PURPOSE:To assess correlation, agreement and diagnostic accuracy of a new tablet-based 24-degree, 52-point online circular contrast perimetry application (OCCP), compared to computer-based OCCP and standard automated perimetry (SAP). METHODS:Seventy-five participants (26 controls, 49 glaucomatous) were tested via SAP using Humphrey field analyzer (Zeiss), then by computer OCCP on a 24-inch monitor, followed by two OCCP tests on a tablet (iPad Air 5th gen). Key outcome measures included pattern standard deviation (PSD), mean deviation (MD), mean sensitivity per point, and visual field index (VFI)/visual index (VI). RESULTS:Agreement and correlation of VFI, PSD, and MD between OCCP tablet and SAP were very strong, with spearman's ρ and intra-class correlation coefficients between 0.81-0.86 and 0.80-0.93, respectively. MD Bland-Altman bias was greater for OCCP tablet against SAP-0.53 to 0.68 dB-compared to OCCP computer against SAP at 0.05 dB. 95% limits of agreement were comparable for OCCP versus SAP. Point-by-point Bland-Altman bias demonstrated tighter agreements between OCCP tablet and OCCP personal computer (PC) compared to OCCP generally and SAP. Receiver-operating-characteristic curves were comparable across outcomes between all OCCP tests, SAP, and cirrus optical coherence tomography parameters with no significant differences. Test duration was longer for OCCP tablet than SAP, whereas OCCP PC was shorter than SAP (p < 0.001). CONCLUSIONS:OCCP tablet has strong correlation, agreement, and similar area-under-curve in identifying glaucomatous eyes from controls to both SAP and OCCP computer, demonstrating prospect as a tool for glaucoma perimetry testing in low-resource settings, with further enhancements to reduce test duration.

PRÉCIS:Online binocular perimetry showed moderate to strong agreement with Esterman visual field testing in glaucoma patients and controls, with high correlation coefficients and predictive capability. This tool may offer a viable, accessible alternative to machine perimeters for driving licence assessment. PURPOSE:To assess the feasibility of an online computer-based binocular driving perimetry assessment (OBDP) based on online circular contrast perimetry, and agreement with binocular static Esterman visual field testing (EVFT). METHODS:A prospective comparative cohort study was conducted on patients with or without open angle glaucoma, recruited from a single-site glaucoma subspecialty practice. Eligible subjects underwent 2 visual field tests using OBDP and this was compared with the results of a single EVFT. RESULTS:Eighty patients were enrolled in the study, with a mean age of 69 years (+/- 13.4 SD). Of these, 49% were female, 18 were healthy controls, while 20, 18 and 24 had mild, moderate and severe glaucoma, respectively. Pearson and intraclass correlation between the 2 perimetry methods for percentage of points not seen (PNS) was 0.85 and 0.86 (95% CI: 0.78-0.9), respectively, for the overall binocular visual field. When the binocular field was subdivided into 8 sectors, intraclass coefficients (ICCs) ranged from 0.76 to 0.93 for each sector. Bland-Altman analysis revealed a difference of 1.24% (95% CI: -16.93% to 19.30%) between the 2 methods for the overall field, ranging from 0.04% to 4.17% for each sector. On the basis of the Austroads fitness to drive guidelines, OBDP demonstrated a sensitivity of 96.97% and specificity of 78.57% when compared with the EVFT. ICCs evaluating the repeatability of OBDP testing for the percentage of PNS were excellent overall (0.97) and ranged from moderate to excellent for each of the 8 sectors (0.67-0.98). CONCLUSION:OBDP showed strong agreement with EVFT. As an online application that easily runs on any computer, it could expand the scope of binocular perimetry screening for licence assessment. With modifications, integration into modern clinical licensing procedures could be considered.

