Full description

Study Overview The "Next Generation Home Vision Assessment" study aims to evaluate the feasibility and accuracy of conducting vision assessments at home using a web-based platform. This prospective, non-interventional, multi-center study will compare home-based vision tests with traditional hospital-based assessments.

Study Background The COVID-19 pandemic has significantly limited patients' ability to attend in-person eye clinic appointments, impacting vision assessments and management. Ramifications in delays continue to have an impact.

Study Rationale This study seeks to validate home-based vision assessments against standard in-person evaluations to ensure patients can be effectively monitored and managed remotely. The use of a web-based platform for vision tests could offer a reliable alternative, reducing hospital visits and maintaining care standards.

Objectives and Endpoints Primary Objective: To compare the accuracy of home-based visual acuity tests to hospital-based assessments.

Secondary Objectives: To evaluate other aspects of visual function (e.g., visual fields, color vision, contrast sensitivity) and measure patient engagement and test duration.

Study Design Type: Prospective, non-interventional Participants: Adults and children attending hospital eye services Sample Size: 360 completed assessments Duration: Minimum of 6 months

Study Procedure Participants attending hospital eye services will be recruited and provided with a patient information leaflet. Those willing to participate will undergo a visual acuity test +/- additional vision tests (secondary outcomes) during a video consultation. Hospital-based assessment results will be compared to home-based test results to determine accuracy.
