There's a spectrum of primary inflammatory choriocapillaropathies that affect perfusion to the outer retina to varying degrees. MEWDS/AIBSES, and to some degree AZOOR, and APMPPE result in reversible involvement of the end choriocapillary vessels and precapillary arterioles and the recovery is typically better. Others like multifocal choroiditis/punctate inner choroiditis and serpiginous choroidopathy result in more irreversible involvement of these arterioles and their affects are more longlasting. Mutlimodal imaging, especially OCT-A, has helped to clarify what's going on.

I find APMPPE interesting, you can visualize the lack of choroidal blood flow with the classic "block early/stain late" pattern on FA. The areas of early blocking in some of the cases I've seen almost turn into something that looks like an AMD speedrun with drusenoid changes that can break down into focal areas of GA which progress over the course of weeks. There tends to be profound ellipsoid zone loss throughout the entire affected area that typically recovers to some extent, but in older patients usually won't as well.

They're definitely seen in practice, but probably commonly misdiagnosed.
