Purpose
This randomized, controlled clinical trial, the Low Vision Depression Prevention TriAL (VITAL), will test the efficacy of collaborative low vision rehabilitation (LVR) to prevent depressive disorders in Age-Related Macular Degeneration (AMD). In this innovative intervention, a low vision occupational therapist collaborates with a low vision optometrist to develop and implement a care plan based on a subject's vision status, rehabilitation potential, and personal rehabilitation goals. An independent rater masked to treatment assignment will assess depressive disorders meeting DSM-IV criteria (primary outcome) and targeted vision function and vision-related quality of life (secondary outcomes) at baseline and then at 4 months to evaluate short-term effects (main trial end point) and at 12 months to evaluate long-term effects.

BA-LVR: Experimental
In BA-LVR, a low vision occupational therapist (OT) will deliver Behavior Activation (BA), a psychological treatment to prevent depression. This will be administered in the context of the standard of low vision care for OTs as defined by the American Occupational Therapy Association (AOTA). The OTs will collaborate with low vision optometrists, who will deliver the standard of low vision care as defined by the American Optometric Association. The optometrists will evaluate remaining vision and magnification needs, prescribe optical devices, and provide the OTs with initial care plans. The OTs will subsequently meet with subjects in their homes 6 times over 12 weeks to enhance device use, home modifications, and compensatory strategies.

Behavioral: BA-LVR
Low vision clinic-based optometry plus 6 in-home occupational therapy visits

ST-LVR: Placebo Comparator
Subjects randomized to ST-LVR will receive clinic-based low vision optometry, in addition to 6 in-home Supportive Therapy (ST) sessions. ST is a placebo condition that controls for the attention that subjects in the active treatment arm will receive.

Age-related macular degeneration (AMD) is the leading cause of blindness in older persons in the U.S. and affects more than 10 million people. One third of patients with AMD become clinically depressed when they lose the ability to pursue valued activities. Because their depression is disabling and unlikely to be treated, preventing depression in AMD is a public health imperative as the population ages.
We will recruit 200 subjects who have bilateral AMD and subthreshold depressive symptoms. Their bilateral vision loss and subthreshold depressive symptoms increase their risk to develop more severe depressive disorders and functional decline. We will randomize eligible subjects to collaborative Low Vision Rehabilitation (LVR) (optometrist and home-based OT) or enhanced LVR (optometrist and home-based Supportive Therapy). In this study, usual care LVR is enhanced with Supportive Therapy (ST), which is a standardized placebo psychological treatment that controls for attention.
Many older persons with AMD understandably become depressed when their vision loss prevents them from pursuing valued goals. This necessitates a disease management strategy that combines treatment for vision loss and depression. Because depression in AMD is rarely treated, preventing depression is more sensible than waiting to treat it after diagnosis or failing to treat it at all. As the population ages and more people are affected with AMD, finding ways to prevent depression and improve daily functioning has great public health importance. For these reasons, the VITAL Trial has high clinical significance to patients with AMD, and wider public health significance as our society confronts the challenge of caring for the growing population of older adults with chronic disabilities.
