Efficacy of Enhancing Low Vision Mobility Thru Visual Training in Virtual World
Completed
Conditions studied: Low Vision
In brief
Low vision patients have difficulty acquiring sufficient visual information in a timely manner for the purpose of performing challenging daily tasks, such as traveling independently and safely through busy streets. The advance of virtual reality techniques has provided a potential platform for training low vision patients to use their remaining vision more efficiently, but the key issue is always whether the patient's visual experiences in a virtual world can be transferred to the real world. The proposed study is designed to provide definite answer to this question.

Who can join
Age: 19 and older, up to 81. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Ambulatory and have independent traveling as one of their rehabilitation goals.
- Participants with central field loss should have best corrected binocular visual acuity between 20/200 and 20/1000, but with relatively intact peripheral visual field (>80o).
- Participants with peripheral visual field loss should have >20/63 visual acuity and no more than 20 deg diameter but not less than 8 deg diameter visual field in the better eye.
You may not qualify if…
- Participants who have a mixture of central and peripheral field loss.
- Previous or current recipient of O\&M training.
- Participants who have plans to receive O\&M training during the study period.
- Age younger than 19 or older than 81.
- Significant cognitive impairment as determined with the Short Portable Mental Status Questionnaire (≥2 errors); inability to understand and speak English.
- Severe hearing impairment that interferes with interactions with O\&M specialists.
- Inability or unwillingness to make visits required by the study.
- Not living in the Birmingham-Jefferson county area.
