NCT06651736

Brief Summary

The purpose of this study is to understand if combining Low Vision Rehabilitation (LVR) with Emotional Regulation Therapy (ERT) can help people with inherited retinal diseases (IRDs) that experience emotional distress related to participants' vision loss. The study team hypothesize that treatment with LVR will produce measurable functional gains and that these effects will be enhanced by ERT-linked improvement among the subgroup of IRD patients with elevated vision-related anxiety.

Outcome Measures

Primary Outcomes (6)

  • Determine if LVR improves vision-related disabilities and distress measures by the Michigan Vision-related Anxiety Questionnaire (MVAQ)

    The Michigan Vision-related Anxiety Questionnaire is a 14 -item questionnaire designed to assess anxiety/distress related to vision impairments. Responses can range between: Never, Sometimes, Frequently, Always, N/A for Non-Vision Reasons. The questionnaire provides 2 scores (one for anxiety about rod function and one for anxiety about cone function). Both of those scores fall between -3 and 3 (an increasing score indicates higher levels of anxiety).

    Baseline to 6 month

  • Determine if LVR improves vision-related disabilities and distress measures by the Michigan Retinal Degeneration Questionnaire (MRDQ)

    The Michigan Retinal Degeneration Questionnaire is a 59-item questionnaire aimed to assess vision-related functional impairment. Responses can range between: None, A little difficulty, Moderate difficulty, Extreme difficulty, My vision is too poor to do this, N/A for non-vision reasons. The questionnaire provides 7 scores (for 7 different domains of vision) and also range from -3 to 3 (0 is centered at the mean trait level of the population and extreme values for theta (i.e., -3, +3) are indicative of low or high visual dysfunction based on item responses).

    Baseline to 6 month

  • Determine if LVR measures are different between low-distress and high-distress groups accessed at month-6 by MVAQ

    Comparison between low-distress arm and high-distress arm prior to ERT treatment at month-6. The Michigan Vision-related Anxiety Questionnaire is a 14 -item questionnaire designed to assess anxiety/distress related to vision impairments.

  • Determine if adjunctive ERT treatment in the high-distress arms improves vision-related disabilities and vision-related distress measures greater than LVR alone measured by MVAQ

    The Michigan Vision-related Anxiety Questionnaire is a 14 -item questionnaire designed to assess anxiety/distress related to vision impairments. Responses can range between: Never, Sometimes, Frequently, Always, N/A for Non-Vision Reasons. The questionnaire provides 2 scores (one for anxiety about rod function and one for anxiety about cone function).

Study Arms (3)

Arm 1 - Low Vision Rehabilitation LVR

ACTIVE COMPARATOR

Participants (N \~ 60) without vision-related anxiety will be designated to Arm 1 and receive LVR. This group is intended to be a comparison for the higher vision-related anxiety groups. For this reason, these patients may be placed on a waitlist (meaning participants low-vision rehabilitation may be delayed), until the study team can match with someone in one of the other groups.

Behavioral: Low Vision Rehabilitation (LVR)

Arm 2 - ERT (after randomization) and then concurrent with LVR

EXPERIMENTAL

Participants with vision-related anxiety (must meet this per protocol by self-reports) randomized to this arm will receive immediate ERT. The LVR therapy will start approximately during 4-6 sessions of ERT.

Behavioral: Low Vision Rehabilitation (LVR)Behavioral: Emotion Regulation Therapy (ERT)

Arm 3- LVR with delayed ERT

EXPERIMENTAL

Participants with vision-related anxiety (must meet this per protocol by self-reports) randomized to this arm will receive LVR with delayed ERT.

Behavioral: Low Vision Rehabilitation (LVR)Behavioral: Emotion Regulation Therapy (ERT)

Interventions

The initial session will be with an LVR specialist that will recommend vision-enhancing devices and techniques to improve participant's vision and mobility functionality depending on needs. The devices will be given at no cost and include, but are not limited to: magnifiers that participants can hold or wear, glasses attachments that help filter out light to see better, or items that help with glare or seeing color. This session will be followed by at least one session with an occupational therapist, that will train participants to use the devices (take home and use) and recommend/teach ways to achieve functional goals. Most participants will be asked to attend 2-4 visits, but additional visits may be needed depending on needs and progress toward functional goals. Additional visits if orientation and mobility training is also recommended. Participants will be asked to share experiences approximately 1-week after all visits.

Arm 1 - Low Vision Rehabilitation LVRArm 2 - ERT (after randomization) and then concurrent with LVRArm 3- LVR with delayed ERT

There will be ten 1-hour weekly sessions of specialized psychotherapy with an ERT-trained therapist. These are typically done virtually but may be able to provide in-person sessions to those where this is needed. At the beginning of each session, the therapist will give participant's several questionnaires to learn about participant's experience with ERT. Questionnaires will also be completed after all sessions are completed.
