The aim of the research project is to validate the use of a novel functional assessment tool designed to document how participants with a vision impairment complete activities of daily living in a real world environment.
There is currently no multisensory tool to assess functional vision in people with a vision impairment. This study is designed to capture and assess the reliability and validity of a novel tool developed by multi-disciplinary experts in ophthalmology, optometry, orthoptics, orientation and mobility (O\&M) specialists, and people with lived experience of low vision. The tool is designed to be used in both clinical and in interventional clinical trial setting, to provide functional vision assessment measures within real-world outcomes. The development of this tool is at a critical junction in time where a range, of interventions are being developed for people with low vision including bionic eyes, and gene and cell therapies. The FDA requires trials to show real world functional outcomes in addition to traditional endpoints, hence a tool like the ATOMM may have wide use and implications. This study will recruit participants with varying levels of vision impairment to assess the reliability of the ATOMM.

Evaluating validity and reliability
Two investigators will attend the local environments of each participant for repeated sessions at least two weeks apart to conduct functional assessments using the ATOMM. The tool contains 3 domains involving 15 pre-determined tasks, each designed to encompass common activities of daily living. An example includes independently navigating around the home. A maximum score of 30 points/domain is achievable on a 7 point Likert scale. The investigators will use intraclass correlation coefficients (ICC) to quantify the interrater agreement between two assessors and test-retest reliability over the three domains across the two sessions.
Time frame: From enrolment to assessment could range from 2 to 4 weeks.
