Optical Head-Mounted Display Technology for Low Vision Rehabilitation
Retinal Dystrophies, Healthy
About this trial
This is an interventional treatment trial for Retinal Dystrophies
Eligibility Criteria
Inclusion criteria for subjects with retinal dystrophy:
- diagnosis of retinal dystrophy
- severe vision loss that constitutes legal blindness
- able to perform a reliable Goldmann visual field test
- constricted visual field less than or equal to 20 degrees by Goldmann perimetry using the III4e stimulus in at least one eye with best-corrected visual acuity ≥ 20/60
Inclusion criteria for control subjects:
- healthy controls
- visit history with the Comprehensive and Pediatric Ophthalmology Services at the University of Michigan
- able to perform a reliable Goldmann visual field test
Exclusion criteria for subjects with retinal dystrophy:
- movement disorder that precludes evaluation of mobility
- functional vision loss
- pregnant women
Exclusion criteria for control subjects:
- visually significant ocular condition other than correctable refractive error
- movement disorder that precludes evaluation of mobility
- functional vision loss
- pregnant women

Healthy Age-Matched Controls
Subjects with retinal dystrophy will have their visual field, gait and self-reported mobility tested at baseline. Subjects will then be fit with a head-mounted display and undergo a brief training with the investigators to learn about use of the device. After a 2 week period of in-home adaptation to the device, their visual field, gait and self-reported mobility will be retested.
Age-matched control subjects without eye disease will have their visual field, gait and self-reported mobility tested at baseline. Control subjects will then be fit with a head-mounted display and undergo a brief training with the investigators to learn about use of the device. After a 2 week period of in-home adaptation to the device, their visual field, gait and self-reported mobility will be retested.
