Novel Drug Delivery Systems for the Treatment of Glaucoma

AbstractPurpose of ReviewIn this article, we review new and emerging drug delivery methods used in the treatment of glaucoma.Recent FindingsSeveral methods for sustained delivery of glaucoma medications have shown promise recently. Drug-eluting punctal plugs, contact lenses, and fornix-based silicone rings as well as subconjunctival and intracameral injections or implants are either in development or clinical trials. Thus far, those studied have demonstrated significant intraocular pressure (IOP) lowering ability with favorable safety profiles. However, long-term clinical safety data and comparative trials with existing therapies have been limited.SummaryPatient adherence with medication regimens remains a major obstacle in preventing glaucoma progression. Emerging patient-independent platforms that can deliver IOP lowering therapeutics hold promise for enhancement of adherence to treatments while remaining safe and effective. Each of these systems has their own unique advantages and disadvantages. It is still unclear where each of these products will fit into individual patient and practitioner treatment algorithms.
