Trial summary

Full-thickness macular Hole associated with macular detachment is a one of the maculopathies of high myopia. There is controversy in the primary treatment for this situation. This study will compare the effects of macular buckling versus vitrectomy in a cohort of highly myopic eyes with this situation. Read more about this study

About this study

Official title: A Randomized, Open Label, Single Center Study Comparing the Efficacy of Macular Buckle Versus Vitrectomy on Full-thickness Macular Hole and Concurrent Macular Detachment in Eyes With Highly Myopia

Full-thickness macular Hole associated with macular detachment is a one of the maculopathies of high myopia. There is controversy in the primary treatment for this situation. This study will compare the effects of macular buckling versus vitrectomy in a cohort of highly myopic eyes with this situation.

Read the detailed description

A randomized, open label, single center study comparing the efficacy of macular muckle + gas injection versus internal limiting membrane peeling + gas tamponade on full-thickness macular hole associated with macular detachment in eyes with high myopia.

Being tested
Buckle, Vitrectomy, Limbal paracentesis, Gas injection, Peeling internal limiting membrane
Keywords
macular buckling, full-thickness macular hole, macular detachment, internal limiting membrane peeling, high myopia

What is being measured

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

  1. Retinal re-attachment rate

    Successful rate of reattachment of macular retina after surgery

    Measured: 1 month

Secondary outcomes (2)
  1. Macular hole status

    Closure rate of macular hole after surgery on optical coherence tomography

    Measured: 3 month

  2. Post-operative best corrected visual acuity

    Best corrected visual acuity of the eyes after surgery

    Measured: 3 month

Questions about this trial

What is this clinical trial studying?

A study testing Buckle, Vitrectomy and Limbal paracentesis in people with Macular Holes and High Myopia, run by Sun Yat-sen University at 1 site in China.

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 4 inclusion and 4 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 2018. 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 China. 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?

Retinal re-attachment rate (time frame: 1 month). 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 NCT03433547, which also lists 2 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 2018.
