Reticular Pseudodrusen Voids after Rhegmatogenous Retinal Detachment.

We present a case of reticular pseudodrusen (RPD) regression on multimodal retinal imaging following a rhegmatogenous retinal detachment. Two mechanisms of action can be postulated. The subretinal deposits dissolve due to voluminous subretinal fluid during retinal separation from the retinal pigment epithelium and are in turn mechanically cleared during retinal re-attachment surgery. Alternatively, an RPD clearance is facilitated by enhanced phagocytic activity of macrophages and microglial cells as a response to acute retinal stress.
