Patient and technician perspectives following the introduction of frontloaded visual field testing in glaucoma assessment
Phu J; Kalloniatis MClinical and Experimental Optometry 2021; 0: 1-7
CLINICAL RELEVANCE: Frontloaded visual field testing (twice per eye per session) is well-tolerated by patients and technicians, representing a viable strategy that can be implemented in routine clinical practice to capture enough clinical perimetry data for effective disease diagnosis, surveillance and management. BACKGROUND: To determine the experiences of patients and technicians following the implementation of frontloaded visual field testing (multiple tests per eye within the same session) in a glaucoma service. METHODS: This was a retrospective, cross-sectional study. A written questionnaire was administered to patients (three questions) attending the glaucoma service at the Centre for Eye Health for glaucoma assessment and to their administering perimetry technicians (two questions). The questionnaire was administered after static automated perimetry (24-2 SITA-Faster on the Humphrey Field Analyzer) was performed twice for each eye (frontloaded) within the same session. Respondents were asked to provide a 1-5 Likert scale response to questions that targeted operational issues for frontloaded visual field testing. Responses were correlated against to demographic (age, gender, ethnicity) and clinical (diagnosis, refractive error, visual field indices, test duration) parameters. RESULTS: Approximately 90% of patient respondents agreed that frontloaded visual field testing was clearly explained to them, that they were comfortable during the test, and would prefer completing the tests at a single visit rather than returning to repeat the test. Most technician respondents were also able to keep their patients comfortable. 13% of technician respondents felt they ran late during the session, but on average, the total test duration for four visual field tests was 13 minutes, including breaks. There was no correlation found between demographic and clinical factors, and the responses. CONCLUSIONS: Frontloaded visual field testing was well-tolerated by patients and technicians. Strategies that may be helpful for other clinics to adopt this new paradigm are described.
