About this trial
This study will help develop new methods of rehabilitating Veterans with vision loss due to Age-related macular degeneration.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
The subject is a Veteran.
The subject is 50 years of age.
The subject has best-corrected visual acuity (BCVA) of 20/40 or worse in each eye, as determined by the standard CNVAMC optometric tests.
The subject has visual field deficit of 10O in either eye as determined by the Octopus 900 perimetry (Haag-Streit Diagnostics, Haag-Streit USA, Mason, OH) administered by CNVAMC. (When the deficit/s are binocular, they do not necessarily have to be in binocularly corresponding positions.)
Disqualifiers
According to the patient's VA clinical records, the patient has one or more clinically diagnosed neurological disorder.
According to the patient's VA clinical records, the patient has one or more clinically diagnosed cognitive deficits.
According to the patient's VA clinical records, the patient has been clinically diagnosed with a psychiatric disorder that would make it unduly uncomfortable or otherwise clinically inadvisable for the subject to participate in the study.
According to the patient's VA clinical records, according to the patient, or both, the patient has motor disorder/s that would make it unduly uncomfortable or otherwise clinically inadvisable for the subject to participate in the study.

Treatments tested in this trial
Study-specific rehabilitation (SSR) procedures
BehavioralStudy-specific rehabilitation procedures will systematically manipulated the spatial or temporal synchrony (or coordination) of visual vs. haptic inputs that the subjects receive.
Treatment groups
Trial outcomes
Primary outcomes
Accuracy of object recognition
This outcome will be measured as the accuracy (% correct) with which the study subjects recognize the text objects before, during and after their participation in the study procedures.
Response of brain regions of interest (ROI) as reflected in the BOLD (blood oxygenation level-dependent) response
This outcome will be measured as changes (if any) of the BOLD responses of brain ROIs before, during and after their participation in the study procedures.
