RESUMO
BACKGROUND: Non-neovascular age-related macular degeneration (AMD) is not yet treatable. This article summarises current clinical research approaches. The reasons for the current lack of success are analysed. METHODS: Literature and databank search. RESULTS: The number of therapeutic approaches and mechanisms is limited. Only reduction in lipofuscin containing deposits is specific for AMD. Further approaches include modulation of inflammation and neuroprotection. Confirmatory studies have failed to demonstrate efficacy in AMD, i.e. slowing or stopping AMD progression. DISCUSSION: To increase the probability of success for future developments, the pharmacological target space needs to be broadened. This may be achieved by application of molecular network analyses. As visual acuity is commonly not primarily affected by non-neovascular AMD, research on patient perspective is required to define reasonable target profiles for future therapies.
