Macular HoleNCT01680068
Air Tamponade in Macular Hole Surgery
A study testing Pars plana vitrectomy and postoperative air tamponade in people with Macular Hole, run by Helse Stavanger HF at 1 site in Norway.
Trial summary
Macular hole is a hole formation which takes place in the center of the retina. Such a hole needs surgical steps in order to close. Closure of the macular hole will lead to a substantially improvement of vision in most cases. Read more about this study

About this study
Macular hole is a hole formation which takes place in the center of the retina. Such a hole needs surgical steps in order to close. Closure of the macular hole will lead to a substantially improvement of vision in most cases. Following macular hole surgery a tamponade of intraocular gas is normally injected in order to keep the macula dry for the postoperative period. Postoperative face down position for a week was earlier standard. Several authors report of good closure rates with both air tamponade or lack of face down positioning. In this study standard pars plana vitrectomy with peeling of the internal limiting membrane (ILM) will be performed. The gas tamponade will be replaced by air. Postoperative face down positioning will not be used.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Macular hole is a hole formation which takes place in the center of the retina. Such a hole needs surgical steps in order to close. Closure of the macular hole will lead to a substantially improvement of vision in most cases. Following macular hole surgery a tamponade of intraocular gas is normally injected in order to keep the macula dry for the postoperative period. Postoperative face down position for a week was earlier standard. Several authors report of good closure rates with both air tamponade or lack of face down positioning. In this study standard pars plana vitrectomy with peeling of the internal limiting membrane (ILM) will be performed. The gas tamponade will be replaced by air. Postoperative face down positioning will not be used.

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?
Closure rate of macular hole (time frame: 1 month after enrollment). 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?
