Background and study aims
This study is designed to evaluate the performance and safety of the Eagle® device when used within the intended use covered by the CE marking and following the Standard of Care. The Eagle device is a laser device for direct selective laser trabeculoplasty (DSLT) for the treatment of glaucoma. The laser treatment with the Eagle device is performed without the need to use a lens that touches the eye as in the traditional laser treatment. An image processing algorithm automatically localises the target area, which the operator or eye care professional (ECP) readjusts if necessary. Once the operator has confirmed the target area, an eye-tracking system enables the eye movement to be tracked so that the laser pulses are delivered precisely to the target area.
Who can participate?
Patients aged 18 years old and over who underwent treatment with the eagle device for treatment of open-angle glaucoma including exfoliative or pigmentary glaucoma or ocular hypertension as per the approved indication with expected post-operative follow-up data of at least six months
What does the study involve?
This study is a registry designed to evaluate the performance and safety of the Eagle® device when used within the intended use covered by the CE marking and following the Standard of Care. The study will register the information usually collected by your doctor at the time points specified by them. The only requirement is that two doctor visits be recorded so the performance and safety of the treatment with the Eagle device can be evaluated.
What are the possible benefits and risks of participating?
Participants are unlikely to derive any personal health benefits from participating in this study because the collection of data for the registry is independent of the standard of care decisions made by their doctor. However, the results of the study may help to better assess the treatment of glaucoma in the future.
As only data are collected in the study, participation is not associated with any medical risks beyond the ones related to your medical care as decided and performed by the doctor.

| Health condition(s) or problem(s) studied | Glaucoma and ocular hypertension |
| Intervention | The purpose of this registry is to evaluate the effectiveness and safety of the Eagle device when used within its designated use as outlined by the CE-marking and in adherence to standard care protocols. The information gathered will aid in the proactive monitoring of device performance and safety, aligning with the post-market surveillance requirements outlined in Regulation (EU) 2017/745. Initially, participants will undergo direct selective laser trabeculoplasty (DSLT) using the Eagle device to manage the elevated eye pressure associated with their glaucoma. This study seeks to analyze the average change in intraocular pressure (IOP) from baseline for 4-8 months post-treatment. The primary outcome assesses changes in IOP over time and the secondary outcomes will investigate the performance and safety of Eagle device in adult participants treated for open-angle glaucoma or ocular hypertension. This is an observational study and the data collection plan is not compulsory but offers a template for data collection depending on the standard of care in force at the site. The registry data will be collected at the three predefined post-treatment intervals of 0-4 months, 4-8 months and 8-12 months. When multiple visits occur within a single registry interval, then the latest available assessment taken within the interval is the one collected as part of the registry. Participants may not have data at all 3 post-treatment intervals. The following key data points are to be collected for both eyes, if performed by the investigators as part of the standard of care and where applicable the case report form will collect the information on right, left or both eyes, where applicable: Data collection before DSLT performed with the Eagle device: - Participant demographics (age and gender) - Ethnic group of the participant - Type of glaucoma - Angle pigmentation - Number and names of ocular medications at 1st treatment - Previous procedures Data collection on the day of standard of care DSLT performed with the Eagle device: - Date of procedure, baseline IOP, baseline BCDVA, baseline refraction - Treatment area (180° or 360◦) - Laser energy used for treatment on each participant’s eye - Physician’s assessment on the usability - Participant satisfaction after treatment Data collection after DSLT performed with the Eagle device: - IOP at each follow-up interval - Refraction at each follow-up interval (Optional) - Post-treatment surgical intervention - BCDVA at each follow-up interval - Name of ocular medications, if any, at follow-up intervals - Rates of Adverse Device Effects |