PURPOSE:Patient-centered care is key to successful clinical outcomes and meaningful clinician-patient relationships. Accordingly, a comprehensive understanding of patient perspectives is essential to aligning the clinician's focus and patient's goals. However, our understanding of patients' perceptions of glaucoma surgery and involvement in surgical decision-making has not kept pace with the rapid treatment advances in the field and move toward earlier surgery with the advent of minimally invasive glaucoma surgery devices. The purpose of this study was to understand the perspectives and priorities of people with glaucoma when considering glaucoma surgery through qualitative analysis of semistructured interviews. DESIGN:A qualitative study. PARTICIPANTS:Individuals diagnosed with glaucoma, above 18 years of age, and able to communicate effectively in English. Interviews were conducted with 40 participants: 23 participants who had undergone glaucoma surgery and 17 who had not. METHODS:Interviews were conducted over telephone, using an interview guide developed in consultation with people with glaucoma and surgeons. The cohort was purposely sampled to ensure representation across age, sex, socioeconomic status, remoteness, glaucoma severity, clinic settings, and treatment histories. Transcripts were iteratively analyzed to identify key themes pertaining to perceptions of glaucoma surgery and involvement in decision-making. MAIN OUTCOME MEASURES:Surgical perception and involvement themes, including barriers and bridges to confidence in glaucoma surgery. RESULTS:Six key themes were identified: (1) patients feeling rushed; (2) onus on the patient to seek information; (3) undercurrents of anxiety; (4) perceptions of surgery shaped by understanding and expectations of the disease and its treatment paradigm; (5) trust in surgeon imbuing confidence in surgery; and (6) empowerment through understanding of alternatives. Key barriers to patient involvement included patient anxiety, time pressures (real or perceived), and perceived urgency of intervention. CONCLUSIONS:Shared decision-making in glaucoma surgery remains aspirational. This study provides valuable insights into patient perceptions of glaucoma surgery, which can help inform patient-centered care. Readily applicable "practice points" are proposed to optimize patient involvement and empowerment.

PRECIS:Online Circular Contrast Perimetry (OCCP) offers clinically validated threshold perimetry to patients via a web application from their own devices. This study evaluates the feasibility, repeatability, and reliability of OCCP when performed in unsupervised home environments. PURPOSE:To evaluate the feasibility, repeatability, and reliability of online circular contrast perimetry (OCCP) when performed in unsupervised home environments on personal devices. PATIENTS AND METHODS:A total of 55 participants (20 control and 35 open angle glaucoma patients) were recruited. Participants underwent baseline visual field testing using OCCP in a clinical setting, followed by weekly unsupervised home tests over 6 weeks on their personal computers. An online survey was completed afterwards. Global perimetric indices and reliability indices were compared between clinic-based and home-based tests and analyzed to assess the repeatability and reliability of OCCP at home. Rasch analysis assessed the psychometric properties of the survey and intergroup variability. RESULTS:No statistically significant differences were found in mean deviation (MD), pattern standard deviation (PSD), or visual index values between home and clinic tests ( P >0.05), and these values did not significantly alter over the 6 weekly at-home tests. OCCP false positive and fixation loss responses were statistically higher at home compared with baseline ( P =0.002 and P =0.001). Test-retest intraclass correlation coefficients for OCCP home use compared with in-clinic for MD ranged from 0.90 to 0.93, and for PSD ranged from 0.81 to 0.85. Bland-Altman analysis for MD revealed zero test-retest bias with limits of agreement ranging from ±5.28 to ±5.83 dB across the 6 weeks. The survey indicated high user satisfaction; however, Rasch analysis revealed suboptimal precision and targeting. CONCLUSIONS:OCCP retains a similar diagnostic accuracy and repeatability in home environments on personal devices compared with clinic-based environments and has the potential to be utilized as a remote tool for glaucoma screening and surveillance.

