Impairment of the choroidal vascularity index was related to the rate of geographic atrophy enlargement at 2 years of follow-up, according to a study.
Riccardo Sacconi, MD, FEBO, and colleagues wrote that previous studies have shown that choroidal damage has a role in the pathogenesis of geographic atrophy (GA).
“In detail, previous histological studies suggested that the choroidal vascular impairment and the changes of the choroidal stroma could lead to the progression of [dry age-related macular degeneration],” they wrote. “However, histological analyses are affected by
