PURPOSE. To compare the efficacy of behavioral activation (BA) plus low vision rehabilitation with an occupational therapist
(OT-LVR) with supportive therapy (ST) on visual function in patients with age-related macular degeneration (AMD).
METHODS. Single-masked, attention-controlled, randomized clinical trial with AMD patients with subsyndromal depressive
symptoms (n = 188). All subjects had two outpatient low vision rehabilitation optometry visits, then were randomized to in-home
BA + OT-LVR or ST. Behavioral activation is a structured behavioral treatment aiming to inctease adaptive behaviors and achieve
valued goals. Supportive therapy is a nondirective, psychological treatment that provides emotional support and controls for
attention. Functional vision was assessed with the activity inventory (Al) in which participants rate the difficulty level of goals and
corresponding tasks. Participants were assessed at basetine and 4 months.
RESULTS. Improvemcnts in functional vision measures were seen in both the BA + OT-LVR and ST groups at the goal level (d e
0.71; d = 0.56 respectively). At the task level, BA + OT-LVR patients showed more improvement in reading, inside-the-home tasks
and outside-the-home tasks, when compared to ST patients. The greatest effects were scen in the BA + OT-LVR group in subjects
with a visual acuity 220/70 (d = 0.360 reading; d = 0.500 inside the bome; d = 0.468 outside the home).
CONCLUSIONS. Based on the trends of the AI data, we suggest that BA + OT-LVR services, provided by an OT in the patient's
home following conventional low vision optometry services, are more effective than conventional optometric low vision services
alone for those with mild visual impairment.
