3>Progress</h3> * April 2024: 81 baseline visits complete, 30 second visits complete. * June 2024: 98 baseline visits complete, 50 second visits complete, 9 third visits complete. * January 2025: enrollment complete! All first visit data collected on 140 eyes. <h3>Publications</h3> * Allison McKendrick,Vanessa Tang, Bill Morgan, Geoffrey Chan, Vasanth Muthusamy, Andrew Turpin. *Personalised perimetry: the Individualised Perimetry Progression Observations in Glaucoma Study (IPPOGS)*.
