N/A

Recruiting

Led By Stephen Engel, Ph.D.

Research Sponsored by University of Minnesota

Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Stable fixation (+/- 1 deg) using their PRL.

16 years or older

Must not have

Central vision loss of less than 5 deg diameter; scotomas that do not cover the fovea; unilateral scotomas

Timeline

Screening 3 weeks

Treatment Varies

Follow Up measured during fifth visit; each visit is one day only and this measure refers to data gathered during a < 1 hr long reading session during that day

Awards & highlights

No Placebo-Only Group

Summary

This trial will test how well people with central vision loss can read with and without different kinds of remapping of missing text to different parts of the visual field, compared to people with no vision loss.

Who is the study for?

This trial is for individuals aged 16 or older with central vision loss from age-related macular degeneration. Participants must have a stable gaze within one degree using their preferred retinal locus (PRL) and be able to calibrate an eye tracker. Those with cognitive impairment, poor fixation, or insufficient central vision loss are excluded.

What is being tested?

The study measures reading performance in patients with Central Vision Loss. It compares the effectiveness of traditional remapping versus personalized remapping of text to different visual fields in aiding reading.

What are the potential side effects?

Since this trial involves non-invasive techniques like eye tracking and visual tests rather than drugs or surgery, there are no direct side effects associated with the interventions being tested.
