Abstract

Importance: Identifying and prioritizing unanswered clinical questions may help to best allocate limited resources for research associated with the treatment of age-related macular degeneration (AMD).

Objective: To identify and prioritize clinical questions and outcomes for research associated with the treatment of AMD through engagement with professional and patient stakeholders.

Design, setting, and participants: Multiple cross-sectional survey questions were used in a modified Delphi process for panel members of US and international organizations, the American Academy of Ophthalmology (AAO) Retina/Vitreous Panel (n=7), health care professionals from the American Society of Retinal Specialists (ASRS) (n=90), Atlantic Coast Retina Conference (ACRC) and Macula 2017 meeting (n=34); and patients from MD (Macular Degeneration) Support (n=46). Data were collected from January 20, 2015, to January 9, 2017.

Main outcomes and measures: The prioritizing of clinical questions and patient-important outcomes for AMD.

Results: Seventy clinical questions were derived from the AAO Preferred Practice Patterns for AMD and suggestions by the AAO Retina/Vitreous Panel. The AAO Retina/Vitreous Panel assessed all 70 clinical questions and rated 17 of 70 questions (24%) as highly important. Health care professionals assessed the 17 highly important clinical questions and rated 12 of 17 questions (71%) as high priority for research to answer; 9 of 12 high-priority clinical questions were associated with aspects of anti-vascular endothelial growth factor agents. Patients assessed the 17 highly important clinical questions and rated all as high priority. Additionally, patients identified 6 of 33 outcomes (18%) as most important to them (choroidal neovascularization, development of advanced AMD, retinal hemorrhage, gain of vision, slowing vision loss, and serious ocular events).

Conclusions and relevance: Input from 4 stakeholder groups suggests good agreement on which 12 priority clinical questions can be used to underpin research related to the treatment of AMD. The 6 most important outcomes identified by patients were balanced between intended effects of AMD treatment (eg, slowing vision loss) and adverse events. Consideration of these patient-important outcomes may help to guide clinical care and future areas of research.