PRÉCIS:Online circular contrast perimetry provides visual field assessment on any computer or tablet with no extra hardware. It has good test repeatability and reliability that is comparable with standard automated perimetry. It holds promise for use in disease screening and surveillance to expand the provision of glaucoma care. PURPOSE:To evaluate the repeatability of online circular contrast perimetry (OCCP) compared to standard automated perimetry (SAP) in normal participants and patients with stable glaucoma over 18 weeks. METHODS:Thirty-six participants (13 normal controls and 23 patients with open angle glaucoma) were recruited. OCCP and SAP perimetry tests were performed twice at baseline, then at 6, 12, and 18 weeks. Global perimetric indices were compared between perimetry types and analyzed for short-term and intermediate-term repeatability. RESULTS:There were no statistically significant changes over time for both OCCP and SAP across all groups for mean deviation (MD), pattern standard deviation, and visual index/visual field index ( P >0.05). Test-retest intraclass correlation coefficients (ICCs) for OCCP MD were excellent at baseline (0.98, 95% CI: 0.89-0.99) and good at 18 weeks (0.88, 95% CI: 0.51-0.98). SAP test-retest ICCs were excellent at baseline (0.94, 95% CI: 0.70-0.99) and 18 weeks (0.97, 95% CI: 0.84-0.99). Inter-test ICCs were good, ranging from 0.84 to 0.87. OCCP testing time was shorter than SAP (5:29 ± 1:24 vs. 6:00 ± 1:05, P <0.001). OCCP had similar false-positive (3.84 ± 3.32 vs. 3.66 ± 4.53, P =0.48) but lower false-negative (0.73 ± 1.52 vs. 4.48 ± 5.00, P <0.001) and fixation loss responses (0.91 ± 1.32 vs. 2.02 ± 2.17, P <0.001). CONCLUSIONS:OCCP allows visual field assessment on any computer screen with no additional hardware. It demonstrated good repeatability and reliability with similar performance indices to SAP in both the short term and intermediate term. OCCP has the potential to be utilized as a glaucoma screening and surveillance tool for in-clinic and at-home testing, expanding the provision of care.

Purpose:Online circular contrast perimetry provides visual field testing on any computer or tablet without additional hardware. This study compared outcomes of online circular contrast perimetry (OCCP) and standard automated perimetry (SAP) in a developing world setting. Methods:The longitudinal and observation study was conducted on patients sampled during 2023 at Hanoi Medical University Hospital. Participants were either healthy volunteers as controls or stable glaucoma patients with either primary angle closure or primary open-angle glaucoma. They underwent a comprehensive ocular examination, retinal nerve fiber layer optical coherence tomography scan, and visual field tests performed at baseline and after 3 months and 6 months, using OCCP and SAP in clinic. Results:The current study was carried out in 168 eyes of 87 patients at baseline, 133 eyes of 69 patients at 3 months, and 121 eyes of 63 patients at 6 months. At baseline, OCCP mean deviation (MD) (R2 = 0.804, p < 0.001) and visual index (VI) (R2 = 0.892, p < 0.001) were strongly correlated with SAP MD and visual field index (VFI) respectively. There was strong agreement and correlation between MD and VI/VFI for SAP and OCCP on repeated testing after 6 months. At 6 months AUC of SAP VFI (0.79) was superior to AUC of OCCP VI (0.67, p = 0.036); otherwise there was no difference in AUC of MD or VI/VFI at baseline, 3 and 6 months, when comparing OCCP and SAP. Conclusion:OCCP parameters are significantly correlated with those of SAP. OCCP has the potential to provide a complementary role to SAP in glaucoma screening and monitoring.

Purpose: To establish a normative database using a central 10-degree grid pattern for the online circular contrast perimetry (OCCP) application. Participants: Fifty participants with mean age 65 +/- 13 years were selected for this study. One eye from each participant that met inclusion criteria was randomly included in the cohort. Methods: The web-application delivered online 52-loci perimetry in a central 10-degree pattern using circular flickering targets. These targets consist of concentric sinusoidal alternating contrast rings. Users were guided by the application to the correct viewing distance and head position using in-built blind spot localization and webcam monitoring. A spinning golden star was used as the fixation target and patients performed the test in a darkened room following standard automated perimetry (SAP). Results: The reliability rates and global indices for OCCP were similar to SAP. OCCP mean sensitivity reduced with age at a similar rate to SAP. Mean sensitivity per loci of 10-degree OCCP was greater than SAP by 1.24 log units (95% CI 1.23 to 1.26) and obeyed a physiological hill of vision. Small differences existed in mean sensitivities between OCCP and SAP which increased with increasing spot eccentricity. Mean deviation (MD) displayed good agreement between the two tests. Conclusion: Central 10-degree online circular contrast perimetry via a computer-based application has comparable perimetric results to standard automated perimetry in a normal cohort.

