Ultrastructure Analysis of Excised Internal Limiting Membrane in Eyes of Highly Myopia With Myopic Traction Maculopathy
An observational study of Myopic Traction Maculopathy, run by Kyorin University at 1 site in Japan.
Trial summary
The excised ILM from 7 eyes of 7 patients with MTM including 7 eyes with macular retinoschisis and 4 eyes with foveal detachment but without any retinal break underwent vitrectomy with induction of posterior vitreous detachment and ILM peeling was examined to evaluate ultrastructure with electron microscopy.

Questions about this trial
What is this clinical trial studying?
An observational study of Myopic Traction Maculopathy, run by Kyorin University 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 19 Aug 2015. 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?
Visual acuity before and after surgery (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 19 Aug 2015.
