What is being measured
The primary outcome is the main question the study is designed to answer.
Anterior Angle Width Using Anterior Segment Optical Coherence Tomography (AS OCT)
The angle width formed between the eye's cornea and iris in both eyes was measured in microns (µm) using AS OCT, a laser-based, noninvasive, diagnostic system providing high-resolution images of the eye.
Measured: Day 1
Secondary outcomes (2)
Number of Study Eyes in Each Shaffer Grade Using Gonioscopic Lens
The angle width formed between the cornea and iris in both eyes was measured by gonioscopy using Shaffer grading where: grade 4=wide open, grade 3=moderately open, grade 2=moderately narrow, grade 1=very narrow or grade 0=closed. The number of eyes in each Shaffer Grade is reported.
Measured: Day 1
Number of Study Eyes in Each Step Grade Using Gonioscopic Lens
The angle width formed between the cornea and iris in both eyes was measured by gonioscopy using Large Step Grading ranging from 1.0 (smallest angle width) to 7.5 (largest angle width) with 0.5 unit intervals where each Large Step unit represented a fixed length of approximately 200 µm. The number of eyes in each Large Step Grade is reported.
Measured: Day 1

Questions about this trial
What is this clinical trial studying?
An observational study of Open-angle Glaucoma and Ocular Hypertension, run by Allergan 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 2 inclusion and 2 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: stopped early, as of the sponsor's last update on 31 Jul 2014. 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.

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?
Anterior Angle Width Using Anterior Segment Optical Coherence Tomography (AS OCT) (time frame: Day 1). 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.