Purpose:The aim was to validate and compare the diagnostic accuracy of a novel 24-degree, 52-loci online circular contrast perimetry (OCCP) application to standard automated perimetry (SAP). Design:Prospective cohort study. Methods:Two hundred and twenty participants (125 normal controls, 95 open angle glaucoma patients) were included. Agreement, correlation, sensitivity, specificity, and area under receiver operating curves (AUC) were compared for parameters of OCCP, SAP, and optical coherence tomography (OCT) for the retinal nerve fiber layer and macular ganglion cell complex inner plexiform layer. Results:Pointwise sensitivity for OCCP was greater than SAP by 1.02 log units (95% CI: 0.95-1.08); 95% limits of agreement 0.860 to 1.17. Correlation and agreement for global indices and regional zones between OCCP and SAP were strong. OCCP mean deviation (MD) AUC was 0.885 +/- 0.08, similar to other instruments' parameters with the highest AUC: SAP MD (0.851 +/- 0.08), OCT retinal nerve fiber layer inferior thickness (0.908 +/- 0.07), OCT ganglion cell complex inner plexiform layer inferior thickness (0.849 +/- 0.08), P>0.05. At best cutoff, OCCP MD sensitivity/specificity were comparable to SAP MD (90/74 vs 94/65%). Conclusions:OCCP demonstrates similar perimetric sensitivities to SAP and similar AUC to SAP and OCT in distinguishing glaucoma patients from controls. OCCP holds promise as a glaucoma surveillance and screening tool, with the potential to be utilized for in-clinic and at-home perimetry and expand community testing.

Purpose: Accurate diagnosis of macular atrophy is paramount to enable appropriate treatment when novel treatments for geographic atrophy and macular dystrophies become available. Genetic testing is useful in distinguishing between the two conditions but is not feasible for the majority of patients in real-world clinical practice. Therefore, we aimed to investigate the potential misdiagnosis of inherited macular dystrophy as age-related macular degeneration (AMD) in real-world ophthalmic practice to assist in the development of guidelines to improve diagnostic accuracy while minimizing genetic testing for targeted patients. Methods: Retrospective review of the medical records of patients diagnosed with AMD, which included imaging, between 1995 and 2023 from a large multidisciplinary private ophthalmic practice in Australia. We will use a stepwise method to screen for probable cases of macular dystrophy, followed by a consensus review by an expert panel. The outcomes are (1) to determine the potential misdiagnosis rate of macular dystrophy as atrophic AMD by retinal specialists and general ophthalmologists; (2) to identify clinical imaging modalities that are most useful for differentiating macular dystrophy from atrophic AMD; and (3) to establish preliminary guidance for clinicians to improve the diagnosis of macular atrophy from AMD in practice, and thereby target cost-efficient genetic testing. Discussion: Improving the diagnostic accuracy of both AMD and macular dystrophy, while ensuring cost-efficient genetic testing, will improve the targeted treatment of macular diseases when emerging treatments become available.

Background: Glaucoma is a group of chronic diseases that cause progressive damage to the optic nerve, resulting in irreversible and potentially debilitating visual loss. A unified, comprehensive and quantitative decision-making methodology is necessary to support clinicians and patients when conducting effective computer-aided glaucoma clinical diagnosis, monitoring, treatment and quality of life (QoL) assessment. Methods: We set out the functional requirements for a patient-centric computerized glaucoma treatment and care ecosystem with a 5- to 20-year time horizon. We evaluate three approaches used for glaucoma diagnosis, treatment and establishment of QoL targets: firstly, the Biomedical Model based on biophysical testing; secondly, conventional QoL assessment approach based on various patient-reported outcome (PRO) questionnaires; and thirdly, Outcomes models to evaluate healthcare based on analysis of Quality Adjusted Life Years (QALYs). Results: We identify many critical issues related to handling and analysis of glaucoma patient health data (technical, regulatory, security and privacy), as well as those related to the assessment of biological, psychological, and socioeconomic wellbeing, risk management, the ability to live independently, with adaptation to different cultures, languages and local healthcare delivery patterns. We address health planners, glaucoma research bodies and healthtech investors. We propose a blueprint for computerized actions required to improve treatment outcomes and to reduce costs while simultaneously providing individualized support to millions of glaucoma patients globally. Conclusions: Such patient-centric methodology must be based on interdisciplinary integration and mutual assistance from these three complementary approaches, as well as on their ongoing simultaneous improvements. To implement an effective healthcare decision support platform globally, all these challenges must be resolved. All this can be achieved in a consistent, cost-effective, high-quality manner.

