ABSTRACT
Age-related macular degeneration is a major cause of blindness worldwide characterized by the presence of drusen and leading to retinal pigment epithelium and outer retinal changes in advanced stages. Approximately 10% of eyes with age-related macular degeneration develop neovascular complications and present with retinal or sub-retinal pigment epithelium exudation, hemorrhage, or both. Recent advances in imaging techniques, especially optical coherence tomography (OCT), help in early identification of disease and guide various treatment decisions; however, not all signs are suggestive of ongoing exudation or neovascular activity. Although uncommon, multiple OCT-based signs are reported that may be difficult to appreciate clinically. Prompt identification of these signs such as outer retinal tubulation, cystoid degeneration, or pseudocysts may avoid unnecessary interventions. Moreover, certain OCT-based features involving the choroid, such as prechoridal cleft and choroidal cavern, have also been found in eyes with age-related macular degeneration. We discuss these unique OCT-based signs, their pathogenesis, clinical relevance, and management.
