Incidence and Risk Factors for Progression of Pachychoroid Subtype

In this study among a relatively small cohort of 4 different levels of pachychoroid subtype, progression to a worse level was infrequent, as was worsening of visual acuity or choroidal thickening. Neovascularization was unusual and occurred exclusively in eyes with shallow, irregular retinal pigment epithelium elevation, suggesting the importance of this imaging feature if confirmed in subsequent studies.
