About this study
In this study, the investigators want to investigate the success of aqueous humor shunting in the retrobulbar space, using the eyeTube in combination with the eyeWatch implant. The investigators postulate that posterior aqueous humor shunting would be more effective, as this space offers a larger drainage area and a less aggressive local inflammatory environment than the subconjunctival space close to the limbus, resulting in lower and better-sustained IOP than in the more limited, fibroblast-promoting subconjunctival environment surrounding standard implants.

Clinical summary

Where is the study taking place?
The record lists 1 site in Senegal. 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?
Results are not available in the source record.
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?
Intraocular pressure (IOP) reduction (time frame: 12 months). The study lists 2 primary outcomes in all. 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 31 Aug 2023; AzTrials last refreshed its copy on 6 Nov 2026.
