Brief summary

To understand the difficulties in activities and participation restriction experienced by older adults with different patterns of visual loss. The primary hypothesis is that older adults with different patterns of visual loss will demonstrate differences in performing seven standardized daily activities in the clinic setting. It is also expected that there will be differences in performance and engagement in self-selected activities across people who experience different patterns of visual loss.

Interventions

This is a cross-sectional observational study that involves conducting observational and self-reported assessments related to the activities, participation and goals of a sample of participants recruited from the Tan Tock Seng Hospital (TTSH)’s low vision clinics. The questionnaires and clinical assessments that will be completed by participants are: 1) Abbreviated Mental Test 2) Bells Test 3) Short Physical Performance Battery 4) Box and Block Test 5) Visual acuity screening with Low vision

Session 2 will occur within two weeks of session 1. The assessments and interviews will be conducted by one of the investigators, who is an Occupational Therapist. The broad aim is to understand the difficulties in activities and participation restriction experienced by older adults with different patterns of visual loss and their self-identified goals.
