Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 5 years and older
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Presence of an eyelid movement disorder for at least one eye, moderate cognitive function or better defined as greater than or equal to 18 out of 30 on a pre-screening of the Mini-Mental State Exam, age 5 or older.

Who cannot join

  • Absence of an eyelid movement disorder or presence of a corneal ulcer. Those with a corneal ulcer are at risk for permanent loss of vision and should be managed with proven methods. Age less than 5, Severe Cognitive impairment defined as Mini-mental score <18, behaviors consistent with delirium (combinations of disorientation, hallucinations, delusions, and incoherent speech), or lethargy. These individuals must be excluded since participation requires competent self-care, reliable responses and cooperation during fitting of the devices.

About this study

Official title: Non-surgical Correction of Eye Lid Paralysis With External Magnet Systems

Objective 1: Determine the safety and feasibility of externally mounted magnets for extended management of chronic eyelid movement disorders by measuring visual acuity and corneal and skin integrity and comfort over 8 weeks of wear. Objective 2: Collect preliminary data on the relative efficacy of external magnetic devices by comparing them to externally mounted lid weights and ptosis crutches using rating scales and video analysis of blink biomechanics.

Read the detailed description

Two major types of eye lid movement disorders include lagophthalmos (incomplete closure of the eyelids) and blepharoptosis (incomplete opening of the eyelids). Both of these conditions occur because of a disruption in the normal agonist-antagonist neuro-muscular complex balance. Generally paralysis of the eyelid or facial muscles is responsible for the abnormality (the eyelids can close but not open, or open but not close). An external device, if able to generate an appropriately balanced force, could restore eyelid movement by performing the paralyzed function; for example, a ptotic (droopy) eyelid could be opened, and the functioning eyelid closure muscle could overcome the device's force. In prior work the investigators established proof-of-concept data demonstrating safety and efficacy for temporary management of ptosis up to 2 hour per day for 2 weeks. Preliminary data suggest similar safety for lagophthalmos. This study will expand on this preliminary work to examine longer wear times, home use, and feasibility for a wider range of eye lid disorders.

What participants receive

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

  • Magnetic lid systemDevice

    Also called Magnetic Levator and Magnetic Orbicularis

    Small externally mounted magnetic lid arrays are attached to the eye lid (s). Glasses with a second magnet system may be combined with the arrays depending on the lid condition. The device intends to facilitate eye opening and closing.

What is being measured

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

  1. Rating Scale of Skin Integrity

    Ratings at the beginning and end of treatment will be analyzed by calculating the mean and standard deviation of the skin erythema rating across all available time points. The outcome measure is the FDA scale, Assessing the Irritation and Sensitization Potential of Transdermal and Topical Delivery Systems for ANDAs Guidance for Industry. Range is 0 to 7 with higher numbers being worse skin erythema.

    Measured: Baseline and up to 32 weeks

Secondary outcomes (2)
  1. Count of Participants With Adverse Corneal Events Based on National Eye Institute Rating Scale

    Using the National Eye Institute Rating Scale (0 to 3 points with higher being more staining), cases where staining increased more than 2 points or if there was any ulceration, an adverse event was tabulated and summed for each participant over 1 up to 32 weeks of use, depending on how long the participant was followed.

    Measured: Baseline and up to 32 weeks

  2. Change in Visual Acuity

    Visual acuity at 20ft before treatment and after 1 week or more. Difference between weekly acuity measures to baseline was calculated and averaged for each subject, and then a group mean and standard deviation calculated.

    Measured: Baseline and up to 32 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Magnetic lid system in people with Blepharoptosis and Lagophthalmos, run by Kevin Houston 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 1 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 30 Oct 2020. 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?

Yes. Results are posted in the registry (first posted 30 Oct 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Rating Scale of Skin Integrity (time frame: Baseline and up to 32 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02988856, which also lists 1 linked publication.

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 30 Oct 2020.
