Some researchers think that people with work disability due to ARMD seeking vocational rehabilitation (VR) services who are exposed to an "agency access intervention" are more likely to gain entrance to the VR system and be determined eligible for services than are similar people not exposed to the intervention. Further, they think that people with work disability due to ARMD who are determined to be eligible for VR services, and who are exposed to an "agency enhancement intervention" while receiving services, are more likely to become and remain employed upon completion of the VR program than are similar people not exposed to the intervention.
