GOUT AND RISK OF AGE-RELATED MACULAR DEGENERATION.

Area of Science:

• Ophthalmology
• Rheumatology
• Epidemiology

Background:

• Gout is a common inflammatory arthritis characterized by hyperuricemia.
• Age-related macular degeneration (AMD) is a leading cause of vision loss in older adults.
• The potential link between systemic inflammatory conditions and AMD is an area of ongoing research.

Purpose of the Study:

• To investigate the association between a diagnosis of gout and the incidence and progression of age-related macular degeneration (AMD).

Main Methods:

• A retrospective cohort study utilizing a multicenter healthcare research network.
• Identified patients with gout (ICD-10 code and uric acid-lowering agent prescription) and a matched control cohort without gout.
• Applied propensity score matching to control for baseline demographic and health status differences.

Main Results:

• Patients with gout showed a significantly increased risk of developing dry AMD (RR 2.73), advanced dry AMD (RR 2.64), and wet AMD (RR 2.48) within five years compared to controls.
• Gout patients also had a higher likelihood of requiring anti-VEGF therapy (RR 2.80).
• Similar increased risks were noted for AMD progression in patients with co-existing early AMD and gout.

Conclusions:

• Gout is associated with an elevated risk of AMD development and progression to advanced stages.
• Further research is warranted to elucidate the underlying mechanisms linking hyperuricemia and AMD.
• These findings suggest a potential role for managing hyperuricemia in AMD prevention or treatment.
