A simulation found long-term VF variability is hard to assess clinically, but intensive short-term testing quickly and reliably estimates variability and reliability, unaffected by progression.

Frontloading two visual field tests per visit decreases longitudinal variability in glaucoma monitoring, potentially improving detection of real change and meeting testing frequency recommendations.

Phu Jack, Wang Henrietta, Masselos Katherine, Tan Jeremy C K, Patel Nimesh B, Agar Ashish et al.

Frontloaded visual field testing (two per visit) detected over twice as many glaucoma progressors earlier than standard testing, enabling earlier intervention to preserve vision.

This review explored standard automated perimetry's issues in glaucoma/retinal diseases. It found optimizing parameters and reconciling subjective responses can improve defect detection and structure-function correlation, enhancing clinical care.

This study found SITA Faster provides similar visual field results to other SITA algorithms, but may not be interchangeable in severe glaucoma. False positives are key reliability concerns, and the 24-2C grid helps detect central defects.

This review found early/intermediate AMD significantly reduces mesopic/scotopic retinal sensitivity, especially with MP-1/MAIA devices, providing clinically relevant measures for disease monitoring.

Tan Jeremy C K, Agar Ashish, Kalloniatis Michael, Phu Jack

SITA-Faster visual field variability increases with worsening sensitivity and is stable over time. This means clinicians should interpret results considering disease severity and location, and false-positive cutoffs may need re-evaluation.

Trinh Matt, Kalloniatis Michael, Alonso-Caneiro David, Nivison-Smith Lisa

This study found intermediate AMD features like drusen, pigmentary changes, and reticular pseudodrusen cause distinct, often superior/central, retinal sensitivity loss patterns. This highlights that structural imaging alone underestimates functional visual impairment in iAMD.

Tan Jeremy C K, Phu Jack, Go Denise, Nguyen Doan, Masselos Katherine, Bank Allan et al.

Frontloaded SITA-Faster visual fields consistently confirmed glaucoma defects and identified new ones, offering repeatable data faster than SITA-Standard. This can improve progression monitoring.

High-density OCT revealed early/intermediate AMD causes widespread, unique thickness changes across all retinal layers, with poor interlayer correlation, highlighting the need for comprehensive retinal assessment.

This study found specific displacement models accurately estimate retinal ganglion cell counts from OCT-derived GCIPL thickness, enabling better glaucoma diagnosis and monitoring via commercial OCT.

Tong Janelle, Phu Jack, Alonso-Caneiro David, Khuu Sieu K, Kalloniatis Michael

This study found Drasdo displacement improved central structure-function concordance using GCIPL thickness data, but not deviation maps, offering potential for better glaucoma detection.

Phu Jack, Kalloniatis Michael

This study found that common visual field reliability criteria (false positives, seeding point errors) often lead to unnecessary test exclusion. Censoring low sensitivity points improves reliability, guiding better clinical interpretation.

Phu Jack, Masselos Katherine, Sullivan-Mee Michael, Kalloniatis Michael

Studying glaucoma suspects, more frequent, less stringent risk-based reviews led to more diagnoses, fewer visits, and lower costs, especially within 2.5 years, improving diagnostic efficiency.

Phu Jack, Kalloniatis Michael

This study found performing two visual field tests per visit, especially every 6 months, significantly improves early detection of glaucoma progression and reduces vision loss at detection compared to one test.

Trinh Matt, Khou Vincent, Kalloniatis Michael, Nivison-Smith Lisa

OCT showed intermediate AMD eyes have central RPE-BM thickening but outer and inner retinal thinning, suggesting distinct anatomical changes. This helps target AMD diagnosis and monitoring.

Phu Jack, Kalloniatis Michael

Performing two SITA-Faster visual fields in one visit is viable, yielding reliable, repeatable data in under 20 minutes for most. This helps confirm glaucoma defects and progression efficiently.

Phu Jack, Kalloniatis Michael

Comparing 10-2 and 24-2C visual fields, the 10-2 test better characterized central defects and showed stronger structure-function correlation, making it superior for detailed central glaucoma assessment.

Luu Wilson, Zangerl Barbara, Kalloniatis Michael, Palmisano Stephen, Kim Juno

This study found central vision loss (AMD) enhances self-motion perception, while peripheral loss (glaucoma) reduces it, offering insights into how different visual field defects impact spatial awareness and balance.

Phu Jack, Kalloniatis Michael

This study found seeding point errors (SPEs) cause many unreliable visual field tests, particularly with SITA-Faster. A model was developed to identify SPEs early, improving test reliability and guiding retesting.

Phu Jack, Kalloniatis Michael

The 24-2C visual field test better identified central defects and improved structure-function concordance in glaucoma, but many 24-2C points fell outside standard macular OCT scans.

Trinh Matt, Tong Janelle, Yoshioka Nayuta, Zangerl Barbara, Kalloniatis Michael, Nivison-Smith Lisa

Intermediate AMD eyes showed non-uniform macula ganglion cell layer changes, with more thickening than thinning, varying by location. This aids understanding and monitoring GCL pathologies.

Phu Jack, Khuu Sieu K, Agar Ashish, Kalloniatis Michael

SITA-Faster saves time but has more unreliable results (false positives) and higher sensitivities, especially with field loss, meaning results aren't directly interchangeable with SITA-Standard.

Tong Janelle, Phu Jack, Khuu Sieu K, Yoshioka Nayuta, Choi Agnes Y, Nivison-Smith Lisa et al.

This study modeled age-related macular GCL changes, finding decline starts in the late 30s. Combining spatial clustering and age-correction improved visual field prediction, aiding early glaucoma detection.

Yoshioka Nayuta, Zangerl Barbara, Phu Jack, Choi Agnes Y J, Khuu Sieu K, Masselos Katherine et al.

This study found smaller visual field stimuli (GI-GII) better correlate central retinal structure (ganglion cells) and function in normal and early glaucoma eyes, suggesting this relationship is governed by ganglion cell density.
