December 11, 2023 updated by: Yannis Paulus, University of Michigan

Device for Monitoring Age-related Macular Degeneration (AMD)

This study involves user acceptability and feedback of KalEYEdoscope, a digital, handheld device utilizing shape-discrimination hyperacuity to distinguish the severity of age-related macular degeneration (AMD).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a patient-experience study being conducted at the Kellogg Eye Center in Ann Arbor in the outpatient setting. Patients who agree to enroll in the study will test the device and provide user feedback via a questionnaire as well as complete questionnaires about their visual function. The preliminary study looks at the usability of using this device for monitoring of age-related macular degeneration, obtaining user feedback to enhance the design. In the future, developing such a device for home monitoring of macular degeneration may increase access to timely treatment to prevent vision loss.

To gather user feedback on a digital, non-invasive, handheld device in the outpatient AMD patient population, with the goal of developing a user-friendly, portable device to monitor AMD progression, this study assesses the usability, comfort, duration, ergonomics, and ease of use of the device among AMD patients in a single session.

Data collected during the test may include but is not limited to the length of the test, boot time, screen transition time. The participants will then fill out the Visual Function Questionnaire-25, the System Usability Scale (SUS), and may include targeted questions designed by the study team to evaluate the participant experience with the device and visual function.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

age-related macular degeneration

Description

Inclusion Criteria:

  • Any patient aged 18 years or older with age-related macular degeneration who is seen at the Kellogg Eye Center.

Exclusion Criteria:

  • pregnant women, prisoners, severe cognitive impairment, and diagnoses (mental or neuromuscular disorders) which could preclude independent use of the device.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
System usability scale
Time Frame: immediate during a single office visit - generally 5- 15 minutes
Obtain user feedback via a questionnaire and evaluate the usability of using this device.
immediate during a single office visit - generally 5- 15 minutes

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
National Eye Institute Visual function questionnaire (NEI VFQ 25)
Time Frame: immediate during a single office visit - generally 5- 15 minutes
Participants complete 25-question questionnaire about their visual function.
immediate during a single office visit - generally 5- 15 minutes
Participant Experience Survey
Time Frame: immediate during a single office visit - generally 5- 15 minutes
Participants complete 8 qualitative questions with a Likert scale about the device and using the device.
immediate during a single office visit - generally 5- 15 minutes

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 10, 2022

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
