Background

Existing therapeutic agents are regularly delivered to the subconjunctival space of the eye, which requires a practitioner who is surgically trained. Further, a new class of sustained-release agents are being developed to treat glaucoma and will be deployed into the subconjunctival space. Glaucoma is the second most common cause of blindness, estimated to affect nearly 80 million people by 2020. Glaucoma has no cure, and all treatments seek to lower IOP (intraocular pressure) to slow or halt vision loss from the disease. Eye drops are currently the most used therapy, but users suffer from multiple drawbacks such as difficulty when self-administering and non-compliance. Adoption of new sustained-release subconjunctival drug formulations will require a device for safe and easy injection
