title: Practice patterns and treatment changes for open-angle glaucoma: the RiGOR study.
abstract: OBJECTIVE
  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.
  
  
  CONCLUSIONS
  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.
