About this study

The purpose of this study is to determine normal eyelid sensation distribution using a Cochet-Bonett Aesthesiometer.

Read the detailed description

After proper taken consent patients without previous eyelid surgery in the Oculoplastic clinic at Duke Eye Center and Duke Aesthetic Center will be enrolled to test the eyelid sensation distribution using the Cochet-Bonnet aesthesiometer. The aesthesiometer (Luneau ophthalmologie) with a 0.12mm diameter filament was chosen for its ease of use, sensitivity, and safety. This instrument contains a 6 cm long, retractable, flexible monofilament. For any given length, when applied perpendicularly to test surface, the filament will exert a precise pressure before visibly bending. The filament length inversely corresponds to the pressure exerted by the aesthesiometer.

Selection of eyelid laterality will be randomized on the same day of the study. Ipsilateral upper and lower eyelids will be divided in thirds (medial, central and lateral borders) including the margin (fig.2). The eyelid sensation will be tested on every third by applying the tip of the aesthesiometer filament perpendicular to the eyelid skin and tarsal plate until the filament bent slightly. The filament length will be set at 6 cm (longest length) and applied to the test site 3 times. This process will be repeated 3 times and if the patient verbally responded to the 3rd touch, the number 6 will be recorder.

If the patient responded less than 3 of the 3 times, the filament will be shortened by 0.5 cm and the test will be repeated. This process will be continued by shortening the filament 0.5 cm each time, until the patient feels the filament touch 3 of 3 times. This filament length number will be recorded as the touch reading for that time period.

The mean touch thresholds for the various test sites will be compared using a Freidman two-way analysis variant (ANOVA).

Questions about this trial

What is this clinical trial studying?

A study testing Aesthesiometer in people with Normal Eyelid Sensation Distribution, run by Duke University 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 3 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 27 Feb 2017. 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?

Eyelids' sensation distribution (time frame: 1 year). 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 NCT02059824, which also lists 5 linked publications.

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 27 Feb 2017.
