Trial summary

Epiretinal membrane (ERM) is a pathological phenomenon requiring surgery when vision is altered. ERM surgery requires ERM peeling, then active internal limiting membrane (ILM) peeling if it is not spontaneously peeled with ERM. Read more about this study

About this study

Official title: Observational Prospective Monocentric Study Evaluating "Sweeper" Use During Epiretinal Membrane Surgery

Epiretinal membrane (ERM) is a pathological phenomenon requiring surgery when vision is altered.

ERM surgery requires ERM peeling, then active internal limiting membrane (ILM) peeling if it is not spontaneously peeled with ERM. Initiation of peeling is very delicate and can lead to micro scotoma when realized with microscopic forceps. The Sweeper is a microscopic tool with a soft silicon tip covered with diamond dust which allows peeling initiation without retina prehension. It may reduce retinal trauma and visual sequelae.

Purpose of our study is to evaluate use of sweeper during 20 ERM surgeries. The investigator will compare microperimetry before surgery versus those after 1 month (M1) and 3 months (M3), and measure difference of number and depths of micro scotoma.

The investigator will note: number of forceps uses if sweeper is inefficient and all areas of sweeper use to correlate them with micro scotoma.

The investigator will evaluate visual and optical coherence tomography improvement after surgery.

Read the detailed description

Epiretinal membrane (ERM) is a pathological phenomenon that leads to visual loss, visual distortions, central scotoma, and diplopia. No medical treatment is yet available.

ERM surgery requires separation of normal retina and epiretinal membrane. After epiretinal peeling, if internal limiting membrane (ILM) is not spontaneously peeled with ERM, surgeon peels ILM from retina (also named active peeling). Initiation of peeling is very accurate and delicate. Either microscopic forceps or sweeper are used to initiate peeling. Sweeper is a microscopic tool with a soft silicon tip covered with diamond dust which allows peeling initiation without retina prehension. It may reduce retinal trauma and visual sequelae.

ILM active peeling reduces recurrence of ERM and rate of repeat surgery. No visual acuity loss has been found. But 2 studies show increase of micro scotoma at micro-perimetry after active ILM peeling with forceps.

Purpose of our study is to evaluate use of sweeper during 20 ERM surgeries. The investigator will compare microperimetry before surgery versus those after 1 month (M1) and 3 months (M3), and measure difference of number and depths of micro scotoma.

The investigator will note: number of forceps uses if sweeper is inefficient, all areas of sweeper use to correlate them with micro scotoma.

The investigator will evaluate visual and optical coherence tomography improvement after surgery.

Our study doesn't include any intervention while surgeries would be realized with or without study participation. Examinations are non-invasive, usual, and done during usual medical visit without additional visit.

What is being measured

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

  1. Difference of number and depth of micro scotoma before and after epiretinal membrane (ERM) surgery with sweeper

    Measured: microperimetry at baseline, then 1 month after surgery (M1), then 3 months after (M3)

Secondary outcomes (3)
  1. Efficacy of sweeper mesured by number of forceps uses if sweeper is inefficient

    Measured: Day of surgery

  2. Visual improvement measured by visual acuity and optical coherence tomography improvement after surgery , visual acuity and OCT morphometry before surgery, M1 and M3

    Measured: at baseline, then 1 month after surgery (M1), then 3 months after (M3)

  3. Optical coherence tomography (OCT) improvement after surgery measured by OCT morphometry

    Measured: at baseline, then 1 month after surgery (M1), then 3 months after (M3)

Questions about this trial

What is this clinical trial studying?

An observational study of Epiretinal Membrane, run by Nantes University Hospital at 1 site in France.

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 9 Oct 2024. 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 France. 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?

Difference of number and depth of micro scotoma before and after epiretinal membrane (ERM) surgery with sweeper (time frame: microperimetry at baseline, then 1 month after surgery (M1), then 3 months after (M3)). 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 NCT03350607, which also lists 4 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 9 Oct 2024.
