Area of Science:

  • Neuroscience
  • Ophthalmology
  • Rehabilitation Medicine

Background:

  • Hemianopia, a visual field defect, significantly impacts daily functioning and quality of life.
  • Traditional rehabilitation approaches for hemianopia often rely on computer-based training.
  • There is a need for effective, noncomputerized training programs that simulate real-world activities.

Purpose of the Study:

  • To evaluate the efficacy of a noncomputerized multitasking compensatory saccadic training program (MCSTP) for hemianopia patients.
  • To assess improvements in visual ability, quality of life (QL), and functional independence (FI) using 3D real-world objects.
  • To compare a 3D-MCSTP intervention with a no-training group.

Main Methods:

  • A quasiexperimental, pretest/posttest study design was employed with an intervention group (IG) and a no-training group (NTG).
  • The 3D-MCSTP involved 12 weeks of in-office visits and customized home-based training using real-world objects and everyday visuomotor activities.
  • Participants (n=40) were matched for age, hemianopia type, and brain injury duration.

Main Results:

  • The IG demonstrated significant improvements in visual-processing speed (57.34%) and visual attention/retention ability (26.67%) compared to the NTG (P < 0.0001).
  • The IG showed large effect sizes in 75% of QL and FI dimensions, while the NTG had negligible effect sizes in 96% of these dimensions.
  • All participants completed the study, and groups were comparable at baseline.

Conclusions:

  • The customized 3D-MCSTP effectively improved complex visual processing, quality of life, and functional independence in patients with hemianopia.
  • Combining in-office and home-based training with real-world object simulation enhances neurovisual rehabilitation efficiency.
  • This approach may be superior to computer-screen methods due to better patient motivation and stimulation of visual processing mechanisms.