Purpose To establish a normative database and optimise parameters for personal-computer based perimetry via a web-application using circular contrast targets. Methods Online 24-degree 52-loci perimetry was delivered through a web-application using circular flickering contrast targets. Embedding contrast differentials within targets allows calculation of relative decibel (rdB) per 256-bit greyscale level differential. Target light-band maximum brightness colour was fixed, while the dark-band varied to achieve the desired rdB level. A staircase system was used with two reversals ranging from 0 to 36 rdB levels. Blind spot localisation at the start of the test was used to optimise viewing distance and subsequently count fixation losses. Gaze was maintained on a spinning golden star which moves mid-test to maximise sampling area. Patients performed the test to each eye separately using a computer in a darkened room at 40–45 cm. Results 158 eyes of 101 patients completed the Online Circular Contrast Perimetry (OCCP) test. Mean age was 62.9 ± 14.3 years old. Mean sensitivity reduced with age, at 1.0 relative decibel per decade. Mean sensitivity per locus correlated with standard automated perimetry (SAP) in a physiological hill of vision, with an average difference of 4.02 decibels (95% confidence interval (CI) = 3.77–4.27, p < 0.001) and good agreement between tests. Conclusions Online circular contract perimetry provides accurate perimetric testing with comparable results to standard automated perimetry.

Purpose: To evaluate 3-year safety and efficacy of two second-generation trabecular micro-bypass stents. (iStent inject (R)) with phacoemulsification. Materials and Methods: This multicenter retrospective study of iStent inject implantation with phacoemulsification included data from eight surgeons across Australia. Eyes with cataract and mild to advanced glaucoma [predominantly primary open-angle (POAG), primary angle closure (PAC), or normal-tension (NTG) glaucoma] or ocular hypertension (OHT) were included. Study assessments included intraocular pressure (IOP); number of ocular hypotensive medications; proportions of eyes with 0, 1, 2, or >= 3 IOP-lowering medications; IOP <= 15 mmHg or <= 18 mmHg; visual fields (VF); retinal nerve fiber layer thickness (RNFL); central corneal thickness (CCT); intraoperative complications; adverse events; and secondary surgeries. Results: A total of 273 eyes underwent surgery and had 36-month follow-up. At 36 months versus preoperative, mean IOP decreased by 15.5% (16.4 +/- 4.6 mmHg to 13.9 +/- 3.5 mmHg; p < 0.001), and 70.3% of eyes achieved IOP of <= 15 mmHg (versus 49.1% preoperatively; p < 0.001). The mean medication burden decreased by 68.5% (from 1.51 +/- 1.17 to 0.48 +/- 0.89 medications; p < 0.001); 71.4% of eyes were medication-free (versus 21.6% preoperatively; p < 0.001), while 6.2% of eyes were on > 3 medications (versus 22.3% preoperatively; p < 0.001); 96.3% of eyes maintained or reduced medications vs preoperative. Significant IOP and medication reductions occurred across glaucoma subtypes (POAG, PAC, NTG, OHT): 13-22% for IOP (p < 0.05 for all) and 42-94% for medication (p < 0.05 for all). Favorable safety included few adverse events; stable VF, RNFL, and CCT; and filtering surgery in only 8 eyes (2.9%) over 3 years. Conclusion: In this multicenter cohort from 8 surgeons across Australia, significant IOP and medication reductions were sustained through 3 years after iStent inject implantation with phacoemulsification. Results were favorable across different glaucoma subtypes (including POAG, PAC, NTG, OHT), severities, and surgeons, thereby underscoring the real-world relevance and efficacy of iStent inject implantation for glaucoma treatment.

