Closed Vision Rehabilitation Research Trials

Implantable Miniaturized Telescope
PI: Susan A. Primo, OD, MPH
Coordinator: Jayne Brown, COMT
Status: Closed.

Summary: Study and evaluation of long-term change in visual acuity and description of patient selection/management pearls for telescope prosthesis patients with macular degeneration.

Inclusion Criteria:
• Previously implanted with the IMT
• Motivated to do extensive occupational therapy

Exclusion Criteria:
• None

Sponsor: VisionCare, Inc.

 

Age-Related Macular Degeneration and Cortical Reorganization
PI: Susan A. Primo, OD, MPH
Coordinator: Jeff Horton, COMT
Status: Closed.

Summary: The impact of the proposed research will be to bridge the knowledge gap between cortical plasticity and visual function. Results from these studies will provide answers for how behavioral improvements in AMD patients lead to changes in underlying brain activity. Once this link is made, clinicians and health care engineers can use this to devise rehabilitation therapies and technologies, to foster efficient cortical reorganization and to maximize the use of residual vision in patients with AMD.

Inclusion Criteria:
• Macular degeneration
• Vision worse than 20/80

Exclusion Criteria:
• Nystagmus
• Previous occupational therapy for fixation training

PI: Susan A. Primo, OD, MPH
Co-Investigators: Kenneth Rosengren, OD and Thao Vu, OD
Coordinator: Jeff Horton, COMT
Status: Closed.

Summary: Study of a new, innovative prism design on mobility and satisfaction in patients with hemianopic field defects.

Inclusion Criteria:
• Complete homonymous hemianopia
• Able to walk independently

Exclusion Criteria:
• Visual neglect
• Cognitive deficits
• Previous history of wearing prisms
