“…Current perimetry machines often cause patient anxiety, and this has been shown to adversely affect adherence and test performance. 21 Offering patients an improved user experience may serve to promote patient engagement, adherence, and satisfaction. 24 Improved access to care might help increase early detection rates (eg, in younger patients) or allow for more frequent monitoring (eg, in glaucoma patients at high risk of disease progression).…”

“…A reliable, cost-effective, and accessible perimetry test offers several advantages to both patients and providers over conventional machines, with the versatility to be used either supervised in-clinic or for home monitoring. Current perimetry machines often cause patient anxiety, and this has been shown to adversely affect adherence and test performance 21. Offering patients an improved user experience may serve to promote patient engagement, adherence, and satisfaction 24.…”

“…To enhance adherence to surveillance programs, ideally, the test should be both enjoyable and practical. One of the limitations of older perimetry machines is that some patients find them uncomfortable, tiring, and anxiety provoking 21,22. In recent years, clinic-based perimetry has been optimized for improved speed including the development of Swedish Interactive Threshold Algorithm (SITA) Faster, which can offer significantly shorter testing times and the potential for more frequent clinic monitoring 23.…”

“…In recent years, clinic-based perimetry has been optimized for improved speed including the development of Swedish Interactive Threshold Algorithm (SITA) Faster, which can offer significantly shorter testing times and the potential for more frequent clinic monitoring 23. Although a shorter test offers practical benefits, SITA Faster does not improve many of the disadvantages linked to the perimetry machines themselves, namely their expense, the need for technical maintenance and trained operating staff, the inability for home monitoring and for some patients, ergonomic discomfort and anxiety associated with using perimetry machines 21. Ultimately, a digitized test, accessible from any standard computer, which is intuitive, comfortable, and accurate, may offer an improved user experience, promoting both adherence and patient satisfaction.…”

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 To assess the effect of Glaucoma awareness, knowledge, and anxiety on patients under visual field analysis by Humphrey's visual field analyzer (HFA) and optical coherence tomography(OCT) Methods This prospective comparative cohort study included glaucoma patients undergoing HFA (Group A)( n = 150) and OCT(Group B) ( n = 150). Each group consisted of 75 newly diagnosed patients and 75 patients who were on follow-up. Participants completed State trait anxiety inventory form Y2(STAI) before and after the test to assess pre-test and intra-test anxiety. Another validated and structured questionnaire was used to assess patient awareness and knowledge of glaucoma. Anxiety scores were used to make correlations and comparisons between the two groups and also against visual field reliability indices. The impact of awareness on anxiety scores and its correlation with reliability indices were also determined. Results Overall pretest and intratest anxiety scores in patients undergoing HFA were 52.39(9.5) and 52.45(8.6)and OCT 53.04(8.0) and 53.83(8.2) respectively.Pretest anxiety was less in follow-up patients of both groups(Group A-51.04,Group B-52.72).There was no statistically significant difference between the groups(pretest p = 0.52,Intratest p = 0.15). Anxiety score was found to be significantly high in female participants(54.07, p = 0.01)and those without awareness( p < 0.001). Patients with education of graduation and above in group B had significantly lower anxiety scores( p = 0.007). Conclusion Anxiety levels induced by both diagnostic modalities HFA and OCT appear to be similar and it does not affect the reliability indices.Anxiety score was higher in female participants and participants lacking disease awareness.

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.
