HUA, characterized by elevated levels of uric acid in the blood, has been implicated in various epiretinal pathologies such as diabetic retinopathy, age-related macular degeneration, and epiretinal membranes. Managing HUA could potentially mitigate these conditions by addressing the underlying metabolic and inflammatory processes. The table summarizes potential therapeutic approaches targeting HUA for the management of epiretinal pathologies, based on recent research findings. These approaches include pharmacological interventions, lifestyle modifications, and dietary supplements, each with specific mechanisms of action and potential benefits in ocular health
