简要总结
The goal of this study is to examine the ability of optical head-mounted display technology to enlarge the visual field of patients with severe visual field loss due to retinal dystrophy and to improve mobility and patient-reported outcomes.
详细描述
Worldwide it is estimated that 191 million people have moderate to severe visual impairment (MSVI) and an additional 32.4 million are blind. Patients with uncorrectable MSVI may undergo low vision rehabilitation (LVR), which has been shown to improve functional abilities, such as mobility. However, existing LVR strategies do not adequately address severe visual field constriction.
In this pilot study, the investigators will test the hypothesis that optical head-mounted display (HMD) technology expands constricted visual fields and improves mobility outcomes for patients with retinal dystrophy. We will use the Moverio HMD platform which is considered a non-significant risk device. Outcomes for patients with retinal dystrophy will be compared to normal age-matched controls.

研究组 & 干预措施
Retinal Dystrophy
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.
干预措施: Head-Mounted Display (Device)
Healthy Age-Matched Controls
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.

结局指标
主要结局
Change in the Planimetric Area of Goldmann Visual Field With the Use of Head-mounted Display Technology Compared to Baseline (Measured in Degrees Squared)
时间窗: Baseline and two to four weeks
Using computer software we will calculate the area of participants' Goldmann visual fields in order to obtain a summary quantitative measurement of the extent of peripheral vision. Average of both eyes visual fields with intervention.
次要结局
- Change in Gait Speed Compared to Baseline (Measured in Seconds)(Baseline and two to four weeks)
