Persistence of Glaucoma Patients With Web-Browser-Based Visual Field Test

The purpose of this prospective study is to assess patient persistence and adherence with a 6-month period of at-home visual field testing using an iPad with a novel web-browser-based visual field test, the EyeSimplify platform (M\&S Technologies, Niles, IL). Use of this test is intended to supplement, but not replace, regular clinic visits. The proposed study will be conducted at the University of Iowa Hospitals and Clinics. We estimate 50 subjects will be recruited to participate in the study. Data collected will not include patient identifiers, but will instead be coded. The research will involve prospective collection of visual field tests. Patients with suspected, mild, moderate, or severe glaucoma will be included. Clinical data including age, gender, ethnicity, visual acuity, intraocular pressure, severity of disease, past and comparative Humphrey HFA-III visual field test performance, EyeSimplify visual field test performance, and EyeSimplify usability survey will be recorded. Following study recruitment, subjects will be asked to take EyeSimplify visual field tests at home biweekly for six months. They will have no additional responsibilities between tests. Subjects will access the EyeSimplify web browser on an iPad provided by the research team, using a link and login credentials provided to them by a research assistant. Upon logging into the EyeSimplify web browser, subjects will click the "Start Test" button found along the left side of the window and follow the prompts presented on screen to calibrate their screen. Screen calibration involves holding a driver's license/credit card/ID to the screen to ensure the test window is the appropriate dimensions. Following screen calibration, subjects will follow the test prompts presented on screen to complete their visual field test. Test results are automatically sent to the research assistant who issued the exam, so subjects may exit the browser after each test. Upon study completion, subjects will be asked to fill out a brief user experience survey. M\&S Technologies is the developer of the EyeSimplify visual field test platform. As the developers, M\&S Technologies maintains a secure, encrypted, HIPAA-compliant database of test participants. This database includes patient profiles containing unique subject IDs (de-identified), birth year (but not specific date), and visual field testing results. Outside of this testing information, M\&S Technologies does not have access to any additional patient information.
