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.

Study Type

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Man or woman over 18 years of age, less than 75 years
  • Macular Hole of all etiologies
  • Patient with history of opened macular hole after previous pars plana vitrectomy
  • Delay between previous surgery and inclusion (relapse or non-closing hole) > 1 month
  • Patient who received the study information and provided consent
  • Patient who is a members or a beneficiary of a national health insurance plan

Exclusion Criteria:

  • Ocular surgery other than the macular hole surgery in the prior 3 months
  • Participation in other clinical studies in the prior 3 months
  • Any current or prior ocular pathology that could interfere with the conduct of the study, including visually significant cataract or media opacity
  • Patient with uncontrolled glaucoma on more than 1 intraocular lowering medication
  • Patient with uveitis or other active ocular inflammation or infection
  • Pregnant or breast-feeding woman. Women of childbearing age will be asked to undergo a pregnancy test before being enrolled into the study or to use an effective birth control method
  • Person deprived of liberty by judicial or administrative measures
  • Any other reason which in the opinion of the investigator would preclude the adherence of the schedules visits, safe participation in the study or affect the results of the study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Visio-AMTRIX
Disk of amniotic membrane apposed or buried on recurrent macular hole by the Investigator after vitrectomy and fluid-gas exchange.
Biological: Visio-AMTRIX
Chemically-treated, viro-inactivated, freeze-dried and irradiated amniotic membrane placed by the investigator during macular hole surgery

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
Closure of recurrent macular hole
Time Frame: 6 months
Macular hole closure evaluated by optical coherence tomography (OCT)
6 months

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
Absence of adverse reaction
Time Frame: 7 days, 15 days, 1 month, 3 months, 6 months
Analysis of all adverse events and comparison with adverse events observed after vitrectomy
7 days, 15 days, 1 month, 3 months, 6 months
Functional restoration after closure of the macular hole
Time Frame: 7 days, 15 days, 1 month, 3 months, 6 months
Best corrected visual acuity (BCVA) and microperimetry assessment
7 days, 15 days, 1 month, 3 months, 6 months
Anatomical restoration
Time Frame: 1 month, 3 months, 6 months
Anatomical restoration of the outer segments (external limiting membrane and ellipsoid layer). Anatomical changes in the ganglion cell layer of the retina in the area around the hole and under the membrane. The assessment is done by OCT measuring the thickness of the ganglion cell layer
1 month, 3 months, 6 months
Evaluation of the surgical technique of placing the membrane
Time Frame: 7 days, 15 days, 1 month, 3 months, 6 months
Duration of coverage by Visio-AMTRIX and persistent after gas removal
7 days, 15 days, 1 month, 3 months, 6 months

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.
