Study summary

The purpose of the study "Usability and Ergonomic Evaluation of Self-Positioning System for Retinal Imaging" is to enable self-operation of a monitoring device in home-simulated environment

Read the detailed description

One of the main challenges in developing a retinal imager is to design it to be self-operated by elderly patients in their home setting The study's objective is to explore ergonomic solutions that will allow the user to perform imaging on their own. The study will be done in a home-simulated environment using a dedicated ergonomic system (termed "PAF" - Positioning And Fixation system) that stimulates the retinal imager and enables to record the tested subject using standard cameras. The prototype doesn't include the retinal imager and does not include any imaging capabilities aside from standard means of photography Subjects will be evaluating for positioning accuracy and comfort by comparing different methods. Pupil position will be recorded using commercial off the shelf cameras when the subject is performing simple ergonomic tasks while looking at a screen presenting images.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

    Usability and Ergonomic Evaluation of Self-Positioning System

    Device: PAF (Positioning And Fixation device)

Interventions

  • DevicePAF (Positioning And Fixation device)

    Up to 60 Subjects will be evaluating for positioning accuracy and comfort by comparing different methods utilizing the PAF device. Some methods of positioning will be applied and compare for each usability factor X, Y, Z location, and fixation. The patient will be evaluated before pupil dilation. VA and ophthalmic diagnoses will be recorded. Pupil position will be recorded using 3 commercial off the shelf cameras when the subject is performing simple ergonomic tasks while looking at a screen presenting images. Each testing session will be limited 20 min long. Subjects will be able to rest within the testing session if required. Total session time per patient will not exceed 30 minutes.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Sep 2017 to primary completion in Feb 2018, 4 months.

Of 51 interventional studies with no phase under Macular Edema, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 37. This study's 4 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 13, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
