Trial Outcomes & Findings for Beacon Sensors and Telerehabilitation for Low Vision (NCT NCT04066075)

Last Updated: 2025-06-29

Results Overview

change in the 'Activity Inventory' questionnaire; scores for reading ability were Rasch analyzed in logit units with higher or positive scores indicating less difficulty (i.e., improvement)(Higher values represent a better outcome/ability). Range of changes from 1 month to 4 months after receiving a magnification device were -2.06 to 2.59.

Participant Flow

The recruitment period occurred from October 10, 2019 through December 14, 2022 at academic medical or optometric clinical centers or private optometric practices.

Enrolled participants were excluded from the study before randomization assignment to arms or groups if they did not complete the baseline study assessments by phone.

Participant milestones
Measure	Telerehabilitation With Low Vision Provider Remote training for newly prescribed magnification devices via Zoom videoconferencing with the vision rehabilitation provider in-office and the participant at home. The training for magnifiers was individualized based on participants' needs, by providing verbal instructions to adjust placement of the reading material and/or magnifier, including feedback on working distance, viewing angle, movement and/or obtaining appropriate magnification levels and field of view while reading at near.	Usual Care (Active Control) Training provided in-office or clinical settings in-person for the use of newly prescribed magnification devices that was individualized based on participants' needs. The training for magnifiers involves instructions to adjust placement of the reading material and/or magnifier, including feedback on working distance, viewing angle, movement and/or obtaining appropriate magnification levels and field of view while reading at near.
