Brief summary

The purpose of this Post-Market Clinical Follow-Up (PMCF) study is to assess long term clinical performance and safety outcomes for EX-PRESS Glaucoma Filtration Devices Models P-50 and P-200.

Detailed description

This is a non-interventional/observational study designed as a retrospective chart review. Study sites will identify patient charts within their existing databases in a fair and consistent manner, e.g., reviewing all eligible charts in reverse chronological order by year of baseline visit. Patients meeting the eligibility criteria who have a minimum of 5 years of follow-up data since the implantation of the P-50 or P-200 device will be enrolled, including patients whose 5-year standard of care visit is scheduled during the study enrollment period. The overall study duration is expected to be approximately 7 months.

Interventions

DEVICEEX-PRESS P-50 filtration device

FDA-approved, stainless steel device with a 50-micron internal lumen size indicated for the reduction of intraocular pressure in glaucoma patients where medical and conventional surgical treatments have failed

DEVICEEX-PRESS P-200 filtration device

FDA-approved, stainless steel device with a 200-micron internal lumen size indicated for the reduction of intraocular pressure in glaucoma patients where medical and conventional surgical treatments have failed

Inclusion criteria

Key Inclusion Criteria: * Able to understand and sign an Institutional Review Board (IRB) / Independent Ethics Committee (IEC) approved informed consent form authorizing data collection prior to the review of any medical records; * Implanted (one eye or both) with the EXPRESS P-50 or EXPRESS P-200 device per indications for use for at least 5 years; * Have a minimum of 5 years of recorded follow-up data; * Other protocol-specified inclusion criteria may apply. Key

Exclusion criteria

* Enrolled in any clinical trial within the last 5 years; * At the time of implantation: 1. Presence of ocular disease such as uveitis, ocular infection, severe dry eye, severe blepharitis. 2. Pre-existing ocular or systemic pathology that, in the opinion of the surgeon, is likely to cause postoperative complications following implantation of the device. 3. Diagnosed with angle-closure glaucoma. * Other protocol-defined
