NCT01691027 | Completed Results

• 1 other identifier: C1000-R
• Study Type: interventional
• Target: 4
• Locations: 1 country
• Sites: 1

Brief Summary

The research is aimed at developing and testing a new method of visual-motor rehabilitation of Veterans with macular degeneration by using inexpensive "tablet" computers at home.

Conditions

Scotoma, Central; Central Visual Impairment

Keywords

scotoma, central; visual motor coordination

Outcome Measures

Primary Outcomes (1)

• Improvement in Eye-hand Coordination

  Maze tracing represents the fine eye-hand coordination needed for a wide variety of manual tasks and an improvement in maze tracing indicates an improvement in eye-hand coordination

  base line, pre-test, post tracing and videogames training

Secondary Outcomes (1)

• Stylus to Eclipse Area

  Base line, Pre and Post training (approximately 3 months)

Study Arms (1)

Visuo-motor training for low vision

EXPERIMENTAL

All participants undergo training on scotoma awareness, Line and Circle Tracing and Video games

Behavioral: Visuo-motor training

Interventions

Visuo-motor training BEHAVIORAL

Participants will undergo training on three developed software modules on Samsung Galaxy Note Pro tablets to see their effect on low vision rehabilitation

Also known as: Scotoma Awareness, Line and Circle Tracing, Video games (Pong and PacMan)

Visuo-motor training for low vision
