Trial Outcomes & Findings for Visuomotor Rehabilitation Training for Manual Task Deficits From Macular Scotomas (NCT NCT01691027)

NCT ID: NCT01691027

Last Updated: 2018-02-23

Results Overview

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

Participant Flow

Subjects with bilateral AMD, no foveal vision, and acuities poorer than 20/60 in each eye were screened in the eye clinic and those who met inclusion criteria were enrolled in the study. On each laboratory visit, subjects' eyes were checked for angle closure and, if angles wee open, dilated the eye to be tested

Enrolled subjects when found to have residual foveal vision in baseline SLO retinal functional map and/or are unable to follow the instructions for SLO testing were excluded from the study before training assignment.

Baseline Characteristics

Only 4 subjects with ages in range of 65 to 92 participated and were able to complete all training.

Baseline characteristics by cohort

Baseline characteristics by cohort
Measure
Crossover Design. All Subjects Undergo All Treatments.
n=4 Participants
Each participating subject will have three training modules on a tablet computer: scotoma awareness, line and curve tracing, and video games. The order of modules will be different for different groups of subjects. Training on a module will cease when the subject reaches a performance criterion. Retinal assessments will occur after each training module completion.

PRIMARY outcome

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

Population: Out of Ten selected subjects, 3 were rejected after completing Baseline SLO retinal function map because of residual foveal vision. Two subjects failed to follow the instructions for SLO testing. One subject completed initial phase but failed to complete testing because of medical problems. Four subjects were able to complete all testing.

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

Measure
Visuo-motor Training
n=4 Participants
Participants undergo training on three modules, (1)scotoma awareness, (2) line and curve tracing, and (3) video games. SLO assessments of changes in fine manual task performance was measured by an improvement in mean maze tracing and printing score. Improvement in visuo-motor control was measured by stylus ellipse area and stylus-PRL distance before and after training.

SECONDARY outcome

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

Population: Out of Ten selected subjects, 3 were rejected after completing Baseline SLO retinal function map because of residual foveal vision. Two subjects failed to follow the instructions for SLO testing. One subject completed initial phase but failed to complete testing because of medical problems. Four subjects were able to complete all testing.
