Brief summary
Vision loss is common among older adults and leads to an increased risk for depression and difficulties in daily tasks, thus requiring dependence on caregivers. This study will assess the feasibility of providing two virtual interventions, Sahaj Samadhi Meditation (SSM) and Health Enhancement Program (HEP), to supplement care of patients with irreversible age-related vision loss (IARVL) and their caregivers, with the goal of enhancing mental health and quality of life.
Detailed description
Through a high-quality, single-blind, three-arm mixed-method pilot feasibility study using randomized treatment assignment, the study team will assess two new innovative interventions, Sahaj Samadhi Meditation (SSM) and Health Enhancement Program (HEP), both delivered virtually, to augment clinical care of patients with irreversible age-related vision loss (IARVL), with the goal of enhancing mental health and quality of life (QOL) for patients and/or their caregivers. Participants will be blinded to the treatment hypothesis, while investigators and treating clinicians will be additionally blinded to the intervention. Both SSM and HEP will be taught over 4 consecutive days in similar sized groups (10 patients and/or their 10 caregivers) followed by weekly reinforcement sessions for subsequent 11 weeks. Self-rated questionnaires will be used to collect data on quality of life and mental health symptoms at 0-week and 12-week follow-up
Interventions
BEHAVIORALSahaj Samadhi Meditation
Sahaj Samadhi Meditation (SSM) is a form of automatic self-transcending meditation that involves relaxed attention to a precise sound (mantra), to allow stress reduction and deep relaxation. This technique is easy to learn and offers the support of a group and facilitator.
BEHAVIORALHealth Enhancement Program
The Health Enhancement Program (HEP) is a standardized program used to teach participants about health promotion, including the benefits of a lifestyle of healthy diet, music, recreation, and exercise. In HEP, participants get the support of a group and facilitator, and talk through and try to implement positive health-enhancing life changes.

Intervention model description
Patients will undergo 1:1:1 randomization to Sahaj Samadhi Meditation or Health Enhancement Program or Treatment as Usual, stratified by gender. Twenty-five irreversible age-related vision loss patients and their 25 caregivers will be assigned, on a rolling basis, in the three groups.
