Practice patterns and treatment changes for open-angle glaucoma: the RiGOR study.

Aims: The RiGOR study provides a current picture of the types of glaucoma treatment over 12 months.

Methods: Patients were identified and enrolled at the time of decision to proceed with laser surgery procedure or other procedure such as incisional surgery or drainage device implantation, or initiation of a new or additional course of therapy with medication for glaucoma treatment.

Results: The most frequent type of treatments were prostaglandin analogues (60%) among patients with additional medication, selective laser trabeculoplasty (87%) among patients with laser surgery and trabeculectomy (57%) among patients with incisional surgery.

Conclusion: For 36% of patients, a treatment cascade involves two or more therapies over a year. This demonstrates the complex nature of open-angle glaucoma treatment.
