Long-term Safety and Efficacy of a Sustained-Release Bimatoprost Ocular Ring

For patients with glaucoma, reduction of intraocular pressure (IOP) is the only proven treatment to slow or halt disease progression.1 However, nonadherence to daily eye drops is a well-documented problem.2,3 Most clinicians acknowledge that it is difficult to determine which patients are likely to be noncompliant. Several methods are being developed to deliver medication in a sustained-release manner via implantable reservoirs or external applications, such as contact lenses or punctal plugs. We report on long-term safety and retention of a bimatoprost ocular ring (BIM ring) that delivers bimatoprost over a 6-month period.
