Choroidal Morphology Changes After Aflibercept Therapy in Pachychoroid Neovasculopathy

Summary

In the present study, investigators attempt to evaluate the short-term, detailed changes in choroidal morphology after three monthly injections of aflibercept in pachychoroid neovasculopathy. The association between these changes and clinical outcomes will be additionally investigated. The primary purpose of this study is to provide reference data regarding the aflibercept-related morphologic changes that implicate structural and functional choroidal alteration, and hence its clinical implications.
