Gibt es unterschiedliche Phänotypen bei der geografischen Atrophie der AMD? – Pilotstudie zur Differenzierung mittels multimodaler Bildgebung

Abstract: Zusammenfassung Hintergrund Bei der geografischen Atrophie (GA) im Rahmen einer altersabhängigen Makuladegeneration (AMD) entwickelt sich ein Verlust an Photorezeptoren (PR), retinalem Pigmentepithel (RPE) und Choriokapillaris (CC). Für therapeutische Ansätze ist es entscheidend, welche morphologische Struktur bei einem individuellen Patienten primär geschädigt ist und dann sekundäre Schädigungsprozesse initiiert. Wurde bisher das RPE mit seiner Lipofuszinakkumulation als primär geschädigte und zum U… Show more

“…Moreover, the area surrounding the GA margin was shown to reveal a significantly higher flow impairment compared to more eccentric areas in the same eye. These findings indicate that choriocapillaris degeneration may occur before the development of GA [30,31,[45][46][47][48]. Innovative adaptive optics investigations revealed that this choriocapillaris hypoperfusion even extended the region of increased cone spacing, an early sign of atrophic retinal processes [47].…”

“…Clinically, AMD is classified into ‘dry’ or atrophic form and ‘wet’ or neovascular form. About 1 out of 100 people between the ages of 65 and 75 have age-related macular degeneration [ 5 , 6 ]. There is currently no effective treatment for dry macular degeneration.…”