Purpose: To evaluate the psychometric properties of glaucoma-specific quality of life (QoL) item banks (GlauCAT) and assess their performance using computerized adaptive testing (CAT) simulations. Methods: In this cross-sectional study, 293 participants with glaucoma (mean age ± SD, 70.7 ± 13.2 years; 45% female) answered 342 items in 12 QoL item banks (IBs): Activity Limitation (AL); Driving (DV); Convenience (CV); Economic (EC); Emotional (EM); General Symptoms (GS); Health Concerns (HC); Lighting (LT); Mobility (MB); Ocular Surface Symptoms (OS); Social (SC); and Visual Symptoms (VS). These IBs were assessed using Rasch analysis, and CAT simulations with 1000 simulated respondents were utilized to determine the average number of items to be administered to achieve moderate and high precision levels. Results: The AL, DV, EM, HC, LT, MB, EC, OS, SC, and VS IBs required relatively minor amendments to achieve satisfactory psychometric fit. To resolve multidimensionality, we split CV into Treatment Convenience (TCV) and General Convenience (GCV). Due to poor measurement precision, the GS IB was not pursued further. This resulted in 12 total IBs. In CAT simulations, an average of 3.7 and 7.3 items per IB were required to attain measurement at moderate and high precision, respectively. Conclusions: Following rigorous psychometric assessment, we developed 12 valid glaucoma-specific QoL domains that can obtain highly precise person measure estimates using a small number of items. Translational Relevance: GlauCAT will enable researchers and clinicians to quickly and comprehensively assess the impact of glaucoma and its associated interventions across a range of QoL domains.

Purpose: The purpose of the study was to compare a novel, 24 & DEG;, 52-locus online circular contrast perimetry (OCCP) application against standard automated perimetry (SAP) in terms of both diagnostic accuracy and patient attitudes.Design: This was a cross-sectional study.Subjects: Ninety-five participants (42 controls and 53 open-angle glaucoma patients) were included.Methods: Participants performed both perimetry tests and then completed an online survey. Subjective feedback responses were collected.Main Outcome Measures: Agreement, sensitivity, specificity, and area under receiver operating curves (AUCs) were compared for the parameters of OCCP, SAP, and OCT for the retinal nerve fiber layer (RNFL) and macular ganglion cell complex inner plexiform layer (GCC + IPL). Participant attitudes toward the OCCP test versus the SAP test, in both glaucoma patients and controls, were compared. Rasch analysis assessed the psychometric properties of the survey and intergroup variability.Results: The AUC for OCCP mean deviation (MD) was 0.959 & PLUSMN; 0.02. Compared with other instruments' parameters with the highest AUC, it was superior to SAP MD (0.871 & PLUSMN; 0.04, P = 0.03) and OCT GCC + IPL (0.871 & PLUSMN; 0.04, P = 0.03) and similar to OCT RNFL inferior thickness (IT) (0.917 & PLUSMN; 0.03, no significance). Online circular contrast perimetry pointwise sensitivity was less than SAP by 4.30 dB (95% confidence interval = 4.02-4.59); 95% limits of agreement ranged from-6.28 to-2.33 dB. At the best cutoff, the OCCP MD had a sensitivity of 98% and specificity of 85% for detecting glaucoma. Cohen's kappa demonstrated good agreement with SAP MD (0.69) and OCT RNFL IT (0.62) and moderate agreement with OCT GCC + IPL IT (0.57). Participants preferred OCCP across most survey parameters (P < 0.0001). Rasch analysis demonstrated no differential item functioning for clinical group, gender, or age.Conclusions: With similar diagnostic metrics to SAP, OCCP offers an improved user experience with the potential to increase the provision of care and improve disease surveillance outcomes.

ObjectiveTo describe the development and implementation of a web-based high-quality data collection tool to track the outcomes of glaucoma treatments in routine practice.Methods and analysisThis is a prospective observational registry study. An international steering committee undertook an iterative structured process to define a minimum, patient-centred data set designed to track outcomes of glaucoma treatment. The outcomes were coded into a web-based programme allowing easy access for rapid data entry. Clinicians receive personal reports enabling instant audit of their outcomes. Analyses of aggregated anonymised data on real-world outcomes are analysed and periodically reported with the goal of improving patient care.ResultsThe minimum data set developed by the international steering committee includes the following: a baseline visit captures 13 mandatory fields in order to accurately phenotype each patient’s subtype of glaucoma and to allow comparison between services, and a follow-up visit includes only four mandatory fields to allow completion within 30 s.Currently, there are 157 surgeons in 158 ophthalmology practices across Australia and New Zealand who are registered. These surgeons are tracking 5570 eyes of 3001 patients and have recorded 67 074 visits. The median number of eyes per surgeon is 22 eyes with a range of 1–575. The most common glaucoma procedure, excluding cataract surgery, is iStent inject, with 2316 cases.ConclusionThis software tool effectively facilitates data collection on safety and efficacy outcomes of treatments for different subgroups of glaucoma within a real-world setting. It provides a template to evaluate new treatments as they are introduced into practice.
