Area of Science:

  • Biomedical engineering
  • Computer vision
  • Ophthalmology

Background:

  • Age-related maculopathy (ARM) and retinitis pigmentosa (RP) cause vision loss due to retinal field defects.
  • Current low-vision aids like eccentric viewing have limitations.
  • Electronic image remapping technology offers a novel approach.

Purpose of the Study:

  • To investigate the potential of NASA's Programmable Remapper as a low-vision aid.
  • To explore image redistribution for patients with retinal field defects.
  • To demonstrate the feasibility of using remapping for vision restoration.

Main Methods:

  • Utilized an electronic image remapper to transform image coordinate systems.
  • Investigated radial-only remapping for static image demonstration.
  • Conceptualized a spectacle-mounted display integrating camera input and the remapper.

Main Results:

  • The Programmable Remapper can redistribute lost image information onto functioning retinal areas.
  • Remapping utilizes a larger retinal area, potentially improving acuity compared to eccentric viewing.
  • Static images demonstrated the radial-only remapping process.

Conclusions:

  • The Programmable Remapper shows promise as a low-vision aid for conditions like ARM and RP.
  • Further development could lead to a cost-effective, portable low-vision prosthesis.
  • Training and feedback may optimize patient use of the remapping aid.
