This study found PERG amplitude significantly correlates with macular GCC and RNFL thickness in glaucoma, suggesting PERG reflects inner retinal ganglion cell health, aiding early detection and monitoring.

Vizzeri G, Weinreb R N, Gonzalez-Garcia A O, Bowd C, Medeiros F A, Sample P A et al.

This study found SD-OCT is repeatable, but TD-OCT measures thicker RNFL. While agreement is good, these instruments' measurements are not interchangeable for glaucoma management.

Tannenbaum D P, Zangwill L M, Bowd C, Sample P A, Weinreb R N

This study found significant overlap in nerve fiber layer measurements between large cup-to-disk ratio eyes with and without visual field defects, limiting scanning laser polarimetry's early glaucoma detection utility in these patients.

Sample P A, Johnson C A

Glaucoma visual field defects correlate directly with optic nerve damage, progressing in affected areas. This improves early detection and targeted follow-up, enhancing patient care.

Bowd C, Zangwill L M, Berry C C, Blumenthal E Z, Vasile C, Sanchez-Galeana C et al.

This study compared early glaucoma detection methods, finding OCT and FDT perimetry generally outperformed SLP and SWAP in identifying early disease, suggesting their superior clinical utility.

Sample P A

Glaucoma damages specific optic nerve fiber bundles, causing characteristic visual field defect patterns and progression, which functional tests effectively monitor for individual patient management.

Kono Y, Sample P A, Emdadi A, Weinreb R N

This study found that ranked threshold distribution (RTD) analysis effectively tracks glaucoma progression using SWAP, showing strong correlation with pointwise analysis, especially for visualizing diffuse changes.

Sample P A

SWAP is more sensitive than standard tests for early glaucoma detection and progression, revealing individual ganglion cell subtype differences, crucial for monitoring disease and treatment effectiveness.

Sample P A, Bosworth C F, Blumenthal E Z, Girkin C, Weinreb R N

This study compared various perimetry tests, finding specific tests (FDT, SWAP) detect glaucoma damage earlier and more broadly than standard perimetry, improving early detection and monitoring.

Blumenthal E Z, Sample P A, Zangwill L, Lee A C, Kono Y, Weinreb R N

In stable glaucoma patients, short-wavelength automated perimetry (SWAP) showed higher long-term variability than standard perimetry, especially peripherally. This means SWAP changes require more careful interpretation for disease progression.

Emdadi A, Kono Y, Sample P A, Maskaleris G, Weinreb R N

This study found that parapapillary beta zone atrophy in glaucoma patients with focal visual field loss strongly corresponds with localized optic nerve rim thinning, indicating potential early damage.

Bosworth C F, Sample P A, Williams J M, Zangwill L, Lee B, Weinreb R N

This study found focal motion perimetry visual field defects spatially correlate with focal optic disc thinning, similar to other perimetry tests. This suggests disc damage is independent of the functional test used.

Kono Y, Zangwill L, Sample P A, Jonas J B, Emdadi A, Gupta N et al.

This study found that parapapillary atrophy, especially the beta zone, correlates with worse visual field loss in glaucoma, indicating its clinical utility as a disease progression marker.

Plummer D J, Marcotte T D, Sample P A, Wolfson T, Heaton R K, Grant I et al.

In HIV patients without retinal disease, peripheral visual field loss correlated with poorer neuropsychological function and higher rates of cognitive disorders, suggesting perimetry may indicate HIV-related brain dysfunction.

Emdadi A, Zangwill L, Sample P A, Kono Y, Anton A, Weinreb R N

This study found early focal glaucoma visual field loss can manifest as diffuse, focal, or undetectable optic disk damage, highlighting varied structural presentations for clinicians.

Bathija R, Zangwill L, Berry C C, Sample P A, Weinreb R N

This study found several HRT parameters can detect early glaucoma, with varying sensitivity/specificity, influenced by disc size, aiding clinical diagnosis.

Anton A, Yamagishi N, Zangwill L, Sample P A, Weinreb R N

This study mapped glaucoma's structural (optic disc) and functional (visual field) damage, finding a variable but identifiable topographic relationship, useful for objective damage evaluation.

Mueller A J, Plummer D J, Dua R, Taskintuna I, Sample P A, Grant I et al.

Many HIV-positive patients without visible eye disease show subtle visual dysfunctions (perimetry, contrast, color vision), highlighting the need for comprehensive visual testing beyond acuity.

Sample P A, Irak I, Martinez G A, Yamagishi N

Normal eyes show greater short-wavelength sensitivity inferiorly, increasing with eccentricity, not age. This asymmetry is crucial for interpreting short-wavelength perimetry in glaucoma and other diseases.

Yamagishi N, Anton A, Sample P A, Zangwill L, Lopez A, Weinreb R N

This study found that in glaucoma, focal visual field defects precisely correspond to specific areas of optic nerve damage, highlighting the topographic relationship and utility of rim area ratio for detection.

Zangwill L M, van Horn S, de Souza Lima M, Sample P A, Weinreb R N

This study found ocular hypertensive eyes have optic nerve topography measurements intermediate between normal and glaucoma eyes, aiding in risk assessment and differentiation.

Plummer D J, Sample P A, Arévalo J F, Grant I, Quiceno J I, Dua R et al.

HIV-positive patients without infectious retinopathy showed significant visual field loss, especially on short-wavelength perimetry, indicating a non-infectious retinal issue. This impacts daily living and warrants further investigation.

Weinreb R N, Shakiba S, Sample P A, Shahrokni S, van Horn S, Garden V S et al.

This study found quantitative retinal nerve fiber layer measurements correlate with visual field loss in glaucoma, suggesting these imaging techniques aid in assessing disease severity and progression.

Martinez G A, Sample P A, Weinreb R N

This study compared high-pass resolution and standard perimetry for glaucoma detection. Both tests performed similarly in identifying glaucoma, but high-pass resolution perimetry detected more glaucoma suspects, suggesting its potential as an alternative.

Sample P A, Martinez G A, Weinreb R N

This study found short-wavelength visual field testing can accurately diagnose glaucoma without lens density correction, simplifying testing and reducing patient time by 40 minutes.
