About this study

Official title: Incidence and Factors Related to Macular Hole Reopening

The purpose of this investigation was to determine the incidence and the factors that cause a reopening of a macular hole (MH) after a surgical closure.

Read the detailed description

A reopening of a macular hole (MH) is a well-known complication of successfully closed MHs. Recently, internal limiting membrane (ILM) peeling has become widely used as an adjunctive procedure during MH surgery. The incidence of a reopening of a MH is 0 to 8.6% in eyes in which the ILM was peeled off, and 2 to 16% in which the ILM was not peeled off. Part of the variation in the percentages of reopening was the length of the follow-up period; eyes with longer follow-up periods have higher incidences of reopening.

What participants receive

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

  • VitrectomyProcedure or surgery

    Patients underwent vitrectomy with or without internal limiting membrane (ILM) peeling for an idiopathic full-thickness macular holes. Simultaneous phacoemulsification with intraocular lens implantation was performed on all phakic patients who were >40-years-of-age.

What is being measured

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

  1. A complete clinical examination including BCVA, slit-lamp biomicroscopy with a contact lens, indirect ophthalmoscopy, and fundus photography were performed post surgery.

    Measured: Patients were examined preoperatively and postoperatively on day one, and at two weeks, and one, three, and six months. Thereafter, they were examined every three to six months.

Questions about this trial

What is this clinical trial studying?

An observational study of Vitrectomy, run by Shinjo Ophthalmologic Institute at 1 site in Japan.

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 25 Jun 2009. 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 Japan. 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?

A complete clinical examination including BCVA, slit-lamp biomicroscopy with a contact lens, indirect ophthalmoscopy, and fundus photography were performed post surgery. (time frame: Patients were examined preoperatively and postoperatively on day one, and at two weeks, and one, three, and six months. Thereafter, they were examined every three to six months.). 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 NCT00927628, which also lists 6 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 25 Jun 2009.
