About this study

Official title: Utility of Visual Pattern Recognition Technology in Retinal Prosthesis Patients: the ARGUSII/ORCAM Device Study

This study is being done to determine if wearable text-to-speech (TTS) and visual pattern recognition (VPR) technology can be used to extend the capabilities of the Argus II to allow patients to read and recognize faces and objects.

The Argus II retinal prosthesis can restore rudimentary forms of vision to patients with bare light-perception vision. Using the prosthesis, patients can identify obstacles, handles, switches, eating utensils and demonstrate improved navigation when used in conjunction with other ambulation-assist tools. Current limits in the resolution of the device prevent useful reading or face recognition. The FDA has approved the Argus II as a humanitarian device.

Present-day wearable text-to-speech converters are also capable of object and face recognition. Such systems have been developed to assist with these tasks in patients with severe low-vision. ORCAM is a commercially-available eyeglass-mounted visual pattern recognition system capable of converting photographs of text to speech. It is comprised of a camera, a small belt-worn computer, pattern recognition software and a small audio transducer. ORCAM can acquire the image of a sheet of paper and read the text to the user through a small speaker adjacent to the ear. In addition, ORCAM can be trained to recognize faces and speak the name of the individual to the user. ORCAM can also be used to recognize everyday products after being programmed.

Read the detailed description

The Orcam device will be mounted onto the Argus II eyeglasses. The subject will be asked to use the Orcam device with and without the Argus II. After a half-day interactive training session with the Orcam device, the investigators will interview the subject with a questionnaire. The investigators will then contact the subject every two weeks via a telephone call for two months (4 phone interviews). The investigators will then ask the subject to return to Mayo Clinic to demonstrate their ability to use the Argus II and Orcam together and separately. These sessions will be videotaped.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Argus II EyeglassesDevice

    The Argus II Eyeglasses (retinal prosthesis) can restore rudimentary forms of vision to patients with bare light-perception vision. Using the prosthesis, patients can identify obstacles, handles, switches, eating utensils and demonstrate improved navigation when used in conjunction with other ambulation-assist tools. Current limits in the resolution of the device prevent useful reading or face recognition.

  • ORCAMDevice

    ORCAM is a commercially-available eyeglass-mounted visual pattern recognition system capable of converting photographs of text to speech. It is comprised of a camera, a small belt-worn computer, pattern recognition software and a small audio transducer. ORCAM can acquire the image of a sheet of paper and read the text to the user through a small speaker adjacent to the ear.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects Who Are Able to Use the ORCAM device With the Argus II Device at the End of the Study

    Subjects will be familiar with using their retinal prosthesis, the Argus II Device. At baseline, the ORCAM device will be mounted on the Argus II eyeglasses.

    Measured: End of study, approximately 4 months

Questions about this trial

What is this clinical trial studying?

A study testing Argus II Eyeglasses and ORCAM in people with Retinitis Pigmentosa, run by Mayo Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Subjects Who Are Able to Use the ORCAM device With the Argus II Device at the End of the Study (time frame: End of study, approximately 4 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jan 2022.
