Case demonstrates effects of Müller cell activation on photoreceptor loss in multifocal geographic atrophy, indicating potential protective roles.
This multifocal GA case demonstrates how MC activation and structural changes surrounding individual drusen could coalesce, contributing to photoreceptor loss. Müller cells penetrating basal laminar deposits and encasing calcified drusen suggests attempting clearing and/or protecting the retina from harmful contents.
